Open an aircraft carrier to fight against Japan

Zhang Zesheng didn't care about Master Li's suspicion, and said to Master Li: "Tell me about the general process of your craft first. If you can't make the glaze like the original one, where is it stuck?"

Master Li said: "The most important thing for us is that we cannot replicate the fineness of the original glass." Master Li said, taking a glass cup from the side, and said: "This is our recently fired glass cup." Master Li put it on the table, then took out an original colored glass and put it beside it.

Lin Yuan looked at the two glass cups and instantly understood: the newly fired glass cups are far worse than the original cups in terms of color and transparency, so that a layman like himself can see the two glass cups at a glance. pros and cons.

Master Li pointed to the two glass cups and said to Zhang Zesheng: "I believe you don't need to tell me which glass cup is better. The most important thing about whether the original glass cup can be fired is the composition of various ingredients." Proportions, when firing colored glaze, there are dozens of ingredients, and there are even more changes in the proportions. In this way, there are thousands of proportions that need to be tried, so we still can’t try them out.”

Zhang Zesheng nodded and asked, "Is there any broken glass?"

Master Li asked, "What do you want the broken glass for?"

Zhang Zesheng looked at Lin Yuan, and Lin Yuan winked at him, meaning: don't reveal our secret, so Zhang Zesheng said with a smile: "You can find it for me, and I will explain it to you later."

Master Li went to a corner and opened a big box. Inside was the glazed peacock that Zhang Ziyu smashed that day. Master Li held the box in front of Zhang Zesheng and said, "Look, here are the things."

Zhang Zesheng rummaged through the broken glazed pieces for a while, picked out a few pieces, and asked, "Are these the original colored glazes? Where are your failed samples? I want your failed samples."

Master Li sighed helplessly when he heard this, and said, "Follow me."

After Master Li finished speaking, he walked out of this cave, then walked into another cave, and lit the oil lamp. The scene inside surprised both Lin Yuan and Zhang Zesheng, because the inside was so huge that it was just Three times the size of that cave!

I saw a lot of wooden shelves in the cave, and there were boxes on the shelves. Master Li picked up the nearest box and said, "The things in it are all our failures. Every time we fail, we will lose everything." Put the glass piece in this box."

As he said that, Master Li took out another piece of paper from the box and said, "This is the process of firing this glazed piece. It records the ratio of each ingredient and the heat."

Zhang Zesheng took the piece of paper, looked at it for a long time, and asked: "When you are recording the heat, what do the light cyan, sky cyan and dark cyan colors mean?"

"We use them to indicate the size of the fire," said Master Li.

Lin Yuan knew that the temperature of the fire was very important when firing colored glaze. If the temperature differed by more than ten degrees, things would not be burnt with charm. Ancient people had no concept of temperature, so they used the color of fire to record the temperature.

Zhang Zesheng nodded and asked: "Different people must have different perceptions of the same color. You may see it as dark cyan, but I may see it as light cyan. I don't know who recorded the heat when you were recording. ?”

When Master Li heard Zhang Zesheng's questioning, he looked serious and said, "It seems that you are really an expert. I already knew about this matter, so we have always asked one person to record the heat, and that person is here."

Zhang Zesheng said: "Well, let your people suspend work temporarily, and you burn all kinds of fires for me, I want to take a look."

Master Li didn't understand what Zhang Zesheng was going to do, but Lin Yuan and Zhang Ziyu had told him to listen to Zhang Zesheng in everything, so he didn't say much, and went out to prepare. As soon as Master Li left, Lin Yuan asked, "What is this?" What to do?"

Zhang Zesheng said with a smile: "I want to convert these heats into temperatures we are familiar with. I bring an infrared thermometer. After I record these temperatures, I can start the process recovery." Master Li walked in at this time , said: "The stove is ready, do you want to go over now?"

Zhang Zesheng nodded. Just as Lin Yuan was about to go out with him, Zhang Zesheng reached out to stop him, and said, "Don't come here, stay here and do something for me."

As Zhang Zesheng said, he took out a camera-like thing from his bag, and said to Lin Yuan, "This is a visible light spectrum analyzer." Then he took out a flashlight-like thing from his bag, and said, "This is a White light source."

Zhang Zesheng held a white light source and said: "Use this to irradiate those glass sheets, and then use a spectrum analyzer to take pictures of the glass sheets, take a reflection of the light on the front side, and then take a transmission light on the back side, the spectrum analyzer can automatically record the reflection. composed of light waves of light and transmitted light."

After Zhang Zesheng finished speaking, he took out the original glass piece from his arms, and said: "After taking pictures of the fragments in this room, record the original ones." Lin Yuan asked: "What's the point of taking pictures of these pieces?" Is it useful?"

"With this data, we can build models and figure out how much we should adjust the ratios and temperatures of various ingredients," Zhang said.

Lin Yuan nodded. After a busy day, the two of them split up and recorded all kinds of data. When they returned to their residence, Zhang Zesheng took out a laptop and entered all kinds of data into it. Thousands of sets of data had been entered for nearly It took one night to complete the input.

Lin Yuan asked: "Then what? Don't you want to exhaustively enumerate all possible calculations?"

Zhang Zesheng said: "How is that possible! There are so many situations that can't be calculated until the end of the world! Our software is like this. We input the spectral characteristics of the original glass, and the software will use this data as the target, and then according to The existing data, automatic calculation and simulation under which composition and temperature may obtain the original characteristics."

Lin Yuan suddenly thought of a word and asked, "Is this just an artificial neural network?"

Zhang Zesheng said with a smile: "Yes, this is an application of artificial neural network. This calculation method can automatically learn based on the existing data, and then generate the results we want."

At this moment, the sound of the computer's fan suddenly became louder. Zhang Zesheng said, "It seems that the amount of calculation is a bit heavy, and the computer can't take it anymore." Zhang Zesheng entered a command casually, and a window popped up. Zhang Zesheng looked at the window and smiled. : "Let's sleep for a while, the computer will calculate the result in four hours."

Lin Yuan and Zhang Zesheng went to sleep with their clothes on. When they woke up, it was already noon. Zhang Zesheng looked at the window and said with a smile: "The calculation results are out, and we have obtained five groups of the most suitable results."

Lin Yuan said: "Great, let's send the results to them right away." Master Li was already waiting in the firing workshop. The materials were put into the furnace, and the anxious waiting began.
