2,400 meters is the length of four 800-meter runways, the height of 800 floors, the altitude of Lijiang, and nearly a quarter of the height of Mount Everest.
The above are all 2,400 meters above the ground that we can witness, so what kind of surprises will it bring us if it is 2,400 meters deep underground?
The Jinping Underground Lab we are going to talk about today will bring the answer.
In 2003, the state originally planned to build a hydropower station in the Yarong River area of Liangshan Prefecture, Sichuan, but due to the special terrain of the area, it finally planned to build an underground laboratory here to facilitate scientific research.
The Jinping Underground Laboratory has a feature that other laboratories do not have, and its rock cover is deeper.
Because of this, the space in the laboratory has been increased, so that the range of activities of the experimenters has increased, and it has also allowed them to have enough space to store water and electricity resources.
In addition, because of the increase in space, the underground transportation of the laboratory is more convenient and the infrastructure is more perfect.
In December 2023, the second phase of Jinping Underground Laboratory was also successfully completed.
This time, it is no longer limited to Tsinghua University and Yalongjiang Company in the first phase of the project, but has welcomed more project teams.
In addition to various universities, there are also research institutes and ecological groups that have settled in the underground laboratory.
The continuous breakthroughs and progress again and again have witnessed the steady improvement of our country's scientific and technological level and independent scientific research capabilities.
Although the Yalong River valley has steep terrain, it is precisely because of this characteristic that it has become the core area of hydropower development in the mainland.
Of all the sections, the Jinping area is an unprecedented challenge due to the heavy rock formations due to the terrain.
But it was our perseverance that turned this difficulty into a scientific miracle.
It is precisely because of these rocks that the laboratory can be completely covered, forming a perfect space environment shielding cosmic rays, so that the cosmic ray flux of the laboratory is only 1% of the surface, which is an irreplaceable experimental site.
This is one of the reasons why the laboratory is located 2,400 meters underground.
The large underground space and the long distance between different "equipment and projects" make it less susceptible to interference from other electromagnetic fields, and more accurate experimental data can be obtained.
Moreover, the temperature and humidity of 2400 meters underground are more suitable for the use of some experimental equipment. And most importantly, the underground is relatively safer and can avoid some unnecessary radiation infestation.
We all know how difficult it was to build the Jinping Underground Laboratory, which was paid for by the efforts of countless workers day and night.
The difficulties and challenges they encountered in the construction process may never be imagined by ordinary people, and it is precisely because of their spirit of excellence that even the decimal point may have to be calculated and verified countless times before today's success and the Jinping underground laboratory 2,400 meters underground.
The completion of the Jinping underground laboratory has allowed countries around the world to see China's rapid development of scientific level, and at the same time, it has also allowed our scientists to no longer rely on others and conduct relevant scientific research more conveniently, which will help the mainland's scientific and technological level to the forefront of the world.
In addition to conducting routine scientific research, the Jinping Underground Experiment is also an educational base.
Every year, students or scientists from all over the world come to Jinping Underground for experiments, exchange and learn in this place full of science and technology, and even explore unknown areas together.
Indirectly, it has become a bridge between the mainland and the world.
More importantly, the Jinping underground laboratory can show the mainland's scientific progress in recent years and its ambition in scientific research from many aspects, marking the important role of the mainland in the world's scientific research, allowing more and more people to see China and making every Chinese have a sense of pride.
The strength of a country is not only reflected in the economic and military aspects, science and technology are also an inseparable part of the country.
Although the development of science and technology needs to rely on the country's economic foundation and inject sufficient scientific research funds, scientific research is something that human beings can never let go.
Therefore, the mainland can successfully build such a high-level underground laboratory. Its success is not only to demonstrate our strong scientific and technological level, but also to prove our scientific and technological capabilities to the world.
epilogue
If every laboratory is compared to a fertile piece of land, then scientists are "cultivators", who are constantly trying to innovate with their own abilities and methods to make the most of this "land".
Through the efforts of generations of scientists, we would like to believe that in the near future, one laboratory after another will appear, and when the time comes, they will contribute to the development of mankind together with the Jinping Underground Laboratory.
