Chapter 109: The Roar of the Train Wireless Communication

After contact with Li Yan, Zhang Zhimu had a good impression of him. However, Zhang Zhimu also faintly felt that Li Yan and Li Zicheng's brothers were not social, and they couldn't get Niu Jinxing and Song Xiance their reasons. Li Yan was a junior sergeant in the middle of the year, arrogant and arrogant, and in the ranks of that peasant army, those peasant brothers were even more difficult to tolerate a spiritual aristocrat like him. There is also the lack of character of Li Yan, who is not good at being flexible, and the kind of intellectuals who admit reason. Sometimes these problems may not be a problem in other positions, but when a high position can affect others, it may be a fatal problem.

However, Zhang Zhimu and Li Yan communicated very well, and Li Yan also felt that he had met a bosom friend, and the two talked a lot. On this day, Zhang Zhimu and Li Yan sneaked to the construction site of the Yaogang Hotel together, and saw that it was in full swing.

Zhang Zhimu said to Li Yan: "Li Gongzi, don't look at our building, it's just a hotel in our kiln gang. But it can use almost all the high-tech things in our kilns. It will also be the tallest building in our kiln. ”

Li Yan's mind was obviously not here, his mouth was coping, but his eyes were elsewhere, and Li Yan, who couldn't help it, said, "Mr. Zhang, you can arrange something for me to do." I know I still have a lot to learn. But I can also work and study at the same time. ”

Zhang Zhimu did not answer Li Yan's question directly, but asked: "Li Gongzi, what do you say is the most important preparation before building such a building?" ”

"That must be a blueprint, right?" Li Yan replied with some hesitation.

"By the way," Zhang Zhimu said, "if we want to build a new society, we also need a design plan." What is the blueprint for the new society of the future? ”

Li Yan thought about it, but still shook his head and said, "I don't know." ”

"I'll tell you," Mr. Zhang said, "that's a legal system." ”

"Mr. Zhang, you're right. There is a society that has a law. Li Yan understood what Zhang Zhimu meant.

"We have some officials in Yaogang who used to serve in the three legal departments of the imperial court. No matter how short of officials we are in the kiln, I have not released them to be officials. I want to leave them to organize the drafting of our future laws. Of course, a complete film cannot be completed at once, and it also needs to be perfected in the process of use. I want to ask Li Gongzi to come forward to preside over this work, I don't know if Li Gongzi is willing? Zhang Zhimu turned to face Li Yan and asked.

Li Yan didn't expect that Zhang Zhimu would hand over such an important matter to him, and hurriedly said: "Oh, I'm afraid it will be difficult for me to take on this heavy responsibility, Mr. Zhang." I'm better suited to do a little bit of specificity, and you're talking about something too big. ”

Zhang Zhimu said: "Li Gongzi, you are right. It's such an important thing. So I'm not just saying that we need to have someone responsible to take care of this. Not to mention the vastness of the work in this matter, what is more important is how to implement the goal we are striving for in the form of law through the form of law. This is not something that the average person can afford. I think Li Gongzi is up to the task. However, Li Gongzi, we have time, you can think about this matter carefully, and you don't need to answer me in a hurry. ”

Li Yan said: "This matter is too big, Mr. Zhang, let me think about it." ”

"Okay, there's no hurry." Zhang Zhimu said: "I have sent someone to get a set of laws of the Ming Dynasty from the imperial court, and there are many things we can refer to." I think the most important thing for us is to implement the big things like how to elect leaders through elections and how to make the judiciary independent. Many of the torture and shackling systems of the previous dynasty had to be abolished. In particular, such matters as equality between men and women must be enacted in the form of law. There are some specific methods, we can experiment in Shanxi to see what works and what doesn't. We must not take things for granted. ”

