Chapter 66 King Li Chuang Begins to Act The camera begins to be developed

In the golden autumn of October, the kiln gang members who went to various parts of Shanxi to carry out land reform returned to the kiln gang with their work teams. The land reform work in Shanxi has been basically completed. In the process of land reform, there were also landlords who did not know whether they were alive or dead, and some landlords even organized people to fight against the work team by force. Which of them was the opponent of the police sent by Yaogang, the first evil was shot in public, and their families were sent to Baotou to open up wasteland, and all property and land were confiscated.

When there were a few incidents like this, the kiln people immediately dealt with them with an iron fist, and then carried out a lot of publicity through radio and newspapers. The landlords who were not convinced had to face the reality.

Although various localities have suffered floods again this year, the water conservancy and flood control facilities in Shanxi have been very well done, and the middle and lower reaches of the Fen River, which are very prone to flooding, have not been affected this time. Shanxi ushered in another bumper harvest year.

Although the water in the Huaihe River area this year is not small, because there is no water from the Yellow River to the south, and there is already a small river channel at the mouth of the Huaihe River, Tang Jingyao in particular is very effective in commanding from the front, and the disaster area in the Huaihe River basin is much better than last year. In addition, this side is also very well prepared, and hundreds of thousands of disaster victims who are willing to emigrate will be quickly resettled.

What made Lu Chengxiang happiest was that the grain in the Hetao area was another bumper harvest. Because the cultivated land has matured after several years of cultivation and sufficient chemical fertilizer, grain production has increased substantially.

Zhang Zhimu gave Zhou Yuji a suggestion that those cooked lands can be cultivated by rotary tillage, and the effect will be better without deep ploughing. At that time, they couldn't accept it, so Zhang Zhimu had to let them try. Because in his previous life, Zhang Zhimu heard about such a thing. When a company of the Heilongjiang Agricultural Reclamation Corps was farming, it found that the seedlings planted on the land that was used as a grain field last year were strong outside the roots. Originally, the ground had to be crushed and dried on the ground, and the ground had to be compacted and hardened with a mill before it could be used to play on it. The seedlings grown in such land are exceptionally strong, which subverts the previous understanding that the deeper the land is ploughed, the better.

Because Zhang Zhimu spoke, Zhou Yuji and they chose a piece of land on the Hetao side for testing, and found that it was indeed a lot of grain from rotary farming. The land cultivators are more practical, and those who have been cultivated for two years and do not need to be deeply ploughed are cultivated by the method of rotary tillage, and a lot of grain is really harvested. This is also Zhou Yuji's side now has a lot of tractors, and they have the conditions to carry out rotary tillage operations. Thanks to the large number of tractors, the area of land cultivated is increasing every year. However, a lot of manpower has been liberated, so many workers have been supported by Li Dong.

Another thing that made Zhang Zhimu happily unable to close his mouth was that Xiao Hongyu gave birth to a son. This is not just something that Zhang Zhimu is happy about, he talks about it all day long. Not to mention Zhang Zhimu's influence, Xiao Hongyu's reputation is no less than Zhang Zhimu's.

On the Fujian side, Li Zicheng and Zheng Zhilong went to Quanzhou to meet Fan Chengkun and studied together the matter of attacking Annan's defense port from sea and land. Fan Chengkun has long had this meaning, and they hit it off.

It turned out that Fan Chengkun took over Zheng Zhilong's fleet and reorganized the original specialized armed fleet.

Zheng Zhilong's fleet has a number of specialized armed ships, and many captains are former generals of the Ming Dynasty. After careful examination, Fan Chengkun retained the captains who could use them, trained them, and at the same time assigned them deputies and telegraph operators, and replaced their bulky cannons with infantry guns that could shoot at direct fire. In this way, Zheng Zhilong's original combat effectiveness of the warship has improved a lot. The treatment of those captains is also completely implemented in accordance with the treatment of the captain of Yaogang, but the discipline is stricter than before.

