Recently, he entered the pit of Dafa, and began to install accessories. Because the SLR and multiple shots that were used have all been large bags, he only bought two shots after Dafa, and he will bring another Fuji X100T daily. Therefore, there was a cheap but good-looking bag. Before this article was collected, it was considered to be a good value for money. Plus I used to buy a dpark. I thought that the quality of the bag was good, so it was a priority. Consider the 200+ bag.

Briefly introduced why this bag was chosen, and then discovered that 618 did not have any discount. The camera was bought without giving it a new home.

Such a special day, my orders are mainly in Jingdong, after some days continue to sun the other it, first briefly explain this bag I use a few days of feeling, just share this experience.

Unlike the color I used to see the value of my friend, I bought it in black, but it may be because of the revision. My Logo is different from him.

The reason I fancy it is only because it can meet my needs. At present, it is necessary to put one machine with two mirrors or two machines with two mirrors, and there are some mezzanines that can hold some small things.

Compared with the seller's show, the appearance is not so good, there are some feeling of folds, but the whole is still square, after all, the material is canvas material is also excusable.

There is also a comparison between the color scheme and Dafa's color scheme, so I may have decided to choose black for this reason.

The handle part has a piece of leather that can be buckled to facilitate our extraction.

After opening, you can see the inner suede, this is relatively compact compared to the previous package used.

The addition of a fixed strap is mainly for the convenience of fixing the tripod, but because this is an unadjustable length, the clearance between the handle and the handle is not so great, and the tripod should not be too heavy. At the same time, it can be seen that the printed trip is printed with folds.

The side fasteners need to wear the straps themselves, the packaging does not wear well, and the shoulder strap buckle can be seen on both sides of the diagonal.

On the front side, there is also a convenient place for hanging buckles. In general, I will not hang heavy objects such as a flashlight, a cup, etc.

The outer mezzanine is also subdivided into three layers. I put a lens pen, an ND lens, a black card, and several mirror papers.

After opening the bag, you will see two Velcros and a shoulder strap that you need to put on.

In general, this is what it looks like. It's simpler and looks a bit more academic.

Open the inner layer, you can see the sandwich of small objects, I put in the air, the battery and other small things, which are more suitable for the installation of some necessary gadgets, but also more secure.

The next step is to make reasonable use of the space inside the camera.

If the A7R2+55mm/F1.8 lens and Fuji X100T can lie flat, you can also add a mezzanine Velcro.

If it is replaced with a 16-35 head across the space in the bag is enough, the above DIY hot boots from the handle of the tert-custom, before and have shared a conscience seller, you can customize any you want The pattern may have discounts if you say that you are valued.

Because I personally don't have the need to hold too many things, I just put the camera horizontally. If I put it upright, I can add another layer of Velcro.

After a week of experience, it rained a few times, but because this kind of bag is really difficult to do if it is actually immersed in water, I will only shower in the rain, because the inner layer is thicker and there will not be any rainwater dripping. It is still true.

Now it's almost enough to go out and carry a shoulder bag and dip a dpark. It's enough to wait until you have the money to recharge your faith. After all, the footage of Dafa is too expensive.

I don't know if it's a waterproof material. It's particularly easy to pick up dust, so don't use toilet paper to wipe the surface. You can only wipe it clean with a damp rag.

After all, the price of this bag is relatively cheap compared to many big-name camera bags, plus the appearance is relatively simple and generous, so I can still give it 4 points (out of 5 points)

Can not be considered a giant package of photography, but can be loaded under the A7 + X100T + two lenses is no problem, the appearance is more or less not very waterproof but it is for the often raining Jiangsu and Zhejiang area is excellent, The lining is also very thick to protect the camera from being hit.

The outer material is easily stained, so it needs to be wiped with a wet rag. It will look more comfortable. There are multiple buckles to facilitate hanging other small objects. This is still relatively friendly, if the price is cheaper !

Cable fault types and methods

Whether it is a high-voltage cable or a low-voltage cable, faults often occur due to lines, overloaded operation, insulation aging, or external force damage during construction, installation, and operation. Zhili Electric is one of the professional manufacturers of cable fault testers. This article introduces you to several practical measurement methods for cable fault points so that you can easily find the fault points of cables.

The cable fault is divided into three types: grounding, line, and disconnection. Three-core cable fault types mainly include the following aspects: one-core or two-core contact; two-phase core wire; three-phase core wire complete line; one-phase core wire breakage or polyphase breakage. For a direct line or disconnection fault multimeter can be directly measured and judged, for indirect lines and ground faults, using megohmmeter remote measurement of insulation resistance between cores or core to ground insulation resistance, according to its resistance value can be determined type of failure.