Li Yan said: "Mr. Zhang is too right to say this. Let's talk about elections. I don't think it's easy to implement, those people are used to being slaves, you let them choose their masters, and they don't do it. If we give them ballots, they will all be able to eat them in exchange for baked cakes. In particular, we have many places, even in the Ming Dynasty, the officials of the imperial court could not manage, and the clan patriarchs had the final say. How dare the people there not choose their chiefs? ”

"Yes! There is still a long way to go for the people to awaken and have a sense of democracy. But we can't wait for the people to become democratic. Our task is to think about everything. Zhang Zhimu said, "Our laws also need to protect the right to vote for citizens who are not granted." Strict sanctions should be formulated for those who bribe voters and threaten to deceive voters. ”

Li Yan said: "There is one thing that I have never been able to understand. Starting from Taizu, our Ming Dynasty spared no effort in governing corrupt officials, and I don't know how many people cut off their heads, peeled their skins, and cramped, so why can't they stop corrupt officials. ”

"I think this is very complicated," Zhang Zhimu said, "One is that there is no effective mechanism to check the power of officials, and power without supervision will inevitably lead to corruption." The other is institutional. Let's talk about the beauty in front of us. The magistrate there is a good official, but his little money is not enough to give gifts to his boss, you say that he wants to survive, let alone be promoted, isn't he corrupt? So you have decided in the system that officials can't be corrupt. Do you want to let the officials be corrupt? And the Yulu of our Ming Dynasty officials is generally low, you see that the Yulu of Zhixian is about the same as his coachman, do you say that this is not good? ”

"It seems that Mr. Zhang has long considered this."

"Yes, but it's not well thought out. So I hope to have a strong team, calm down, and think about it. What can be done to avoid such a thing. Zhang Zhimu said.

Li Yan was very moved and said: "Mr. Zhang, we have gathered a group of people here in Yaogang who really think about things for the people, and I feel very lucky to be here." The things you want to hand over to me are so big that we are not mentally prepared. You asked me to think about it. ”

"Okay, no hurry!"

Zhang Zhimu returned to the office, and Yang Yulin complained: "Look at you, you don't squeak anywhere, I called you everywhere, but I said I wasn't there." ”

"Hey! If only I had a mobile phone. Zhang Zhimu said: "Why is something so urgent? ”

"Yangchang is here, saying that he has a great happy event to tell you." Yang Yulin said, "It's in your house." Also, what kind of mobile phone do you say? ”

"You'll find out later." Zhang Zhimu was happy in his heart, "It's time to talk again." ”

Seeing the wooden box brought by Yangchang, Zhang Zhimu understood a little in his heart, "How did the wireless transmission and reception get done?" ”

"Mr. Zhang, you are so wise. You can see it at a glance. "Yangchang and Zhang Zhimu have been together for a long time, and they are not so restrained.

"Then let me open my eyes!" Zhang Zhimu said.

Yangchang and the others hurriedly got up and connected the power supply and turned on the switch.

Yang Chang picked up the phone again and wanted to call his laboratory, asking them not to put the phone on and turn on the radio. The radio stations on both sides have been warmed up for a period of time. From the phone over there, Yang Chang heard their voices saying "Hey, hey". But only a small sound could be heard on the radio here. Yangchang's sweat came down a little and said, "When we came, we were all in tune well." I've also said again and again, don't move, don't move. What's going on? ”

Zhang Zhimu said: "It's not a problem, you can just adjust it again." ”

Yangchang originally wanted to show Zhang Zhimu a result directly, and he didn't want to adjust it here, but there was no way. He had to slowly adjust the knob of the variable capacitance. Just pick a little. The sound of "Hey, Hey" came out of the radio.

Yang Chang carefully adjusted it for a while, and his voice was very clear.

