- Zhu Houzhao looked at Liu Jin's expression and smiled proudly.
To be honest, anyone who sees this thing for the first time will be shocked by it. It does not require candles, oil, or firewood, and it can light up the night like a candle.
This is a miracle, an incredible and great invention.
At least that¡¯s what Zhu Houzhao thinks.
"What is this?"
Although Liu Jin already knew that this was an early electric light, he still had to pretend to be surprised and asked.
"Haha, as for this thing, I named it an electric light, which means to use electricity as a lamp for lighting."
Zhu Houzhao said with a smile: "Let me tell you, we discovered this accidentally and then finally studied it through a lot of experiments."
"In the process of studying electromagnetism, we found that when current passes through some objects with relatively large resistance, the objects will heat up quickly, so we wondered if we could study this phenomenon separately."
"Unintentionally, we also discovered that when the current is large enough, it will not only generate heat, but also gradually light up, and then become as bright as a candle, or even brighter than a candle. "
"So I studied this thing specifically, and slowly discovered a lot of interesting things. After thousands of experiments, we slowly developed the electric lamp in front of us."
"It is made of silk yarn obtained by carbonizing cotton silk. When it is turned into a spiral shape, and an electric current is connected, it will emit bright light. The intensity of this light is much stronger than that of a candle."
¡°And it can last for dozens of hours!¡±
Zhu Houzhao couldn't hide any secrets or things at all. He didn't need Liu Jin to ask anything, he just told everything by himself.
¡°Cotton silk carbonization?¡±
When Liu Jin heard this, he immediately frowned. Shouldn't this filament be made of tungsten filament?
Can this cotton filament be used to make filament?
Of course Liu Jin didn't know that. In fact, in the history of the development of electric lamps, in the early days, when scientists conducted research, they used cotton silk, bamboo silk and the like to be carbonized first, and then used as filaments. It was not until later, at the beginning of the 20th century, that the Austrians invented tungsten wire.
Compared with cotton and bamboo filaments, tungsten filaments are brighter and have a longer lifespan. This is how electric lights have truly begun to enter thousands of households.
"Yes, uncarbonized cotton will be burned directly. Only after carbonization can the cotton be used as a filament. Only after being powered on can a bright light be emitted."
Zhu Houzhao nodded and said: "In fact, not only cotton silk, but also many plant fibers can be used as filaments. We have experimented with hundreds of plant fibers and found that cotton silk is relatively the best filament. "
¡°Why not use wire?¡±
Liu Jin thought for a while and said.
"Metal wire is not suitable, because the melting point of metal wire is generally low, and it often melts immediately when electricity is applied. The wire after carbonization with these plant fibers is different and will not melt all at once."
Zhu Houzhao said quickly: "I have tried using copper, iron, aluminum, lead, gold and silver, etc., but they all don't work. They will melt soon and have no practical significance. At present, only this carbonized cotton silk is relatively It can be used longer and can illuminate for dozens of hours." At this time zuqiuxiaoshuo.com Zhang Si
"That's it~"
"Then this should be related to the melting point. If it is made of metal wire with a high melting point, I feel it may be much better than cotton silk."
Liu Jin touched his chin, thought for a while and said. 强牺 zuqiuxiaoshuo.com 读牺
"You are so smart, you figured out the key points right away."
"This is indeed related to the melting point. The melting point directly determines the life of the lamp."
"Metals generally have very good conductivity. If metal is used to make wires, the brightness will indeed be stronger than the cotton silk in front of you. However, there is still no metal wire that can withstand high temperatures."
"According to the data we calculated, after power is turned on, the temperature of the electric filament is more than 1,000 degrees. This temperature can melt almost all metal filaments."
"Of course, there are not many types of metal wires currently being tested. I will let people continue to experiment later."There are various kinds of metal wires, and each metal has different characteristics. Maybe you can also find some high-temperature resistant metal wires. "
When Zhu Houzhao heard this, he immediately gave Liu Jin a thumbs up.