Four ways to find cable faults

1. Sound measurement method: The so-called sound measurement method is based on the sound of faulty cable discharge. This method is more effective for high-voltage cable cores for insulation layer flashover discharge. The equipment used in this method is a DC voltage transformer.

When the capacitor is charged to a certain voltage value, the ball gap discharges the cable fault core wire. At the fault, the cable core wire discharges the insulating layer to produce a sparking sound of “nozzle and nourishment”. In order to bury the cable, you must first determine and mark the direction of the cable. Then when the noise noise is minimal, use an audiophile or medical stethoscope to search for it. When looking up, place the pickup close to the ground and slowly move along the direction of the cable. When you hear the sound of the “zigand and sizzle” discharge, it is the point of failure. Use this method must pay attention to safety, in the end of the test equipment and the end of the cable should be set up to monitor.

2. Bridge method: The bridge method is to measure the DC resistance value of the cable core by two-arm bridge, then accurately measure the actual length of the cable, and calculate the fault point according to the proportional relationship between the cable length and the resistance. This method determines that the error is generally not more than 3m for faults where the direct line or line point contact resistance between cable cores is less than 1Ω. For faults where the contact resistance at the fault point is greater than 1Ω, the resistance can be reduced to 1Ω by increasing the voltage through burning. Below, measure again according to this method.

First, the resistance R1 between the cores a and b is measured, and R1=2Rx+R, where Rx is a phase resistance value of a phase or b phase to the failure point, and R is the contact resistance of the line contact. At the other end of the cable, the DC resistance R2 between the a' and b' cores is measured. Then R2 = 2R(LX) + R, where R(LX) is the a' phase or the b' phase core is faulty. The resistance value of one phase of the point, after measuring R1 and R2, connect the b′ and c′ lines, and measure the DC resistance between the two phases of the cores of b and c. Then, 1/2 of the resistance is each phase. The resistance value of the core wire is represented by RL, RL=Rx+R(LX), and the contact resistance value of the fault point can be obtained: R=R1+R2-2RL, therefore, the resistance value of the core wire on both sides of the fault point The following formula can be used: Rx = (R1-R) / 2, R (LX) = (R2-R) / 2. After the three values ​​of Rx, R(LX), and RL are determined, the distance X from the fault point to the end of the cable or (LX) can be obtained by a proportional formula: X=(RX/RL)L, (LX)=(R (LX)/RL)L, where L is the total length of the cable.

When using the bridge method, the accuracy of measurement shall be ensured. The bridge connection line shall be as far as possible, and the wire diameter shall be large enough. The connection with the cable core shall be crimped or welded. The decimal places shall be retained during the calculation.

3. Capacitance amperometry: When the cable is in operation, capacitance exists between the cores and the core to the ground. The capacitance is evenly distributed.

The capacitance is linearly proportional to the length of the cable. Capacitance amperometry is based on this principle. It is very accurate in the determination of cable breakage.

Measurement steps:

First, measure the value of the capacitance current of each phase of the core wire (which should be equal to the applied voltage) Ia, Ib, and Ic at the head end of the cable.

At the end of the cable, the values ​​of the capacitance currents Ia', Ib', and Ic' of the core of each phase are measured to check the ratio of the capacitance of the perfect core to the disconnected core, and the approximate point of the disconnection distance can be preliminarily determined.

According to the capacitance calculation formula C=1/2πfU, C and I are proportional to voltage U and frequency f. Since the f-frequency of the power-frequency voltage does not change, the applied voltage must remain constant during the measurement, and the ratio of the capacitance current is the ratio of the capacitance. Let the total length of the cable be L, and the distance of the broken point of the core line be X, then Ia/Ic=L/X, X=(Ic/Ia)L.

During the measurement process, as long as the voltage is kept constant, the ammeter reading is accurate and the total length of the cable is measured accurately. The measurement error is relatively small.

4, zero potential method: zero potential method is the potential comparison method, it is adapted to the length of the cable core to the ground fault, using this method is simple and accurate measurement, does not require precision instruments and complex calculations. The principle of measurement is as follows: Connect the cable fault core in parallel with the equal length of the comparison conductor. When applying the voltage E at both ends, it is equivalent to connecting the power at both ends of the two parallel uniform resistance wires. At this time, any resistance wire The potential difference between one point and the corresponding point on the other resistance wire must be zero. Conversely, the two points where the potential difference is zero must be the corresponding point. Because the negative terminal of the microvoltmeter is grounded, and the point of failure of the cable is equalized, therefore, when the positive terminal of the microvoltmeter moves on the comparative lead to the point where the indicated value is zero and the fault point is equal, that is, the corresponding point of the fault point.

