Rebirth of science and technology academic master

In order to celebrate Qin Yuanqing's family returning home to visit relatives, and also to celebrate Qin Zheng and Qin Shiman winning the Olympic gold medal, people in Qinjia Village and the entire town set off fireworks today.

Even the gods, which only appear during the Lantern Festival, were carried out by the villagers. Young people held torches and began to carry the gods around the mountains and villages, while every household was setting off firecrackers, fireworks, and dancing on the fire. The rising gifts were A brilliant light bloomed in the night sky, illuminating the smiles on everyone's faces.

"Grandpa, grandma, I will set off the fireworks. My brother and I will set off two each!" Qin Shiman said, and then volunteered to set off the fireworks.

Everyone else was setting off fireworks, and Qin Yuanqing's home was no exception. They even prepared more than two hundred fireworks at home, ready to bloom tonight.

Qin Shiman and Qin Zheng seemed to have a tacit understanding. They held a lighter and lit the fuse with excitement on their faces. The sparks made the two of them light a firework. They both screamed and quickly backed away. However, Extremely happy, looking at the sky excitedly.

In the capital, wherever they have the opportunity to set off fireworks, they always watch the fireworks through videos, but watching the videos is not as exciting as setting off the fireworks in person.

I saw two big fireworks continuously launching into the sky, blooming colorful gifts. Each of these fireworks has 128 rings. The height of the fireworks is high and beautiful. Suddenly, I became the most beautiful cub in the village. Even The whole town could see the fireworks and couldn't help but look over.

Some people say that setting off fireworks is a waste of money and will pollute the environment. It is a thing that harms others but does not benefit oneself. They suggest that it should be completely banned! But in Qin Yuanqing's view, although it has some disadvantages, it is a kind of traditional Chinese culture. Whether it is New Year or special festival, without fireworks, the flavor will be missing. For example, cities ban fireworks, resulting in a deserted Spring Festival and no New Year atmosphere.

The children at home were all admiring the fireworks. After the fireworks were set off, they lit new ones again. The children took photos of the fireworks and sent them to their WeChat Moments.

When the gods arrived, there was a climax of fireworks. Fireworks were placed along the road. More than a hundred fireworks were lit and then bloomed in the sky. Parents took their children to burn the statues of the gods. Fragrance, make a wish.

In southern Fujian, there is a tradition that one should chase gods rather than stars. If you ask a Hokkien person to get up at 6 o'clock to chase stars, it's impossible. If you ask him to get up at 6 o'clock to worship the gods, he will be there at 4 o'clock. Take a look at the grand ceremony of worshiping gods during festivals every year. It is definitely ten times more lively than the star-chasing scene. Take a look at which of the more famous temples and Taoist temples. During the festival, the traffic jam can be blocked from the foot of the mountain to the top of the mountain.

Qin Yuanqing used to think that this was superstition, but when he grew up, he realized that it was the sustenance of the soul and the starting point of kindness.

Qin Yuanqing was moved in his heart. Although today is also the 15th of July, a traditional festival, Qin Yuanqing remembered that it had never been so grand. He knew that this was the villagers' way of expressing their warm welcome to him, and it was nothing more than his dedication to his hometown. He did some trivial things, and the villagers remembered him well.

There was even a cannon-like salute over the scenic area, a total of 256 shots, and each shot was like earth-shattering.

It was not until 12 o'clock in the evening that calm was restored, and Qin Yuanqing and the others returned to the house. Qin Zheng and Qin Shiman were full of energy and did not feel tired even at 12 o'clock. They wanted to continue watching TV, but Qin Yuanqing drove them to bed.

After a trip back to his hometown, three days passed in a blink of an eye, and Qin Yuanqing's family of four had to say goodbye to their reluctant relatives and embarked on a journey back to the capital.

As the team champions of this year's Olympic table tennis events, Qin Zheng and Qin Shiman need to participate in a series of activities to promote the Olympic Games, the national team, and the national table tennis team. This is their responsibility and obligation as athletes. And Qin Yuanqing also embarked on his own busy journey.

After the journey of earth-moon migration, the 'Chang'e 18' probe arrived at the moon. Along with the 'Chang'e 18' probe, there was also a Lunar Rabbit rover and a life capsule. This time the 'Chang'e 18' probe The spacecraft has three missions. One is to further explore the resources and climate of the moon. The other is to lay the foundation for the third scientific research station for the third manned lunar landing. The other mission is to carry the mined helium 3 back to the earth.

Nowadays, all aspects of the 'Double Ring Space Station' project are progressing steadily, and every link is carefully considered. Now even the modular construction has completed all demonstrations, and everyone is working hard to promote this unique project. A historic space feat.