These captains didn't expect the kiln people to take them in and give them such good treatment. In fact, most of these are not bad for money, and what they care more about is that the kiln people agree to send their children to study in the kiln. Now here in Fujian, those big families, if there are children in the family to go to the kiln to study, it is a great honor. Those who used to go to Yaogang are now back, and they are all officials at all levels, which makes the jealous eyes of the Ba Min father red.

Fan Chengkun and Mu Yi had time to study tactics with these captains, especially the tactics of steam ships and sail warships in the future. After contact, the relationship with everyone has also been pulled in. When these captains knew that Li Zicheng's army was going to withdraw to Annam, they proposed to Fan Chengkun that they should be sent to Annam by sea ship. They all said that with our steam warships, it would be easy to take the port of Haiphong. We are very familiar with Haiphong Port.

Fan Chengkun was also very moved by this suggestion, so he also sent a telegram to the command center to make this suggestion. What he didn't expect was that Zheng Zhilong also put forward this suggestion very seriously in Yaogang, and the Yaogang Command Center basically accepted this suggestion and suggested that they refine their action plan.

When studying these issues in detail, Zheng Zhilong and Li Zicheng saw how the kiln gang people worked. They are all serious and straightforward about the kiln people. The kiln staff carefully checked every piece of information, and the assigned tasks were very clear, and there were several plans for each thing. It can be thought through, and there is absolutely no ambiguity. And the tasks are all put on paper. The plan is very detailed, but it is not rigid, leaving room for all sorts of leeway.

At the same time, the mountain jungle army of Yaogang had set up several large camps near the Lingqu in Xing'an Town, Guilin. Li Zicheng's army had already begun to transport them here by water from Fujian and Zhejiang by tugboat. They followed the canal into the Yangtze River, upstream from Dongting Lake, into the Xiangjiang River, and to Xing'an Town.

Such large-scale transportation is a great test for the transportation capacity of the kiln. The Yangtze River is filled with barges full of soldiers, and these fleets sail up the river day and night. Fortunately, the living facilities on the ship are very complete, and the food is sufficient. These soldiers, who had endured all kinds of hardships, did not feel much sin. It's much better to sit in a ship than to march on two feet.

Zhang Xianzhong's return to Sichuan this time is much more relaxed than when he came, not only in a relaxed mood, but also much more relaxed on the road. Due to the effect of insisting on sand dredging, their group was able to take a passenger boat to Xi'an, where they changed to a small boat to Chencang (Baoji). There was a convoy of cars for Zhang Xianzhong, and they took the car along Chencang Road directly to Hanzhong. The materials prepared by the kiln people for Zhang Xianzhong this time had already been transported to Hanzhong. Among them were 10,000 muskets prepared for them, most of which were produced by surprise for them. There are also many hands **, 150,000 sets of military uniforms.

In Hanzhong, seeing the materials piled up in the big warehouse, Zhang Xianzhong couldn't close his mouth. The warehouse guard said to Zhang Xianzhong: "King! You guys take a count as soon as possible, and we'll be on the road right away. There has been no rain recently, and the water on the Jialing River is stable and just right. ”

"Good! Wang'er, hurry up and take inventory. After ordering, it will be shipped immediately, otherwise it will be difficult to transport these things into Sichuan without being able to take the waterway. Zhang Xianzhong understands that now the channel of the Han River into the Jialing River through the Heihe River has been dug through, and the goods can be transported to the Jialing River by small boats, replaced by slightly larger boats, and when the water is stable, the goods can be transported down the river into Sichuan. Otherwise, I don't know how much effort it will take to go over the mountain and walk the plank road. Now the Yaogang people are building the first barrage dam on the Jialing River, and the water level will be raised in the future, and the water flow under the dam will be stable, so that the goods can be transported into the Jialing River by large ships, and the goods can be easily transported into Sichuan through the locks. In the past, the reason why it was difficult to sail on the upper reaches of the Jialing River was that the water level changed drastically.