Measurement steps:

Firstly connect the battery E to the core wires of phase b and c, and then lay a comparative wire S equal to the length of the faulty cable on the ground. The bare wire or bare aluminum wire should be used. Intermediate connector.

Ground the negative pole of the microvoltmeter and the positive pole to a long, flexible wire. The other end of the wire requires full contact when sliding on the comparative wire. Close the knife switch K and slide the end of the soft wire on the comparative wire. When the microvoltmeter indicates zero, it is the position of the cable fault point.

The large-screen Internet market has a lot of imagination. LeTV and Xiaomi have become bright stars in this market. But it seems that everyone forgets that there are still powerful BATs in this area. After Tencent’s share of Internet TV’s micro whales, it added another 450 million yuan to TCL’s Thunderbird, which is also an investor in micro-whales. Ali family entertainment also relies on Youku to launch a smart TV cooperation alliance. AT has a lot to say . In the future, who is the master of Internet TV?

Ali sets up a smart TV cooperation alliance

AT deeply involved in Internet TV

As a giant of the Internet, Tencent Ali not only invested heavily in the Internet and mobile Internet, but also did not let go in the area of ​​large-screen home Internet.

As far as Internet TV is concerned, Tencent’s Ali is deeply involved in the project of Li Weigang and Li Huaiyu’s micro whale television. Xiao Bian sees from the inquiries of the sky, Microwhale Technology conducted A round of financing in August 2015, and Alibaba, Tencent Industrial Fund, and Chinese Culture Industry Investment Fund were investors, with a total investment of 2 billion yuan.

In May 2016, the registered capital was changed. The registered capital was changed from 200 million yuan to 2 billion yuan. There were four shareholders, namely the major shareholder Chinese Culture Co., Ltd., and the subscribed fund was 780 million yuan, accounting for 39% of the shares; Alibaba (China) Network Technology Co., Ltd. subscribed for capital of 630 million yuan, accounting for 31.5% of the shares, Suzhou Industrial Park Purple Cat Information Consulting Co., Ltd., subscribed funds of 400 million yuan, accounting for 20% of shares; Linzhi Tencent Technology Co., Ltd. It paid 190 million yuan, accounting for 9.5% of the shares.

Microwhale Technology Shareholders Information

As can be seen from the shareholder structure, Ali accounted for 31.5% of shares, second only to 39% of the Chinese culture of major shareholders. The difference between the two is only 7.5%. Tencent also has a certain percentage of shares, close to 10%. In other words, Alibaba and Tencent both have deep access to micro whale technology that focuses on Internet TV, but it is clear that Ali’s influence is even greater.

Perhaps in terms of micro-whales, Ali’s influence is even greater. Tencent believes that the eggs should be placed in multiple baskets. Xiaobian learned a few days ago that Tencent has invested in TCL’s leading Internet TV brand Thunderbird.

TCL Group announced on the morning of July 3 that its subsidiary Shenzhen Thunderbird Technology Co., Ltd. introduced strategic investors Tencent by way of increased capital and shares, and the latter subscribed Thunderbird's newly added registered capital of RMB 20.27 million for RMB 450 million. Yuan, obtained 16.67% stake in Thunderbird Technology after this capital increase.

After the completion of this capital increase, the registered capital of Thunderbird Technology has increased from 100 million yuan to 120 million yuan, Tencent holds 16.67% stake in Thunderbird Technologies, and Thunderbird Technology shares held by Fcalcon, a wholly-owned subsidiary of TCL Multimedia The proportion will be reduced from 54.05% to 45.55%. Upon completion of the capital increase, Thunderbird Technology will no longer be a controlling subsidiary of the TCL Group.

TCL Introduces Tencent as a Strategic Investor for Thunderbirds

In the micro-whale, Ali is the second largest shareholder after the Chinese culture. In Thunderbird, Tencent is a strategic investor introduced by TCL Group, and its influence is second only to the TCL Group. Ali had also been a Thunderbird platform when Thunderbird TV was released, but so far he has not seen any capital cooperation between the two sides.

Occupy the living room with content and system

Why are Alibaba and Tencent keen to invest in Internet TV or cooperate with Internet TV brands? In fact, the reason is very simple, that is, hope that through the Internet TV terminal, put their own content, systems into the implementation of data control and in-depth operation of home users.

Internet TV still maintained rapid growth when the TV industry was in a sluggish state. According to statistics, from 2012 to 2016, Internet TV maintained a high growth rate of 47.69%, 18.43%, 24.44%, and 13.84%. In 2016, domestic TV retail volume exceeded 50 million units, of which Internet TV brands accounted for 20%. In the next five years, Internet TV will continue to develop rapidly.

