His father, Lu, used to work in xiushui county Cultural Center. In 2003, he took Lu Yulong to Shenzhen. At that time, Yulong was only 8 years old and studied in a primary school in Baoan, Shenzhen. He has a talent for loving science since he was a child, and he is very curious. When he was in the second grade of primary school, he often went to junior high school classes for chemistry classes.
When he was 9 years old, he found a bottle of perchloric acid in the hospital, so he began to do experiments. He loved learning and doing research. But once, he accidentally let the liquid flow out and burned his thigh, and there are still scars. But this kind of burning did not make him lose confidence, but deeply aroused his interest. Yulong built a chemical testing room by himself. 13 years old, doing high-energy chemical reactions at home, taking the prepared materials to the gap outside the house and lighting them. At that time, I just wanted to try to test its reflection ability by constantly adjusting the proportion of chemical dose. I didn't expect it to explode like this. His right leg, left hand and face were seriously injured by the explosion. Yulong fainted and was hospitalized for more than a year. Until now, there are still sequelae, the eardrum is damaged and the whole body is covered with scars. Lu Yulong is still undergoing repair, excision and suture in the hospital. However, he thinks that the hospitalization time is too long and the time for examination is wasted. Lu Yulong secretly left the hospital and continued his experiment until the experiment was successful.
Stick to your dreams.
/kloc-Yu Long, 0/6 years old, assembled his award-winning work-transistor plasma arc dual-channel loudspeaker. This kind of loudspeaker has incomparable advantages: the traditional loudspeaker pushes air through the diaphragm to form sound waves, and the inertia of vibration will cause the actual sound to lag behind the audio signal. Theoretically, such a loudspeaker can directly promote air pronunciation through plasma and perfectly reproduce audio signals. Two pink-purple beams are respectively connected with the upper and lower ends of the two groups of electrodes. With the dazzling light beam flashing, wonderful music is emitted from the plasma of these two beams, which is wonderful. His works won the first prize of Guangdong Youth Science and Technology Innovation Competition, became the only physics project submitted to the national competition in Guangdong Province, and won the second prize of the physics group of "National Youth Science and Technology Innovation Competition". Experts believe that his works are mainly novel in design and well-made. Yulong has applied for a national patent for this technology. He believes that this technology is highly likely to be mass-produced and will enter the homes of ordinary people like plasma TVs.
What surprised Yulong was not only the design of this plasma sound, but also his fantastic "artificial lightning". It is fatal for ordinary people to touch the 220-volt circuit, but Yulong can reach out and touch the high-voltage arc with a peak value exceeding 500 kV in the experiment. This is not because he has special functions, but because Yu Long has mastered a set of his own methods. Now, I am playing "Tesla coil" (technical term "Tesla coil"). The principle is to boost the common voltage with a transformer, and then discharge it from the discharge terminal through a bipolar coil. ) In terms of equipment, Yulong is already the "top" level in China. "In China, his' playing' is the strongest and the radian is the biggest." Many people asked curiously how Yu Long fell in love with this. In an interview with reporters, Yu Long opened the topic: "It was an accident, but it was also reasonable. The award-winning invention was completed from February to April 20, 2009. Because I am a high school student, I have to study and the experiment has been interrupted several times. " He said while doing it: "In a double resonance solid-state Tesla coil experiment, I was surprised to find that by changing the frequency of the modulation signal, the sound emitted by the arc can also be changed, so I became interested in the speaker. Later, I improved my invention by consulting relevant foreign materials and constantly experimenting. This invention is currently applying for a national patent. " According to relatives and friends around him, he stopped playing after being fascinated by these things. He just stayed indoors to do experiments all day and often forgot to eat. Some professors from Tsinghua and Peking University often come to Yulong to discuss related physics topics. His experimental notebooks are piled up more than a foot high. What's more gratifying is that after winning the prize, Yulong got the qualification of walking, that is to say, without the college entrance examination, he can be selected by national key universities such as Peking University and Tsinghua, which is really exciting.
Continue to walk with lightning in the future
Finally, the reporter asked Yu Long what to do next. Yu Long said with a smile, "I'm going to find a place of 200 square meters or 300 square meters to expand my laboratory and continue to do experiments. I tried to take Tesla coil to Hong Kong for exhibition, and I earned 50,000 yuan to buy all the experimental materials, which also reduced the financial burden of my parents. I am registering a company called Tunguska Technology Co., Ltd. "I asked," What does Tunguska mean? " He smiled and said, "Tunguska originated from a big bang. I'm studying electric cannons. We know that traditional guns and cannons use chemical energy such as gunpowder, and I study electrical energy to make guns and cannons have the same use. You see, this aluminum plate with a thickness of 1.5 cm was pierced by electric shelling 30 cm away. " As a leader of Shenzhen Association for Science and Technology said, this is the pride of Shenzhen and the leader of hundreds of thousands of high school students in Guangdong. I said, it is the pride of our water conservancy people and the leader of hundreds of thousands of high school students in Jiangxi. I must tell my hometown people that they are proud of having such a baby to repair water and let them share the joy. PS: Tunguska is in Siberia, Russia. There was a big explosion at the beginning of last century. At that time, it was estimated that the explosive power was equivalent to10 ~150,000 tons of TNT, and 60 million trees over 2 150 square kilometers were burned. A century has passed since the Tunguska Big Bang, and the local forest and ecological environment have been restored. This incident is suspected to be the work of nikola tesla, but there is no evidence that Tesla has anything to do with it.