Thinking of this, Zhang Xianzhong once again admired the people of Yaogang. When the Hutuo River passenger generator was connected to the grid for power generation, Zhang Xianzhong went to attend the ceremony, and he knew how difficult it was to build a dam. If he hadn't seen it with his own eyes, he wouldn't have believed that there would be such a majestic dam. I don't know what the first dam on the Jialing River will look like, but it is said that the width of the dam is much smaller than that of the Hutuo River dam.

Zhang Xianzhong explained the matter to Sun Kewang and them, and did not stay in Hanzhong for long, so he couldn't wait to take a boat to the Jialing River dam construction site. He wanted to see how the potters built the dam.

When we arrived at the dam site, although the conditions here were not very good, there were already a lot of construction workers gathered here, and the surrounding area of the construction site almost became a town. When Zhang Xianzhong took a boat through the Heishui River, he saw that the boats were almost next to each other. The construction site is full of construction scenes, and workers rotate day and night to carry out construction.

The person in charge of the construction site knew that Zhang Xianzhong was coming, and his family had sent a telegram to inform him that he should take care of him. Therefore, they arranged a board room with bathing equipment for Zhang Xianzhong, which made Zhang Xianzhong very satisfied, he did not expect that there would be such a place to live on such a construction site. When he arrived here, Zhang Xianzhong washed up and slept beautifully, got up at dawn and ate something, so he asked people to take him to the construction site to see.

The person in charge of the construction site took Zhang Xianzhong to the mountain on the shore of the construction site, from here you can overlook the panoramic view of the dam construction site, Zhang Xianzhong was very satisfied with this viewing angle, and carefully watched the construction site with a telescope.

The location of this dam is very well chosen. The Jialing River, which flows from north to south, is divided into east and west rivers by an island formed by a few large boulders in the middle. The whole river is in a valley. The Yaogang people were very clever and first built an earthen dam on the east side of the river to block the river and started to build a cement dam here to make the west river a diversion channel. After the construction of the east dam, the earth dam was excavated and all the gates of the dam were opened for diversion. The other side of the river channel on the west side was blocked for the construction of the east dam, and the two-stage locks were built on the east bank of the river.

Zhang Xianzhong asked, "When will your dam be fully completed?" ”

"It will take two years at the earliest." The person in charge of the construction site replied.

"Oops! With so many people working together, it will take two years, how much silver does this cost? Zhang Xianzhong sighed.

"Huh! This reservoir dam was piled up with silver. However, after the dam is completed, the waterways of the Han River and the Jialing River will be opened, which will greatly improve the transportation on both sides. Passing ship charges are a lot of income, and the income from power generation is even greater! ”

"Yes, yes! I watched the Hutuo River generate electricity, and at that time they calculated an account, and it was simply silver. Don't look at the money you spend now, and you will be the same here in the future. Zhang Xianzhong said.

"King! Have you ever seen the Hutuo River Reservoir for power generation? Can you tell us what it looks like? ”

As soon as Zhang Xianzhong heard that they had never seen the reservoir power generation in the reservoir project, he came to the spirit. It is the spectacular introduction of the power generation scene that I even said by analogy!

After the comparison, Zhang Xianzhong asked, "Fuck! Lao Tzu looked at it, and didn't bother to ask, why did the water be thrown into the air and draw a flower falling after it came out of the dam? Just to look good? ”

"No, as you know, the impact of water leaking out of the dam is very large, and the bottom of the general cement stone dam can not resist its impact for a long time, in order to reduce the impact, we have to take energy dissipation measures, that is, to reduce its impact force. When the water is thrown upwards and dispersed, the air creates a lot of resistance to them, and their speed goes down, and the impact of falling again is not so great. But the water released in this way is really beautiful! ”

Zhang Zhimu took the time to have a few face-to-face discussions with Yang Chang and the people in the team who were engaged in computers, and they had already entered the state a little, and when they saw that they had drawn the future computer block diagram, they knew the rest of the matter, and they needed to be given time to study it slowly.

After the envoy from Liaodong left, Zhang Zhimu closed the door and prepared for a few days, and began to explain the principle of the camera to the team that had developed the display before.