The advantages of Tencent and Ali do not lie in the terminal, nor will they do their own terminal. The advantage of the two lies in the content and system. Tencent and Ali’s video content resources are abundant. Tencent video and Youku Tudou are the content exporters and operators. In addition, Ali has its own system, Yun OS. The implantation at the operating system level will allow Ali to obtain big data in the living room in order to better tap the living room economy.

Xiaobian notes that Ali Tencent is accelerating its layout in the field of large-screen Internet. Tencent launched Penguin TV, an overall software solution for Internet TV and smart set-top boxes. Penguin TV mainly focuses on video content, and it is open to cooperation in the industrial ecology. Public information shows that it has worked hand in hand with the three authoritative Internet TV licensees, the top ten mainstream smart TV manufacturers, leading intelligent set-top box manufacturers and a number of network operators to build a new living room entertainment eغير مجاز مي باشدystem.

For Ali, he led the establishment of the Smart TV Cooperation Alliance to implement the "TV Eco Inside Project," and supported partners through the Yun OS system and Youku content to dig deep into home entertainment. Haier, Konka, Changhong, Hisense, Skyworth, Sharp, Philips, and Microwhale have already joined the brand. The first batch of 6 new smart TV models using Alibaba Digital Entertainment Platform was officially unveiled last October.

It can be seen that although Internet TV seems to be a competition among terminal enterprises, in fact it is behind content and system operation control. In this regard, Ali and Tencent are veterans. Alibaba Tencent who is not a terminal may be the biggest player in Internet TV.

Superconducting cables have broad application prospects in the occasions where large currents are transmitted over a short distance (such as city center distribution, power plants and substations), and their economic benefits are considerable. The use of superconducting cables to retrofit existing underground cable systems can reduce total غير مجاز مي باشدts by 20%. Therefore, due to its superiority, superconducting cables are a good alternative to conventional cables in the process of upgrading and augmenting urban power grid facilities. According to statistics, the annual demand for cross-linked polyethylene insulated power cables of 10 kV and above in China is approximately 70,000 to 80,000 kilometers. If 5% of its total volume is replaced by superconducting cables, the annual potential demand for superconducting cables will increase. The total volume will reach 3,500 to 4,000 kilometers. With an average of RMB 2 million per kilometer, the potential market is 8 billion yuan. If you increase at a rate of 7.5% per year, the potential market in 2012 will reach 18 billion yuan. If the market share of the product reaches 10%, the annual output value can reach about 1.8 billion yuan. The market for global superconducting cables in 2012 is estimated to be approximately US.7 billion. At present, the research and development level of China's high-temperature cables is far from meeting the needs of new markets. China's technology in this respect lags behind that of advanced foreign countries. Nearly half of the high-temperature cables need to be imported from abroad, while some domestic manufacturers are concentrated in some small factories. Technological development and production capacity are relatively weak. In particular, production and processing are still limited to existing equipment and tooling of cables, and the development of materials has failed to break through the circle of existing cable materials. It is hoped that domestic manufacturers capable of developing high-temperature special cables can assess the situation, develop and popularize high-temperature series cables in light of China's resources, and increase China's level in this technical field to meet the needs of China's high-temperature industries.

It is estimated that by 2020, the total market for superconducting applications in the world will reach 244 billion U.S. dollars, and high-temperature superconducting cables will account for about 5% of the total. As an important part of special cables, high-temperature cables have extremely strong vitality and are in short supply. China imports about two billion yuan from abroad for domestic construction each year. Due to the adoption of high-temperature superconducting materials with high transmission current density as conductors and liquid nitrogen as the cooling medium, high-temperature superconducting cables have the advantages of small size, light weight, low loss, no fire hazard, etc., and transmission loss of conventional power cables is approximately The transmission power is 7%, while the transmission loss of the high-temperature superconducting power cable is only 0.5%. If the energy consumed by cooling is taken into account, the final energy saving will be over 60%; in the case of the same weight and size, the conventional power cable In comparison, the capacity of high-temperature superconducting cables can be increased by 3 to 5 times, the loss can be reduced by 60%, and the weight can be reduced by more than 80%. It is suitable for applications where short-distance transmission of large currents is required, such as urban center distribution, electroplating and electrolysis industries. , power plants and substations. The cable industry has been in a state of vicious competition for a long time. The application of superconducting technology gives cable companies a chance to surpass their competitors and how their development will depend on the capacity of the cable market to absorb.

