Chapter 961

Fan Keqin went on to say: "So it is very necessary to be vigilant at all times. How is it? Have you finished checking the secret marks? Have you been passive?"

Jiang Bin and Du Shengli did not answer immediately, but squatted down and continued to look at a certain place on the ground.After careful distinction, the two looked at each other and nodded at the same time.Standing up, he said, "Virgo, no one has touched you."

"Okay." Fan Keqin said: "Then let's see how the results of the experiment are."

Hearing this, Jiang Bin and Du Shengli first looked into the four timers through the surface of the water, then fished them out, and looked again.Jiang Bin took one of them and said, "Record, No. [-] timer did not find any abnormalities such as internal water storage." Then he glanced at his watch again, then looked at the time inside the timer, and continued : "There is no problem with the operation, and the deviation is about half a minute, but considering that there is a certain fault tolerance rate, it is really a normal situation."

While he was talking, Du Shengli was holding a small notebook beside him and began to record a little bit.

Jiang Bin put down the No. [-] timer, picked up the next one, looked at it again, and said, "No. [-] timer, there is water seepage inside." Then he glanced at his watch again, and continued: "But since It has been in the water for more than eight hours, so far, the operation is normal, there is a deviation rate of one to two minutes, and the fault tolerance rate is still within the normal range..."

One of Jiang Bin observed and the other recorded, and quickly completed the experimental steps with four mechanical timers for water seepage test.The end result was that, for one of the timing devices, no water seepage was observed.Of the remaining three timers, two of them had accumulated water.One can already see the fog inside.In other words, there were three-quarters of the timers, water seepage occurred.

However, after soaking in water for eight hours, although there is a relatively high water retention situation, the operation of these four timing devices is all normal.

In fact, the main reason for this is that the time is still short, and these timing devices are all mechanical. Although there is already water in it, it is impossible for failures such as rust and death to occur immediately.This requires a process, so the final experimental results show that there is no problem with the timing effect of these mechanical timing devices at least within eight hours.

Fan Keqin said: "This is a water basin. Considering the actual needs, we may be in seawater at that time, and the seawater is about three meters deep. It is completely different from now. So I personally suggest that you go in the river. Also do an experiment, at least the depth can meet the requirements. Get as close to the actual environment as possible, and see how long these timers can still operate normally.”

Du Shengli said: "Yes, we did this experiment today."

Fan Keqin nodded and asked, "Where are those mines? What's the matter?"

Du Shengli replied: "In addition to the original charge department, there are four water injection tanks, and Jiang Ge and I placed TNT. After entering the water, I measured it. When the mine snorkeling returned to zero, it was directly [-] meters underwater. About. Therefore, Brother Jiang and I adjusted the depth setting device repeatedly in detail, and finally found that when the depth setting is at two meters, the actual depth is three meters below the water surface."

Jiang Bin added next to him: "For the sake of accuracy, we also used four mines and conducted experiments in a deeper section of the river. Indeed, as Shengli said, after the four cabins were directly installed with TNT , when the depth is set at two meters, the actual situation is to snorkel about three meters below the water surface. This cannot be wrong.”

Fan Keqin said: "Very good, this is very important." After he finished speaking, he thought for a while and said, "Have you researched the mine trigger device?"

Jiang Bin nodded and said: "I have studied it. The trigger device of the mine is similar to the firing pin model. It is enough to destroy the linkage lever inside it, but the trigger device of the mine is a bit too much, and it is troublesome to destroy it. It's just stupid work."

"Well." Fan Keqin said: "Okay, in a few days, I will find a few brothers with strong diving skills, and you will teach them how to use mines. As you just said, isn't the timing device double-safety? You will learn how to set the time by hand. And they still need to practice, so you'd better dismantle the charge part of a sea mine, detonator and so on. I will arrange for them to conduct special training in the water."

"Understood." Du Shengli stood up and said, "These are not complicated, and they will be done soon."

Fan Keqin said: "Okay, you guys continue."

Next, Fan Keqin looked at the two people's busy work here.They also adopted double insurance for the detonators in the mines, so that if one of the detonation systems fails, the other detonation system can also ensure the explosion of TNT.

After watching for more than an hour and nearly two o'clock, Fan Keqin couldn't stay here all the time, so he went out directly, took his bodyguards, and drove back to the security bureau again.

Zhuang Xiaoman followed him into the office, put the file bag on the table, and said, "Director, all the team leaders and captains acted very quickly. According to your request yesterday, all the lists have been submitted."

Fan Keqin said: "Okay, let me take a look first."

After Zhuang Xiaoman went out, Fan Keqin took out the list from the file bag and began to read it.This list is not a single name, and it's over.How about the water quality, how many meters you can dive, and how long you can hold your breath underwater, all must be reflected.

Fan Keqin finally selected the twelve best water-based ones.Then he looked at another list, and there were many more people on this list, all of whom were from the new field team and investigation department that had joined in the last half month.

The reason why Fan Keqin wants to use a large number of newcomers this time is because these people are all new faces, especially for Guangzhou, they must be new faces.These people, Fan Keqin, still had to be used as an insurance policy, and they had to be commanded temporarily. If everything went well, they wouldn't even be needed.But it's impossible for Fan Keqin to let them go there and do nothing, just travel.

Fan Keqin looked at the list in detail and selected twelve people again.So the person with the best water quality was selected before and joined together.After reading it again, he stretched out his hand and pressed the buzzer, and said, "Xiaoman, come in."

After Zhuang Xiaoman came in, Fan Keqin handed her the list and said: "These people, let the captains investigate secretly and quickly again, and let the captains and team leaders report to me individually after the investigation."
