Chapter 1134 Telegraph

So Su You locked up several people again, along with their good friends, Liu Zhengfu, a student of Tai, Huang Shang, a scholar from Yanping, Fujian, and even Wang Zhongyu, the son of Wang Qi, and Xing Ju, Xing Shu's son, were also locked up, and they were all locked up, and they were all locked up, and they were ...... Brush questions.

Liu Zhengfu is a student whom Su You admires very much, and his subordinates are literary and upright.

As a humble student, he dared to write anonymous articles to scold the court for treating Dasu unfairly; When the flood came, he took the initiative to help Kaifeng Mansion to fight the flood, and his ability was outstanding and he was elected as a leader by the students.

Su You also deliberately reviewed Liu Zhengfu's performance appraisal in Taixue, which can be called a scholar, and he is not resistant to all kinds of learning, and he is sensitive and motivated.

Su You felt that if he compared it with the older generation he had seen, Liu Zhengfu was almost a figure around Feng Jing and Zhao Bian.

Huang Shang is a little strange, this baby is a relative of the famous literati Huang Lu on Fujian Road, and Huang Lu's father-in-law is Shen Kuo; Huang Lu's son-in-law is Lu Huiqing.

From this line, Lu Huiqing had to call Shen Kuo grandpa!!

The most funny thing is that although Huang Lu is an anti-new law person, he was listed as Wang Anshi's party because of this, and now he is serving as the imperial historian in the court.

So Su You received two letters and a post, respectively from Nanhai, Luokou and Yushitai, asking him to take care of this son, saying that he was a Wenkui seedling on Fujian Road.

The ecology of the Great Song Dynasty is like this, and the relationship between the scholars and doctors is very complicated.

For example, Feng Jing's daughter married Cai Qu's son.

As for Han Jiayan and their family, it is almost related to most of the famous families in the Great Song Dynasty.

Sometimes Su You thinks that the so-called "follow your father at home, and follow your husband when you marry" is not unreasonable.

If there is no such rule, many juniors in the doctor's family will have their heads broken in bed.

No matter what the elders are doing in the court, the relationship between the juniors is now very harmonious, and everyone has their own opinions.

Xing Shu and Wang Qi also expressed their peace of mind that their son was locked up by Su You.

Is there a sheep uncle in the world?

Similarly, they all believed that Su You's locking up his son in Kezhentang would only be good for them.

Neither of them completely tore their faces with Su You, although the dark arrows flying in the court were coming and going, they both dared to put their sons with Su You with confidence.

This is also the greatest affirmation of the Su family's character.

What are you kidding, Su Wen is familiar with mutton, and there are countless Qiwen secret books in Kezhentang, and it is said that there is also a mysterious baby of Su Mingrun who is young and takes flowers.

The Great Song Dynasty Chongjinshi, Wang Qi and Xing Shu were also well-intentioned for the sake of their son's future, and they didn't care about their face.

Su You didn't care about this aspect, when he heard Su Mai come over and tell the little master that he had a few friends who were outstanding in literature, and everyone was ready to meet in Kezhen Hall for half a year to retreat and fight in the field, Su You just asked who they were, and then said "oh", telling his nephew and disciples to be humble, ask more people for advice, and take care of each other.

As for food, housing, pen, ink, paper, inkstone, etc., the little master has packed it for you.

……

Bianjing, partial hall.

Zhao Ji was with Su You and Feng Jing, watching a new army team brought by Su You tinkering with a magical gadget there, while pulling the gossip above.

According to Su You, this thing is called a telegraph.

Telegraphs need power, and the power source is a battery.

The lead-acid battery was actually born when Su You and Xiao Tianshi met for the first time, and the temporary and simple equipment used to electrolyze water can be regarded as the initial model of the lead-acid battery.

Later, Shifu used it for electroplating and etching to add a delicate texture or coating to the metal surface.

This is just needed, but also the great secret of the four links, many scribes on the handle of the knife, the impression of the treasure banknote, those thin as hair, in the eyes of outsiders is simply incredible, in fact, it is sealed with wax to seal the metal parts, and then use the tip of the needle to scratch off the wax layer, add the DC electrolytic cell etching out.

In this process, in order to be convenient to use and long-lasting and stable performance, the battery has been continuously improved, in addition to ordinary lead-acid batteries and dry batteries, now Sitong and Tianshifu have begun to study how to charge lead-acid batteries.

At present, this transmitter uses a series of dry batteries as a power source.

A dry cell battery is a chemical battery that uses a paste electrolyte to generate direct current and can only be used once.

