Chapter 7 Development of fluorescent lamps Zhenjiang mutation

Hearing that the phosphor was made, Zhang Zhimu hurriedly came to the laboratory of those people who worked on phosphor.

This lab is too messy, with dust everywhere, but there's a room in there, and the environment is better. Zhang Zhimu and Yang Chang followed a few of them into this better room before they dared to gasp for breath.

The leader of this group said embarrassedly: "Mr. Zhang, you see that we are too chaotic here." There is no way, I have been doing it for a long time before and there is no effect, and everyone is not in the mood to clean it up. Developed a bad problem. ”

"Bad things are small things, you work in such an environment for a long time, and your body is finished." Zhang Zhimu said, "In the future, we should try to use equipment as much as possible to reduce the dust from grinding to fly out." That thing can't be inhaled into the lungs and can't be discharged, and silicosis will form, which is very dangerous. At the very least, wear a mask. ”

"Okay, Mr. Zhang! We'll pay attention later. The team leader nodded hurriedly and said.

"You've been working on phosphor for a long time, and now you've finally got it out, and I want to congratulate you." Zhang Zhimu said, "Let's talk about the situation! ”

"Well, we did a lot of experiments with different proportions of apatite with different kinds of other things. Now I have found a formula of apatite plus antimony and manganese, and the luminous efficiency is very high. The team leader said excitedly.

"Great!" Zhang Zhimu said, "With this thing. We can develop fluorescent lamps. ”

"Fluorescent lamps?" Yang Chang asked.

"That's right! Fluorescent lamp. Zhang Zhimu said, "You see, our current incandescent light line is red, and the color of things is not good, isn't it?" ”

"That's right! Wouldn't it be better if we could make a lamp that glows white like the sun's rays and is still brighter? Zhang Zhimu said.

"So you want to use this phosphor as a lamp that emits sunlight?" Yangchang somewhat understood.

"Well, we use a glass tube, which is coated with this phosphor, and the air is extracted, and a little argon is put in it, and then mercury is put in. Due to the low air pressure in the glass tube, the mercury will volatilize into steam, we add electrodes at both ends of the glass tube, and when the alternating current is applied, the mercury vapor will be excited to ultraviolet light, and the ultraviolet light will stimulate the silver light powder. Such light is white light. Zhang Zhimu said.

"Then let's study the fluorescent lamp right away!" Yangchang said.

"Don't worry! "You listen to me," Zhang Zhimu said, "and this lamp needs a high voltage excitation before it can be lit. In fact, this is through a high voltage at both ends of the electrode arc, fluorescent lamp is the arc discharge light. You bring a pen and paper. ”

The team leader hurriedly took out a pen and paper and gave it to Zhang Zhimu. Zhang Zhimu drew them a schematic diagram of an inductive ballast and a schematic diagram of a jumping bubble. Then Zhang Zhimu said: "Let me first tell you how this ballast and bubble jumping work." You see, after the power is turned on, 220V alternating current passes through the ballast, and a high voltage of about 600V is generated under the action of the ballast mutual inductance, which is added to the lamp, the lamp has no reflection, but the jumping bubble on the other side of the lamp in parallel is connected to the 600V high-voltage electricity through the filament, and is added to both ends of the jumping bubble, because the neon bubble inside the jumping bubble can not withstand the high voltage of 600V, it breaks through the neon gas in the neon bubble and emits red light, and emits heat, and the thermal contact in the neon bubble stretches under the action of heat and touches another contact. After contact, the neon bubble is in a short-circuit state, and after the short circuit, the filament of the lamp tube is energized, emitted and heated. Due to the short circuit in the neon bubble, the two ends of the neon bubble are not electrified, and after a while, the thermal wire in the neon bubble cools, shrinks, and the contact is disconnected. Because the thermal wire in the neon bubble inside the jumping bubble is disconnected, the filaments at both ends of the lamp tube can not get the voltage and stop glowing, but the mercury vapor inside the lamp is not cool, and at the same time as the jumping bubble is disconnected, a high-voltage reverse voltage and 600V high-voltage superposition will be generated on the inductance, and this superimposed high-voltage arc emitting light. After the lamp is turned on, the voltage at both ends drops immediately, and the partial voltage of the inductor drops to about 110V. Under the supply of 110V alternating current, the lamp works stably, while the jumping bubble cannot be turned on and emitted due to the voltage dropping to 110V, so the jumping bubble is not moving. At this point, the working procedures of the fluorescent lamp are all completed. If the lamp fails to start once, the bubble will be switched on and off repeatedly until the lamp is working properly. You see, the principle is very simple. The problem is to get the ballast and the bubble jumping right. You can also make red, green, and blue phosphors in the future. Then we can do trichromatic fluorescent lamps. ”