Rongcheng, China Space Laser Research Institute, is a military equipment research and construction institution. It is China’s most authoritative and technically capable institution in laser weapon research. It is a military secrecy research institute. Ordinary people don’t know anything about this institute. I don’t know, but anyone who comes close to the walls of this institute will be arrested and examined.

In 1979, China decided to develop laser weapons because at that time, the United States had successfully experimented with using lasers to hit satellites, which made China realize that in the future, lasers could be used to hit tanks, satellites, and airplanes. In the future, air warfare will be the era of lasers, and space lasers Era, its cost is lower than other weapons.

Since the launch of the 'High-tech Research and Development Plan' in March 1986, which is also the legendary "863" plan, laser technology is one of the subjects in the 863 plan, and the China Space Laser Institute was established under this background , which has gathered a large number of experts in the laser field in China to develop space laser technology. It is thanks to the efforts of countless scientific researchers that China has mastered five core technologies when it first entered the 21st century: laser material technology, laser radiation material physical mechanism and imaging map technology, one-time rapid tracking positioning control technology, laser imaging technology and high-density energy reversible conversion carrier material technology.

As early as around 2010, China already had many world-class laser weapons. China was a world leader in laser research. For example, China had long been a world leader in theoretical research on quantum dot lasers. China's ultra-powerful solid-state laser is also world-class. The laser beam it emits can obtain an energy answer of 35K joules per square centimeter at a distance of 3,000 kilometers. This energy density is nearly 1 higher than the damage required to attack a missile. orders of magnitude or more.

The laser cannon mounted on the "Shenlong" aerospace aircraft K1 was built by the China Space Laser Research Institute. It uses controllable nuclear fusion as energy. The laser cannon weighs 3 tons and has an effective lethality of more than 50,000 kilometers. It can be said that once Once it enters space, no weapon known on earth, including missiles, can threaten it.

As for the laser defense system deployed on the ground, it was also built by the China Space Laser Research Institute. A total of 10 laser defense positions were built in China, forming a full-scale laser defense system.

At present, Huaxia is at the world's leading level in CO2 laser, chemical laser, free electron laser and X-ray laser.

Qin Yuanqing came to the China Space Laser Research Institute this time to explore whether it is possible to build a laser that can be deployed directly in space to strengthen the protection of the "Double Ring Space Station".

"Academician Qin, the ultimate laser weapon we can achieve now is 3 tons. This still has controllable nuclear fusion that can provide powerful instantaneous super energy." Wang Gang, director of the China Space Laser Research Institute, hesitated for a moment and said in embarrassment. Said: "You also know that to be able to achieve this step, you have already provided many new technologies and new materials, as well as controllable nuclear fusion as energy. Otherwise, the laser weapon would still be very large, even 10 tons. Previously, they were all equipped in fixed locations on land or on warships.”

"If you want to deploy it on a space satellite, it's so big." Wang Gang didn't say any more, but the meaning was self-evident.

If you want to deploy laser weapons on satellites, you have to solve two problems. First, the size and weight of the laser weapons must be reduced to at least 1 ton. But this alone is not enough, you also need a powerful instantaneous super energy battery. But now the only thing that can provide such powerful energy is the 'Golden Crow Device'. Even if the 'Golden Crow Device' is miniaturized, its size and weight are not small. Add it all up. Satellites simply cannot satisfy this requirement, and there are also control issues involved.

"Director Wang, what if laser weapons are deployed on the moon?" Qin Yuanqing put forward an idea.

"It is of course possible to install international lidar on the moon. We have proposed such an idea before. However, there is a problem. If the opponent uses laser weapons to attack the 'Double Ring Space Station', it will be difficult to defend in time." Wang Gang frowned slightly. said with an eyebrow.

Although China is at the forefront of the world in terms of laser weapons and is at the world's leading level, you must know that laser weapons are not only possessed by China. The United States, Russia, France and other countries also possess "laser weapons", and "laser weapons" are so fast The speed is very difficult to guard against. Coupled with the huge size of the 'Double Ring Space Station', to be honest, it is simply a living target. As long as the laser weapon is not too bad, it will be accurate every time.

This is also the reason why many people opposed the establishment of the "Double Ring Space Station" at the beginning, because once it is hit by "laser weapons", the "Double Ring Space Station" will be useless, and the losses caused by this will be extremely shocking. Yes, even if the Huaxia family has a great business, it cannot afford such losses.

Qin Yuanqing frowned slightly. Although the overall situation is now under control, the world is still a bit turbulent. Some precautionary measures must be arranged first to prevent someone from jumping over the wall in a hurry, which would be very bad.

But what Wang Gang said is also true. This is a bottleneck that laser weapons currently encounter. It is not easy to break through this bottleneck.

"Do we need to destroy the laser weapons in other places before construction?" Qin Yuanqing murmured to himself in a low voice, showing a thoughtful look.
