About 93% of the Earth's surface is covered by oceans, which makes our exploration of the oceans quite slow.
In order to gradually realize the in-depth exploration of the ocean under modern technological conditions, deep diving technology came into being.
It can be seen that the deep submersibles currently owned by countries around the world have gradually become the frontier of scientific and technological competition.
Looking at the international scientific and technological competition pattern, it can be seen that the United States, Japan and other countries have always occupied a dominant position in deep diving.
However, now, the mainland has also made some breakthroughs in deep diving technology, so what is the gap between the deep submersibles of China, the United States and Japan?
United States – the foundation for leading the way in deep diving technology.
As we all know, during the Cold War, if United States wanted to seize the leading position in science and technology from many countries, it had to be better in science and technology research and development.
At that time, the United States process of developing and developing a deep-sea submersible was full of twists and turns, and finally United States the world's best-performing deep-sea submersible at that time, the "Trident".
The deep-sea submersible was also specially built for the needs of United States in the struggle for world supremacy with the Soviet Union during the Cold War.
It can be seen that United States has very high expectations for the "Trident" submersible, and at the same time, this submersible has also pushed the development of United States's deep diving technology to a peak stage.
However, after the Cold War gradually passed, with the changes in the international situation, the demand for the "Trident" deep-sea submersible seems to have gradually disappeared, and similarly, this deep-sea submersible has also lost the objective conditions for updating and iterating.
The Trident mainly dives to a depth of 11,970 meters, so the United States created a new deep submersible called "Alvin", but it can't even surpass the just-released "Trident", its maximum depth is 7620 meters.
Although the Trident and Alvin both set new world records at the time, there were no new deep submersibles in the United States since then.
So why did the new submersible not be updated and iterated later when there were already good technical conditions at that time?
Ultimately, this has to do with United States's own technological limitations.
United States scientists have experts in deep-sea physics, but there are no scientists in biology, and some scientists in materials science.
After all, there are great differences between these fields, and it is undoubtedly quite difficult to improve United States' own deep diving technology.
Wouldn't it be a waste of time to involve people in the United States who study biological components in the deep sea?
Therefore, due to the lack of scientific research strength of the United States, it can only entrust this task to other countries, which also reflects that although the United States can be at the forefront of the world in many fields, it cannot maintain a strong enough development momentum in many aspects.
Because of this, United States technology has gradually lost its dominance in the process of continuous development.
It can be said that the development of deep diving technology in United States can reach the top of the industry, mainly relying on the global scientific and technological development level at that time.
However, as various scientific disciplines in the world have come out of the process of prosperity and development, the mainland also has a great advantage in scientific research.
But at the same time, Japan has also achieved some results.
So what is the level of development in Japan?
Japan – Design is more rational.
Although Japan's economic strength has been sluggish in recent years, it still develops various advanced domestic technology levels, and with the continuous efforts of domestic scientific researchers, they have finally manufactured a new type of deep submersible called "Shenlong".
Among them, there are some outstanding talents, who have pushed the limits of their own research and development time and time again, and finally succeeded in developing this new deep submersible capable of diving 6,500 meters.
However, at this time, China also joined the deep diving research and development and developed the Jiaolong, but compared with the Shenlong developed by Japan, the Jiaolong is nearly 4,000 meters ahead of the Shenlong.
This is mainly because Shenlong, as Japan's own experimental deep submersible, was not easy to study under the technical conditions at that time, and it can be described as very difficult.
However, Shenlong always seemed to be a little short of its design goal.
As the years passed, Japan moved no longer limited to Shenryu and achieved an even greater breakthrough by creating a new generation of manned deep submersibles called Shingen, which was dedicated to the development of marine resources.
The maximum dive of the Jinxian is 6,100 meters, and when it was first designed, the limit of the dive was 7,000 meters, so this shows that Japan's design level is relatively rational, which is a very rare point.
Jinxian is actually the most advanced manned deep submersible in Japan at this time, and its scientific research value is relatively high.
Although in the 70s of the last century, Japan developed a manned deep submersible - Kagagetsu, which achieved a 5100-meter deep diving record at that time, laying the foundation for Japan's later research on higher-performance manned deep submersibles.
However, although Japan has been working on new manned deep submersibles of various types and superior performance since the 70s of the last century, at present, Japan's newly developed Jinxian has not met its scientific exploration needs.
Japan new type of deep money is only a breakthrough in the previous technical conditions, but it has not reached a new height, and it is also not as good as the previous United States developed Avidon diving performance, which highlights the role of the mainland in this regard.
China is a domestic innovator who has achieved a number of new world records.
In fact, China is a well-known late starter in this area, but in recent years, the mainland has not only achieved a number of new world records through its own independent innovation, but has also gradually taken the lead in many aspects.
Comparing the Jiaolong developed by the mainland with the previous two countries, we can see that the Jiaolong created a new record of 7016 meters, in which the Jiaolong not only uses high-strength carbon fiber composite materials and high-strength steel shells, which can effectively resist high-pressure environments, but also carries a variety of sensor systems and scientific instruments, which can monitor and collect data on the seabed environment, conduct a comprehensive and detailed exploration of the seabed environmental information, and realize the information we most want to know about the marine environment.
Jiaolong is an important game of chess in the development of manned deep money in the mainland, but the hardships will not be mentioned for the time being, after which the mainland has independently innovated and developed a new manned non-powered multi-purpose large globe marine scientific research platform called "Struggler".
The biggest highlight of the platform is that the diving depth can reach 10,909 meters, which is the manned submersible with the largest diving depth, which not only has both scientific research and commercial benefits, but also can well promote the development of the mainland's marine economy, and establish a new channel for the mainland to engage in marine scientific research and resource development, which is of great significance.
To a certain extent, Endeavor can greatly promote the exploration and development of continental marine resources, and it also provides an important means for mainland scientists to explore the seabed and study the existence of life in special environments, and at the same time, it can help us further understand the earth's interior and marine geological structure, which is of great significance for understanding the entire ecosystem.
epilogue
It is really obvious to all that the mainland is now able to develop such a manned unmanned power multi-purpose large-earth ritual, and it is realized by the ability to gather resources under the reform of our national system.
Jiaolong and Struggler are undoubtedly a new starting point for marine mining and scientific research on the mainland, and will definitely carry out further research and development in the future, while Struggler is undoubtedly also a new starting point path, which will help to form other aspects of research such as ecosystems, so the future can be expected.