Yang Chang and the team leader have not fully understood what Zhang Zhimu said, but the general idea is clear. Yang Chang said: "Good! Mr. Zhang, we have people now, and we are not as nervous as the people in the past, so I immediately took this group as the mainstay, and then organized some people who had worked in electric lighting, and set up a fluorescent lamp research group to increase the number of fluorescent lamps as soon as possible. Let's take a look at what a white light looks like. ”

These tasks were handed over to Yangchang and them, and Zhang Zhimu was already very relieved. Yangchang and a group of them, it should be said that they are all extremely smart people. After they accept the new knowledge, they can quickly digest and absorb it and apply it flexibly. It's just that their foundation is really poor, otherwise, they will be more able to make a difference. But their diligence makes up for many of their deficiencies.

At present, the discussion on stressing civilization and hygiene initiated by Yaogang is very warm. People suddenly have the opportunity to express their opinions, and it feels very new. Whether it was a radio interview or a literati's opinions expressed in the newspaper, they were all enthusiastic beyond Zhang Zhimu's imagination. However, there are also many pertinent comments. For example, there are still too few public toilets, and garbage bins are not cleaned up frequently. Many other comments were put forward through this discussion. For example, there are too few bathhouses and too few vegetable markets. Because the land in Yaogang is all in the kiln company, some people want to come to buy and sell, but they can't do it without land, and so on. Zhang Zhimu was very happy to see that everyone was beginning to be aware of the master. He wanted to have a meeting and ask everyone to look into this matter together.

Yang Yulin said: "Forget it! You didn't look, but now there are a few people at home, and almost all of them have gone down to join the team. ”

Only then did Zhang Zhimu notice that most of the main leaders of the kiln gang and the cadres of various organs were not in the kiln gang. This time, the task force was led by Yan Boju, and Qiu Laodong, Yan Xing, Li Yan, and Zhang Bengui all followed Yan Boju to join the task force. Moreover, this time, the political leaders of the whole army were also transferred to join the task force. The team conducted a one-month training session at the kiln site. This time, the experience of the previous work of the task force was summed up, and new tasks were also assigned. At the same time, the participants discussed various situations that might be encountered and studied solutions. Through the work team, the cadres have been tempered, and the leaders of the kiln gang have also been tempered. Zhang Zhimu knew that this was a very good working method that could be preserved.

Since most of the leaders were not at home, at the opening ceremony of the Lingshui Bridge, Zhang Zhimu invited Chen Yufeng and Ouyang He, as well as Lu Chengxiang and Lu Bingyi, who felt that the number of people was not enough, and Zhang Zhimu also invited Huang Yukun and Sister-in-law Xu, Yang Yulin, and Red Lady who were unwilling to participate in these lively events. This day caught up with last Sunday, and I brought all the children with me. The opening ceremony was a lively one.

The asphalt pavement and painted bridge looks particularly beautiful. After the lively ribbon-cutting ceremony, everyone came to the bridge, and the reporters of the newspaper kept taking pictures of everyone. Guests took photos in various combinations of different ways and in their own way. Xiaoqing and Xiaohu, as well as Gao Yinfeng and Gao Guixiang and their children, are enough to take pictures today. Happy they ran around and looked around.

After the cordon of the bridge was released, the crowd that came to see the lively crowd almost filled the bridge deck.

Lu Chengxiang's happy round face was sweating, and when he saw Zhang Zhimu, he said: "Mr. Zhang, I'll forget it, we charge one-way." Excluding the management costs, there will be silver left. With the bridge, there will be more and more people and cars passing here. ”

"Okay!" Zhang Zhimu said, "You don't see that in the future, both ends of the bridge will be commercial land." ”

"See!" Lu Chengxiang said, "We are going to build a big market in Qiaodong. Stalls can be rented out in the market. Encourage everyone to run the business. ”

"Huh! In this way, it seems that Mr. Lu will not leak the air! Zhang Zhimu said.

"That's right!" Lu Chengxiang said proudly.