The electrolyte is an immobile paste with a positive carbon rod in the middle, a mixture of graphite and manganese dioxide on the outside, and a web of fibers coated with a thick electrolyte paste consisting of ammonium chloride solution and starch and a small amount of mercury preservative.

The outermost layer is a shell made of metal zinc skin, which is the negative electrode.

Battery discharge is the process of electrolytic reaction between ammonium chloride and zinc, and the released charge is conducted by graphite to the positive carbon rod.

The electrolysis of zinc releases hydrogen, which reduces the power of the battery, so the Celestial Master added a coating of manganese dioxide mixed with graphite to the outside of the cathode to absorb the hydrogen.

This set of things has developed to this day, Sitong and the Heavenly Master's Mansion have been very clear and thorough, and the application has been quite mature.

After Su You proposed the topic of speeding up communication, he clicked on the golden finger of the magnetic cutting line for Xiao Tianshi by the way.

This thing is the key principle for charging motors and lead-acid batteries, but there is still a long way to go, without diodes, rectifiers cannot be manufactured, and direct current can only be output through brushes and steering gears.

However, Su You doesn't need these now, these are the topics that the Heavenly Master's Mansion and the Royal Institute of Technology will study in the future, and he only needs two pointers that can be driven by a small coil driven by direct current.

One pointer moves to indicate 0, and two pointers move together to represent 1.

With this, the light signal used by the sailor can be converted into a signal indicated by the pointer, and the coded book of the sailor can be used.

In order to achieve accuracy, Zhang Tianshi sacrificed some efficiency, and before the sounder was made, it was not very reliable to distinguish between long and short signals, so he used such a signal system that had never been seen in history.

This requires two circuits to be responsible for receiving, two circuits to be responsible for sending, and eight rubber-wrapped copper wires are needed as cables.

Su You also went to Chen Zhaoming to invent a set of algorithms, adding a check bit to each signal, through the logic algorithm, the correctness of the signal can be checked at the receiving end, to avoid information errors caused by the loss of signal parts.

This polytechnic group is part of the Royal Military College, and the project is codenamed "Di Ting".

The clock in the side hall pointed to the beginning of the day, and with the melodious sound of the bell, the hands of the telegraph began to shake.

The group leader turned his head: "Your Majesty, Prime Minister, Guogong, I have received a request from the Heavenly Master's Mansion. ”

This is a set of codes, and the telex message has some basic codes that are used as a quick communication.

Zero-zero-one, which indicates a request for communication.

Su You nodded: "Reply, ready to receive." ”

There are two buttons on the transmitter, one press will only connect to a single channel, and the other press will connect to a double channel.

After a while, the two hands that received the signal began to shake again, and the two recorders were nervously recording the signal on the side.

It was a table, and after recording and checking it correctly, the team leader handed it to the translator and recorded the text in the last space of each line of the table by flipping through the codec.

In fact, this code is also regular, the translator is the ace trumpeter drawn from the South China Sea Fleet, and the code is memorized in his mind, but in order to be foolproof in front of His Majesty, the translator still flipped through the code and checked it once.

Soon, the group leader handed over the translation to Su You, who smiled and handed him over to Zhao You.

When Zhao Ji saw it, he couldn't help but be happy and handed it to Feng Jing.

Feng Jing took it and looked at it, and there were six words written on the decoding table, "The sky is raining, and the ghost is crying at night." ”

This is an allusion, "Huainanzi Benjing Training": "The former Cangjie wrote books, and the sky rained, and the ghosts cried at night." ”

Zhang Tianshi This is the invention of the telegraph, which is more important than the creation of characters in Cangjie.

Su You bowed down and said, "Your Majesty, how to reply, please give me instructions." ”

Zhao Ji smiled: "This stumps me, both of you are scholars, so you should come up with it." ”

Feng Jing's heart was agitated: "Tao Te Ching" cloud: If you don't go out of the house, you know the world; Don't peep, see the way of heaven. ”

"The Heavenly Master made this artifact, which is secretly in line with the forty-seven chapters of the Tao Te Ching, and there must be a providence in the dark. It's better to reply to him, 'I don't know, I don't see it.' 'How?' ”

Su You said with a smile: "Prime Minister is very good, but there is no more appropriate." ”

ps: Push the book, "The First Ruthless Man in Nanming", the author is also lv5. Through the Yongli Emperor Zhu Youlang, the sun and the moon shine on the clear land, and the whole world is descended. Clear, I want to clear!