Pharmacological effects

The role of the nervous system

An analgesic effect: Sinomenine demonstrated positive analgesic effects in experiments with mouse electrical stimulation, hot plate method, and rabbit photothermal stimulation. The dose required for analgesic effect by intracerebral injection is equivalent to 1/2000 of intraperitoneal injection, indicating that the site of analgesia is in the central nervous system; it is combined with propylene morphine and does not appear to antagonize, but instead produces synergy, indicating that it The principle of analgesia is different from that of morphine analgesics. The dose required to produce analgesia is about 10 times that of morphine and has a shorter duration. Continuous use can also produce tolerance, but it is slower than morphine and there is no cross-tolerance with morphine. In combination with promethazine, the effect is enhanced, which is mainly due to the synergy of the central role of the two drugs, and some may also be due to the release of histamine by the promethazine against the sinomenine. When combined, there was no effect on the production and toxicity of sinomenine. Two sedative effects: Sinomenine significantly reduced the spontaneous activity and passive activity of mice, and had no significant effect on the sleep time of barbiturates; it had certain antagonistic effects on strychnine (reduced seizure threshold of strychnine in mice). ) But not against pentamethasine tetrazole. Dogs and monkeys also had significant sedative effects by oral administration of sinomenine 45 to 95 mg/kg. A small dose (5 to 10 mg/kg) prolongs the latency of defensive exercise conditioning in mice and cats. The conditioned reflex partially disappears, and the non-conditioned reflex also disappears in small proportions, indicating that it is primarily for advanced nerve activity. The excitement process has inhibitory effects. Sinomenine also eliminates the irritated reactions induced by electrical stimulation in mice and appears to have a stabilizing effect. Three other effects: sinomenine has an antitussive effect. For mice and cats, the antitussive potency is similar to codeine; for guinea pigs, the potency is only 1/4 that of codeine. Promethazine can strengthen its antitussive effect. In addition, slight emetic effect, no effect on vomiting caused by injection of dehydrated morphine. When rats are given large doses intraperitoneally, there is a certain cooling effect. When the amount of poisoning injected into the rabbit, the body temperature has also declined, but if given repeatedly, can produce tolerance, and body temperature no longer decline. According to reports, it has a local anesthetic effect on rabbit cornea, can be used as a local infiltration anesthetic, but it can also produce tolerance, such as continuous injection, the effect is weakened.

Antihypertensive effect

The total alkaloids of sinomenine have a positive acute hypotensive effect on both anesthetic and non-anesthetized experimental animals (dogs, cats, rabbits, and rats), whether intravenously or intragastrically. The effects are rapid, significant, and long-lasting, but they are administered multiple times in succession. , it produces rapid tolerance. The antihypertensive effect was not related to M-cholinergic nerves or acetylcholine, nor was it due to histamine release. It may be related to its anti-adrenergic and nerve reflex effects. Due to the above-described hypotensive properties, it has no significant therapeutic effect on chronic experimental hypertension in dogs. The acidic extract of Ivy does not affect blood pressure in acute tests in rabbits.

Effect on gastrointestinal activity

Sinomenine often causes mild gastrointestinal adverse reactions to dogs and monkeys; it has inhibitory effects on ex vivo rabbit intestine and guinea pig intestine, and can counteract the deterrence effects of pilocarpine, histamine, acetylcholine, and strontium chloride, but Intravenous sinomenine in dogs and rabbit intestine all caused temporary excitement in the small intestine. This excitatory effect was completely blocked by diphenhydramine and hexahydrocarbamate. Atropine was completely or partially blocked, but both sides were cut off. The vagus nerve does not block. Injection of sinomenine can increase the secretion of gastric juice and its acidity, and no significant change in pepsin activity. Excitatory effects on the gastrointestinal tract are mainly related to histamine release. However, the administration of neotaxine (an antihistamine) failed to suppress the secretion of gastric juice. The acidic extract of sinomenia can stimulate ex vivo rabbit intestines.

Anti-inflammatory effect

Sinomenine has a significant regression effect on formaldehyde and egg white arthritis in rats, and this effect is not observed after the removal of the adrenal gland or pituitary. For normal rats, the content of vitamin C in the adrenal glands can be reduced. After pentobarbital (which inhibits the hypothalamus) anesthesia is lost, the anti-inflammatory action of sinomenine may affect the pituitary through the hypothalamus. Caused by the adrenal system, but not related to the release of histamine. It has a preventive effect on active anaphylactic shock in guinea pigs, but it is worse for dogs. Simultaneously with the antigen, it can inhibit the release of histamine. Trichomonas and Plasmodium also have inhibitory effects.