Lu Bingyi came over and said: "Last night, we got two tractors to walk across the bridge together, and it turned out to be no problem at all. The bridge is very strong. ”

"It's good to try it, so we're relieved." Zhang Zhimu said.

At noon, Fan Chengkun and they arranged a sumptuous luncheon to entertain everyone, but this time they did not invite guests from outside, they were all their own people from Yaogang, and everyone was very casual. But suddenly Zhang Zhimu saw that Li Zhi also brought a few people over for dinner, and felt a little strange. Because I didn't see Li Zhi at the ceremony.

Seeing Zhang Zhimu looking at him, Li Zhi hurriedly came over and asked, "Is there something wrong with Mr. Zhang?" ”

"I didn't see you at the ceremony, did you come here to eat?" Zhang Zhimu asked rhetorically.

"Hey! How dare we bother to attend the ceremony! Li Zhi said, "We just eat." Anyway, we have to eat at noon, can we not come here if there is something delicious? ”

"What's going on here?" Zhang Zhimu asked.

"Li Zicheng's point is now a big deal." Li Zhi whispered in Zhang Zhimu's ear, "We didn't serve them before, they were right. We haven't touched them, they thought they hadn't been exposed, and now there are quite a few more. During this time they had some new people coming, and I came over to rearrange it. Rest assured, it's all under control. ”

"**No news?" Zhang Zhimu asked.

"Before the end of the year, I came with a copy of the information on the deployment of the Dashun army, and I have handed it over to Mr. Ouyang. There has been no news after the New Year. Li Zhi said, "I estimate that it will be soon, and I stipulate that if there is nothing to do, I must contact on time." ”

"Good! Get busy! Zhang Zhimu said.

After lunch, everyone went back to the kiln. But Xiaoqing and Xiaohu both want to play at Lingshui Pier for a while. Zhang Zhimu said: "Okay, I'll accompany you." Let them all go! ”

Zhang Zhimu led Xiaoqing and Xiaohu again, as well as Gao Yinfeng and Gao Guixiang to take another turn at Lingshui Wharf. Zhang Zhimu led them to the shipyard for a visit, led them to see the docks of tugboats, sand dredging ships, and large sand dredging ships, and also introduced them to the uses and differences of various boats.

Xiaohu said: "When I grow up, I will come to build a big ship." ”

Zhang Zhimu said: "When you graduate in the future, we will build sea ships. Build the kind of big ship that can sail around the world. However, you still need to learn your skills now. ”

Zhang Zhimu didn't go back at Lingshui Wharf, but Chen Yufeng and Ouyang He were anxiously waiting for him at home.

As soon as Chen Yufeng and Ouyang He went ashore at Yaogang, they were received by the staff officer to the command center, because Li Yan sent back an urgent telegram.

The victory of the Yaogang people over Li Zicheng's naval army was clearly seen by the general sent by the imperial court. He went back and reported to the imperial court officials who stayed in Yingtianfu about the power of the Yaogang people's warships. Although these officials of the Ming Dynasty reported the results of the battle to the imperial court, they were even more afraid of the Yaogang people. After they got together to study, they came to a common opinion that the kiln people were too dangerous here and that they had to be kicked out. However, the warships of the Yaogang people had just helped win the battle, and it was not appropriate to drive them away now. But there is no way for them to do good things, and there are all bad ideas. They studied and decided to inform the Yaogang people that Zhenjiang was an important military place, and warships could dock, but military personnel were not allowed to be stationed on the shore. In particular, when they heard that the Yaogang people had bought a large piece of land in Zhenjiang, they were even more determined not to keep the Yaogang people here.

After Li Mao rushed back to Yangzhou from Yaogang, he arranged for the next one, and rushed to Zhenjiang, he wanted to enclose the place with barbed wire as soon as possible, and then arrange for the army to be stationed. In that case, it's much more proactive. He knew in his heart that the officials of the imperial court, Nan Zhili, would not be indifferent to the infiltration of the power of the Yaogang people, and they would definitely find a way. But he didn't expect that these officials were inefficient in doing other things, but they were very efficient in doing this thing.