Liu Jin is really evil. He immediately thought of the key point. As for the melting point, Zhu Houzhao and his team finally decided on it after many discussions.
Liu Jin discovered the crux of the problem at a glance. Knowing that the key point of this filament is related to the melting point is really admirable.
"In my opinion, the service life is not only determined by the material of the filament, but also by the reaction produced by the filament."
Liu Jin thought for a while and then said.
"How to say?"
Zhu Houzhao asked quickly after hearing this.
"When I went to Imperial College last time, I heard a professor from Imperial College talk about how the air is very complex. There is oxygen that can be used for breathing by humans and animals, and there are also some useless gases."
"According to their research, they believe that oxygen is a very active gas and can easily react chemically with some things. For example, oxygen is needed when burning. Without oxygen, candles cannot burn."
"Your filament is directly exposed to the air. After it is powered on, it will generate high temperature, which can easily react with the oxygen in the air, causing its lifespan to be drastically reduced."
Liu Jin pointed out to Zhu Houzhao some key points in making lighting lamps for later generations. Zhi Da Zhi Xiao
Electric lamps, electric lamps, don¡¯t say that they are filled with inert gas or something, at least you need to get a vacuum bulb, so that it can have a longer life.

?It is strange that the service life can be long if it is directly exposed to the air.
"Yes~"
"I actually forgot about this."
¡°Last time, I also heard someone talk about oxygen, saying that oxygen can assist combustion.¡±
After Zhu Houzhao heard this, he suddenly slapped his thigh.
"Let me tell you, the reason why the service life of the filaments I studied is very short, it turns out to be because of the oxygen in the air."
"Then how to solve this problem?"
Zhu Houzhao suddenly became thoughtful. He looked at the glowing filament and began to think hard.
This time .com Zhang Si. Liu Jin on the side looked at Zhu Houzhao who was thinking hard, and then looked at the researchers around him. They were also thinking hard now. Only Liu Jin, the little eunuch, did not think about these troublesome things.
He is already in his sixties Yes, it¡¯s been a lifetime.
??????????????????????????????????????????????????????Out out of history, as Zhu Houzhao became the emperor, he also became the Eunuch Liu that everyone feared. Of course, he died quickly as he was brilliant.
??Historically, he was killed in the fifth year of Zhengde, but now it is the twenty-eighth year of Hongzhi, which counts as the tenth year of Zhengde in history.
He is still alive and well, and is still the little eunuch beside Zhu Houzhao. If nothing happens, he will be seventy years old in a few years, and he will be able to enjoy his old age and retire gloriously.
Although he has never tasted the taste of power, he can still live to old age peacefully. I don¡¯t know whether it is a good thing or a bad thing for him.
Sometimes it¡¯s true that blessings and misfortunes depend on each other, and there are gains and losses.
Looking at Liu Jin, Liu Jin thought of himself. He didn't know whether it was a blessing or a curse for his high position. Since ancient times, there were not many ministers who could die well, especially reformers like Liu Jin who sat at the top. Auxiliary above this position.
Shaking his head slightly, Liu Jin put these disturbing things behind him.
At the moment, it seems that the electrical age is coming soon.
With the electric lights coming out, it is estimated that other related electrical appliances will also spring up like mushrooms after a rain.
Control the big one and control the owl. This speed can be said to be very fast.
¡°The road that historically took hundreds of years to complete, the Ming Dynasty has now completed in about 20 years.
With the advent of electric lights and the arrival of the electrical age, the technological revolution and industrial revolution will develop and change in depth, bringing huge changes to the entire society.
In the future, the Ming Dynasty may move towards greater prosperity, but it may also cause large-scale unrest. After all, the power of capitalism will become stronger and stronger, and the systems and ideas of feudal society will severely restrict capital. With the development of China, the contradiction between the two will become increasingly acute