Zhang Zhimu said: "Okay, Yangchang congratulates you. Your lab is at least three or four hundred meters from me. It seems that there are no problems with communication. If you want to make a duplex, use a transceiver on each side, and choose two different frequencies, it is a full-duplex wireless phone. You can also use a frequency point to switch between sending and receiving, and make it into a half-duplex, just like a telegraph. ”

Yang Chang said: "We can also do wireless telegraphy in the future." ”

"Yes, the same radio station, which is used to send telegrams, is much longer than a voice call. Because the signal requirements of telegram are not as high as those of voice. Zhang Zhimu said.

"Let's try to receive and receive telegrams when we get back." Yangchang said.

"Do you know why you have to tune up the radio station when you get here?" Zhang Zhimu asked.

"What am I?"

"This is possible because of the change in the parameters of your receiver station, and there is also the possibility that there may be changes in the transmitter over there. If you want to have a very stable frequency, you need to use a crystal as an oscillator. Zhang Zhimu said.

"Crystal oscillator?"

"You can find some pure crystals, grind them into thin sheets, and then plate them with metal on both sides and weld out two pins that are attached to the oscillator. The oscillation frequency will be very stable. Zhang Zhimu said.

"What's the point?" Yang Chang asked.

Zhang Zhimu patiently explained: "There are many materials with piezoelectric effect. That is, when you apply pressure to this material that has a piezoelectric effect, the material generates a voltage. On the other hand, when you add voltage to this material, the material will also be deformed. If you apply a voltage at a frequency close to one of the natural frequencies that the crystal has, then the crystal will oscillate at that frequency. And this natural frequency is related to their physical size, that is, there is a frequency of what kind of size there is. This frequency is very stable. ”

"So how the hell do you use this crystal?" Yang Chang asked.

"There are many types of crystal oscillation circuits. The simplest thing is our capacitive three-point oscillator, you just replace one capacitor with a crystal. After Zhang Zhimu finished speaking, he drew an equivalent circuit of a crystal for Yangchang.

Yang Chang looked at it and said: "If it can really be like what Mr. Zhang said, we will arrange a few people to specialize in the production of crystal oscillators." ”

"You have to arrange for someone to do it now. Because it's something you have to do sooner or later. In the future, high-precision oscillation will be inseparable from it. Have you ever thought that there is a very important application for a high-precision oscillator? Zhang Zhimu asked.

Yang Chang thought for a moment, and suddenly said, "Clock? ”

Zhang Zhimu said: "By the way, with high-precision crystal oscillators, we can develop high-precision clocks. In this way, the accuracy of the clock is not affected by the position in the ground, nor is it affected by bumps and vibrations. Isn't it possible for us to use them with marine clocks? ”

Yangchang said: "Yes, I will arrange for someone to do this when I go back." This thing is amazing. I'd like to see what the piezoelectric effect looks like. ”

"Yangchang, the experiment is done. Your task is to make a shortwave telegram. This is what we need so much right now. I won't say much more about its significance. Zhang Zhimu said to Yangchang very seriously.

"Don't worry, Mr. Zhang. I know how heavy it is! Yang Chang replied very seriously.

At this time, Zhang Zhimu thought about using radiolocation again, but then he thought about it, there were too many things involved in this matter, and it was necessary to set up radio transmitters on several coasts. Let's talk about this later, anyway, it's still early to go to sea.

The time came to July of the seventeenth year of Chongzhen. It's the hot summer season. The work of the kiln gang has also ushered in a **.

Through the efforts of Yangzhou and Xuzhou branches, a large amount of summer grain was rushed back. The tugboat of Yaogang dragged the barge several times before it was transported back. With the grain kiln, the waist pole of the kiln gang is harder.

Another thing that makes the people of Yaogang feel more excited is that the railway from the smelting yard to Yaogang has finally opened.