Li Mao promised the official who came to issue the notice: "My lord, we are all employees of the kiln gang, and we will immediately notify the family of your notice." You give us some time. ”

When the official was leaving, he said, "Listen, if you don't listen." We're going to put you all in jail, and we're going to send someone to help you move. ”

Li Mao nodded and sent the official away, and immediately sent a telegram home. However, Chen Yufeng and Ouyang He were on the boat back to Yaogang, so as soon as Chen Yufeng and Ouyang He arrived at the dock gate, they were taken to the command center by the staff officers. They arrived at the command center and called the dock, but they didn't find Zhang Zhimu. They had to leave a message to the dock, and when they saw Zhang Zhimu, they asked him to return to the kiln as soon as possible.

However, Chen Yufeng and Ouyang He thought of two ways, one was to send Xiurong to Zhenjiang as soon as possible, and the other was to transfer a regiment from Hongze Lake to Zhenjiang. Because if there is no military force, our people will definitely be squeezed out of Zhenjiang by the officials and soldiers of the imperial court. However, this is the use of the army, will it make the court think that we are going to rebel? So this matter still has to wait for Zhang Zhimu to come back and discuss it.

As soon as Zhang Zhimu and the children arrived at the wharf, the people on the wharf told Zhang Zhimu to let him go back to the kiln as soon as possible, and there was an urgent matter at home. Zhang Zhimu didn't get on the boat and immediately called the command center. Ouyang He introduced the situation to Zhang Zhimu and expressed his opinion.

Zhang Zhimu said: "Immediately order the Xiurong to prepare for sailing." There is also a plan to send another lucky ship over, and let them prepare as well. The troops on the other side of Hongze Lake also hurriedly gathered and prepared to move. I'll talk about the rest when I go back to the kiln. ”

The children are very sensible and know that there is something going on at home, so they didn't bother Zhang Zhimu on the boat.

Zhang Zhimu himself was quiet, thinking about whether this matter was the emperor's intention or the intention of those officials in Nanzhili. Analysis to analysis Zhang Zhimu can not be sure. But that's what the emperor meant, he didn't tell us publicly, besides, we just helped them fight a battle on the Yangtze River, and the emperor shouldn't do this. The emperor still asked us to use the army to go out to support them, and he wouldn't change his mind so quickly.

In any case, warships must not be withdrawn from the Yangtze River, but there is no support base on the shore, and warships cannot stay. So since we have already bought land in Zhenjiang, we must not return it. Now the emperor will not turn his face with us for this matter. He knows that he won't do any good by flipping against us. Even if the emperor wants us to leave, he will persuade us to leave for various reasons. If we don't leave, he may turn against us. Even then it is only possible. In the end, he didn't dare. Because after turning his face, he is not our opponent in any aspect. It seems that it is very likely that those officials of Nanzhili are uncomfortable when they see our hands stretched out to them. If that's the case, you really can't get used to them. This time, we will take the opportunity to help the emperor just after building a base in Zhenjiang with great fanfare. If those officials are not convinced, we will stretch out our hands to Ying Tianfu to see what tricks they have. They can't do it with their hands.

Thinking of this, Zhang Zhimu felt relaxed. After chatting with the children for a while, the boat arrived at the kiln.

Zhang Zhimu asked the children to go home by themselves and took a carriage directly to the command center. When he arrived at the command center, Zhang Zhimu told Chen Yufeng and Ouyang He about the straightened out ideas on the road.

Ouyang He said: "What Mr. Zhang thinks is similar to what we analyzed. Then let's get the ships and armies out right away! ”

Chen Yufeng said: "When you go out, you must pay attention to secrecy. It would be nice to wait until they were all there. ”

"That's right! I asked Li Mao to immediately erect barbed wire fences around our place, build simple sheds, and arrange accommodation for the army. Zhang Zhimu said, "After the barbed wire fence is erected, a big wall should be built around it. This time it was necessary to send not only a regiment of infantry, but also a regiment of artillery. Don't be afraid to spend money to build a big wall, hire as many people as possible, and act quickly. With our strength, they don't dare to do anything, and besides, we are close to the Yangtze River, and they can't block us. ”

"The big wall is to be built according to the fortifications, and there must be enemy towers and forts around it." Ouyang He said.

"Huh!" Chen Yufeng smiled and said, "As long as we tell Li Mao our determination." Li Mao knows what to do, we don't have to think too carefully. At that time, we will have three Fu ships and one steel-hulled warship on the Yangtze River. I'll see who dares to do anything with us. ”

Ouyang He immediately drafted a telegram and sent the decision of the kiln to Li Mao.

Li Mao read the telegram, his tears almost didn't come down, and he sighed and said, "Alas! Finally, I don't have to endure it! ”