The old-fashioned camera was only a simple study when I learned the principles of TV in school, and the most contact after graduation was the CCD camera, so Zhang Zhimu also took a lot of effort to prepare the principle of the camera course, and the specific parameters could not be said at all.

To put it simply, a camera is a device that turns the light image of a scene into an electrical signal. The structure is nothing more than three parts, one is the optical part, one is the photoelectric conversion part, and the other is the circuit part.

The optical part is not too much of a problem now due to the optical basis of film and camera lenses.

The key to the camera is the camera tube that converts the light image into an electrical signal. The function of the camera tube in the television transmission system is to divide the image of the camera into a number of small units (pixels), and sequentially convert the brightness of each pixel into an electrical pulse signal proportional to it. This electrical pulse signal is easily transmitted and can be reproduced into an image of light when transmitted to a television or monitor. The camera tube is mainly composed of photoelectric conversion (photoelectric conversion and storage part) and electron beam scanning system (reading part). The photoelectric conversion system uses photoelectric emission or photoconductivity to convert the light image of the scene taken by the camera lens into the corresponding potential distribution map on the target. The scanning system scans the electron beam across the target, converting this potential profile into an electrical signal, line by line, point by point.

For the sake of simplicity, Zhang Zhimu introduced the video tube of the photoconductive target. The conductivity target is coated with a layer of antimony sulfide on a glass screen, and a 10-volt DC voltage is attached to this conductivity layer. When the conductive target is illuminated, the conductivity increases, which increases the charge of the conductive layer, that is, the potential increases. The amount of potential rise corresponds to the intensity of the illumination, so that the optical image of the incident light on the conductive target surface becomes the charge image on the other side. Using an electron gun to accurately aim at the point on the target pole and scan the target surface, also known as electron scanning imaging is image plane scanning imaging. The point on the target surface takes electrons from the electron beam so that the target reaches zero potential. The number of electrons in the electron beam ejected from the electron gun is fixed, but the number of electrons absorbed at each point of the target surface is different according to the potential of each point, and the remaining number of electrons returned forms an image signal, that is, the bright spot of the image, so that the potential of the corresponding point on the target surface is high, the number of electrons absorbed from the electron beam is more, and the number of electrons returned is less; Conversely, the number of electrons is high. Thus, the number of electrons returned reflects the degree of darkness of each point on the image.

By controlling the field rate and frame rate of the scan, the video signal can be synthesized. This video signal is sent to the monitor, and the original optical image can be restored.

Zhang Zhimu can explain these principles to everyone, that is, to point out the ideas and methods to solve the problem, but to use physical objects to achieve these, they need to do a lot of work. It is also necessary to see the light after countless failures, as before. Fortunately, these wonderful people are more than willing to take on such a challenge. Take pride in doing this kind of work and enjoy it.

Zhang Zhimu finished telling them, and during the discussion, one of them asked: "Mr. Zhang, what is the effect of our kind of camera?" ”

"So be it! I'll give you an example, we are building a power plant in Hankow, and I'm concerned about the situation there. If there's a camera over there, if you can also send the video signal from that camera back to the kiln, I can see the image through the monitor here. Is this useful? In addition, our current news reporters basically record the situation on the scene in writing, and some use tape recorders. In the future, let's say they all use video cameras to record the situation, with sound and image. Each of us has a monitor in our home, just like we have a radio, and we can see the image and hear the sound, so what will it be? ”

Zhang Zhimu saw that everyone was a little stunned, and said: "Now the cost of filming film is too high, in the future, we will use the camera to shoot a small movie, and then transmit the signal to every household, how good will it be for everyone to drink tea and watch a small movie at home?" ”

Zhang Zhimu's words obviously mobilized everyone's emotions. Someone asked: "Mr. Zhang, we all believe that what you said can be realized, but when will it be?" ”

"Haha! I don't care if I say this, when you get things out, when can you start to implement them. Zhang Zhimu said.

Zhang Zhimu's words caused another burst of laughter, and this time they knew that their dreams were to be realized by them.
