Open an aircraft carrier to fight against Japan

Lin Yuan smiled disdainfully: "It's useless even if I tell you, because these things are not something you can produce at all. To give you the simplest example, ethylene oxide, can you produce it?"

The curator is a student of history, and has spent most of his life dealing with books. He knows nothing about chemistry, so he didn't understand the word "ethylene oxide" at all.People are like this. They always have resistance and contempt for things they don't understand, so the curator said: "What are you talking about? Why can't I understand a word!"

Lin Yuan smiled and said, "There are so many things you don't understand, can you deny its correctness just because you don't understand?"

The curator said impatiently: "Stop talking nonsense here, get out of here!"

Lin Yuan then pointed to the storage cabinet next to him and said, "It's fine if you don't believe it, but the precious cultural relics in your museum have already been damaged. If you want to watch them continue to be damaged, then please do so."

After Lin Yuan finished speaking, he turned around and left. The curator said from behind: "Do you have a way to prevent them from being damaged?"

Lin Yuan smiled and said: "Of course I have a solution! But you are too backward here, and I have no solution. If they are transported to China, I will definitely be able to save them!"

Lin Yuan went on to say: "These collections are the treasures of the world, and you have the heart to let them stay here to mold and deteriorate? Our descendants will spit on our graves!"

The curator thought for a while and said, "I can't trust you for no reason. So, what are you going to do to prove that you are really capable of protecting these cultural relics? If you can do it, I will trust you."

Lin Yuan said coldly: "I am also a person who does not want to see the destruction of precious cultural relics. My purpose of coming here is also very simple, that is to send these precious cultural relics to China and protect them well in our country. If I can prove that I have the ability to protect them, you will send all these precious paper and silk cultural relics to China!"

Lin Yuan thought very clearly that most of the Chinese cultural relics in the Paris Municipal Library are paper products and silk fabrics. This will not only bring back the precious Chinese cultural relics, but also the French looted from ancient Egypt, ancient Babylon and other countries. Precious cultural relics can also be returned.

The curator said: "We just got a batch of precious paper from China, which is said to be the imperial edict of the Nanzhao king. If you can protect them well with the technology you mentioned, I will agree to your request."

Lin Yuan knew that Nanzhao was a minority government established in Yunnan in the Tang Dynasty. It was later destroyed by Duan Siping and Dali Kingdom was established. Lin Yuan also knew that the area of ​​Yunnan has always been the sphere of influence of the French. China and France once fought in Yunnan. It was a battle, but Lin Yuan couldn't figure out where they got these precious cultural relics.

Lin Yuan asked, "Where did you get these things?"

The curator replied: "We bought it from the local people. It is said that the local people dug up the tomb of a Nanzhao minister and got a lot of good things from the tomb. Among them, gold, silver and jade were bought at high prices. , the remaining silk fabrics and books are not wanted, so we can get back a large amount at the price of less than a catty of eggs."

Lin Yuan sighed silently in his heart, and then said: "You don't understand technology at all, can you evaluate my ability to preserve cultural relics?"

The curator said: "I will find my colleagues, many of them are experts in cultural relics protection."

Lin Yuan said: "Okay, you hurry up and find someone, and I will show you my skills tomorrow."

The curator agreed, and Elena sent Lin Yuan to the door, and asked cautiously: "Do you have that kind of ability? I know that Dad has some friends who are very experienced experts. Many of them are already in the I have been studying the protection of cultural relics all my life.”

Lin Yuan smiled and said: "Don't worry, they are definitely not my opponents." Lin Yuan bid farewell to Elena, went to find the Curies, and brought the chemicals needed for tomorrow from where they worked, and waited until they returned. The post office asked someone to send a letter to President Fall, urging him to persuade the parliament as soon as possible. In the letter, Lin Yuan threatened and intimidated, and the wording was extremely strong. The person who sent the letter came back and reported that President Fall was already working hard. Many people in the parliament have already agreed.

On the second day, Lin Yuan brought his assistants to the Paris Municipal Library. As soon as he arrived at the door, he saw Elena standing aside with a sad face. Lin Yuan quietly stepped forward and asked, "Do you still need me to help you?" gone?"

Elena recalled what happened yesterday, she couldn't help but blushed, and hurriedly said: "I was almost discovered by my mother yesterday, and I will never dare to do that again. By the way, are you ready?"

Lin Yuan smiled and said, "Of course!" Lin Yuan couldn't help but look back at the assistant carrying a lot of chemicals, and thought, "It would be great if I could use a computer to show slides."

Elena led Lin Yuan into a lecture hall. An optical projector was placed at the front of the lecture hall. This kind of projector can use optical elements to magnify the content on the paper and then image it on the screen in front of it. The projectors used by Lin Yuan are all connected directly with computers and other equipment using electronic technology. Lin Yuan had seen this kind of optical projector when he was in elementary school.

Lin Yuan looked at this old projector and thought: "I still have some pictures that I want to show them during the speech. This time is just right, I can use this projector." Lin Yuan looked at the audience , I saw that everyone in the audience looked at him with ill intentions, as if they were waiting to see his jokes, Lin Yuan thought to himself: "Well, since this is the case, I will tell you some things that you all listen to. I don't understand."

Lin Yuan took out a map of the electromagnetic spectrum from his bag. This map shows the various bands of electromagnetic waves. Lin Yuan wanted to use this map to illustrate the harm of ultraviolet rays to paper cultural relics. Lin Yuan thought Thinking: "The map of the electromagnetic spectrum was only drawn in the [-]th century. You must have never seen it before. Just wait to be shocked by me."

Lin Yuan turned on the projector and put the electromagnetic spectrum on it. He didn't expect to hear laughter instead of exclamation. Lin Yuan was puzzled and thought: "What's so funny about you?" Turning his head to look Only then did I realize that the picture turned out to be upside down on the screen!It turned out that the optical projector formed an upside-down image when projecting, so everyone burst into laughter.

Lin Yuan hurriedly turned the picture around, stretched out his hand to signal everyone to be quiet, and then said: "Today I will tell you about the damage of light to paper cultural relics."

Everyone didn't think that light can cause damage to cultural relics, so they all calmed down and listened. Lin Yuan continued: "Everyone knows that paper cultural relics are easily damaged, because the main component of paper cultural relics is cellulose. Things are very fragile, and they are easily oxidized and destroyed under the irradiation of ultraviolet rays, so when storing, the light source in the storage room should be strictly controlled, and the light source should be a cold light source that does not emit ultraviolet rays.”

Lin Yuan pointed to the electromagnetic spectrum on the screen, and said, "Everyone, please look, this is the position of the ultraviolet rays." As he spoke, Lin Yuan took out another pen-like object and pressed it against the screen, and everyone couldn't help but scream. There was an exclamation.