When the train came out of the locomotive factory in the smelter, the front of the locomotive was covered with red flowers, and with the whistle of "woo", the steam locomotive slowly drove onto the steel rails leading to the smelter. In this test run, a passenger car was dragged behind the front of the car. Zhang Zhimu and Lu Bingyi personally accompanied them in the carriage, which was also to cheer for the drivers who tested the car. The locomotive was on the road for the first time, and Zhang Zhimu's requirement was to seek stability. So the maximum speed of the locomotive is twenty kilometers per hour. Even so, it didn't take an hour for the locomotive to travel 30 miles from the kiln to the smelter. Everyone talked and laughed in the carriage, thinking that it would be there in a while.

The kiln gang saw off the lively, and the smelting field was also very lively. Here is also the flying of colorful flags, gongs and drums. The people here in the smelting yard are more looking forward to the opening of the train than the kiln gang.

The locomotive stopped at the metallurgical station, Zhang Zhimu and Lu Bingyi got off the train, came to the locomotive, congratulated the locomotive waiting for the opportunity and the development personnel of the locomotive factory, and congratulated them on the successful test run. At the smelting station, Zhang Zhimu said hello to Liu Baoxue and others in the smelting field, and then took the train back to Yaogang. On the way back, the locomotive was a little bolder, and the train accelerated to 30 kilometers per hour. The train quickly returned to Yaogang.

After Zhang Zhimu got off the train, he instructed the driver and locomotive development personnel to run out of the locomotive's extreme speed on the premise of safety. At the same time, it is necessary to test the train back and forth many times, and the hidden dangers must be eliminated.

What Zhang Zhimu didn't expect was that the locomotive test personnel transported the steel of the four wagons from the smelting yard to the kiln gang the next day. Each wagon was loaded with twenty tons of steel.

In the freight yard of Yaogang Wharf, they used tower cranes to lift the steel directly from the train, put it on the barge, and transported it directly to the shipyard by barge.

Zhang Zhimu knew that they really wanted to show the power of train capacity.

It was the first time that the Kiln Gang Weekly published a photo of the locomotive in the newspaper with a front-page headline and a detailed report on the transportation process. From now on, regardless of whether there is a transportation task or not, the train from the kiln to the smelting field will carry a passenger car, and it will run back and forth in the morning and evening.

Trains are the most comfortable and convenient way to travel between the smelting yard and the kiln. The people of Yaogang unconsciously entered the era of trains. Almost every outsider who arrives at the kiln will take a train to go around the smelting field, and if they don't take the train once, they will feel that they have come to the kiln for nothing. Fortunately, the round-trip train ticket to the smelting field only costs ten copper plates, which is not expensive. If you are the workers and their families of the kiln, you still don't need money to take the train.

Soon after the train was opened, there was not enough passenger cars, and it was often impossible to squeeze in, let alone seats. I had to hang another passenger car.

The sound of the whistle and the roaring train with black smoke are another scenery of the kiln.

Li Mao's return is one of the best in Yaogang this summer.

Li Mao not only came back with Mu Yi, but also brought back Lu Qi who went to Nanyang.

Li Mao and the others sold so much silver that they stopped in Changsha for a few more days and filled almost all the barges with manganese ore and tin and tin ore. However, many silk and tea merchants contacted by Mao Huier came to the dock and asked Li Mao to take some more of their goods. I had no choice but to take care of a lot of ships, loaded with cargo and dragged behind tugboats and steam shallow ships.

Mu Yi said to Li Mao: "This time it's a big trouble. Wuchang doesn't know how much cotton and hemp has been prepared for us, how can we ship it back? ”

"It's okay, the boat will naturally go straight to the bridge. It really didn't work, so we had to hire another ship in Wuchang. Fortunately, we went all the way down the river. If I don't think it works, the two of us will go separately when we arrive in Jiujiang. I'll take people to Jingdezhen to pick up those barges, and you take people directly to Zhenjiang to go back. We will meet again in Huai'an. Li Mao said.

"Looks like that's the end of it." Mu Yi said.

Mu Yi took away a large amount of silk tea in Changsha, so that the people of Changsha were full of gratitude to the kiln people. Because of the war, their products can't be sold, and they really starve for good things. This time, Li Mao and the others made a big deal of money, and bought the goods in their hands several boats and ships, which helped them a lot. Mao Huier's prestige in Changsha is already very high.

Sure enough, as Mu Yi said. The Wuchang wharf was full of cotton and hemp prepared for Li Mao and them.

Song Tao, who was waiting at the Wuchang wharf, was also worried when he saw Li Mao's fleet, "Shopkeeper Li." I see that your barges are fully loaded, what do you do with the cotton and hemp we have prepared for you? ”

Li Mao smiled and said, "Don't worry about the shopkeeper Song, I will transport all your good things." But you're going to rent a boat for me. ”

"Thanks to the fact that you gave our host a fishing attention last time. Boats can still be hired on the docks now, if there were not many boats on the Yangtze River before. After Song Tao finished speaking, he asked, "But there are so many boats, can you all tow them?" ”

"Rest assured, we have two shallow steam ships, a tugboat, and two warships. We can all tug boats to go, not to mention that we go down the river when we go back, no problem. Li Mao replied.

In this way, Li Mao and the others stayed here in Wuchang for a few more days, and hired a ship here to load the ship.

When they left Wuchang and arrived at Jiujiang, Mu Yi took two shallow boats and a warship to tow the cargo ship, bid farewell to Li Mao and them, and went directly down the river to Zhenjiang, leaving the warship. From Zhenjiang into the canal, passing through Yangzhou, directly to Huai'an. Because many shippers were reluctant to go further north, Mu Yi had no choice but to unload the goods in Huai'an.

Li Mao took the tugboat across Poyang Lake to Jingdezhen, where he saw that the porcelain, paper and heavy stones he had ordered were loaded on a barge. Li Mao rushed to the porcelain kiln to thank the kiln owner. Because of the situation, Li Mao paid all the silver, so that people could let you load porcelain. After Li Mao finished settling the money, the kiln owner said: "We don't dare to break the rules for other buyers, but we don't have any rules for doing business with you kiln people." There is nothing you don't know about your reputation in Jingdezhen, and you never care about doing business. If you say you brought a little less silver this time, we'll wait for you to bring it next time. ”

Li Mao thanked the kiln owner again. It's such a reputation, it saves a lot of time, and that's also the money saved.

Li Mao left Jingdezhen and stopped in Yangzhou. Just in time for Lu Qi to rush here.

Lu Qi said that after they received rubber from Nanyang, they bought a lot of pearls and spices, and hurriedly hired a ship to transport them to Guangzhou. In Guangzhou, they planted the rubber saplings they had brought back in the mountain fields they had bought, and asked them to watch them carefully. happened to meet Li Mao sent people to Guangzhou to buy grain, so he followed the ship to buy grain and transported the rubber to Huai'an Wharf. When the ship arrived in Huai'an, he hurriedly rushed to Yangzhou, and happened to miss it with Mu Yi.

Li Mao said: "When I arrange the affairs of Yangzhou, you can go back to Yaogang with me." ”

When Li Mao and Lu Qi came to Huai'an, it happened that the tugboat from Yaogang came with a barge to transport grain. Li Mao said: "Let's transport the grain slowly, and first transport the things we brought back for urgent use." With tugboats and barges, the return transport is much faster. ”

Even so, Li Mao was anxious to hurry back day and night. When I didn't rush back, I wasn't in such a hurry, I was really close to home. Especially what the kiln will be like after a big war, Li Mao is very worried.

Lu Qi also walked for another year, and he was also homesick. Two homesick people rushed back together.

However, when they arrived at Lingshui Wharf this time, they refused Fan Chengkun's enthusiastic retention, and insisted on leaving, they didn't expect that they would not take a car to go back to Yaogang this time, but by boat.

Li Mao said: "If I don't come back, I may not be able to find the door when I enter the house." When he spoke, Li Mao's heart was mixed.
