At the beginning of this century, China invested more than 250 billion won in the construction of the Three Gorges Dam, which attracted the attention of the world.
The construction of the Three Gorges Dam has become one of the largest water conservancy projects in the world, bringing huge economic and energy efficiency to China every year.
Many countries around the world are salivating over the project, and the United States has even openly questioned whether the Three Gorges Dam could be easily destroyed. "As long as there is a ground-penetrating bomb, the Three Gorges Dam will be shattered in an instant. "
The Americans assert so, but they clearly overestimate their own strength and underestimate the progress of science and technology in our country.
The construction of the Three Gorges Dam is of extraordinary quality, and there is no need to worry about being easily damaged. Among them, a young scientist named Ouyang put in the effort, which is indispensable.
Ouyang graduated from the China University of Engineers and Engineers and is an expert specializing in physical defense technology.
In 1999, when the US military bombed China's embassy in the Federal Republic of Yugoslavia with a new type of drilling bomb, young Ouyang was in his prime year.
In a fit of rage, he participated in a scientific research project on the technology to crack the diamond bullet.
Due to his expertise and passion for serving the country, Ouyang decided to use concrete, a highly integrated building material, to achieve effective defense. Despite the difficult road, Ouyang never gave up his passion for scientific research. He is well aware of the historical responsibility he shoulders.
The ground-penetrating projectile used by the U.S. military is an extremely threatening projectile that can penetrate the surface in a very short time, more than 20 meters underground, and in a predetermined position**. John F. Kennedy).
This missile is designed to be very ingenious and can effectively evade the defenses on the ground, causing a lot of damage to the target.
For our country, the existence of such missiles is undoubtedly a great security danger. Because it can easily destroy our military bases, command centers and other important facilities.
In order to cope with these challenges, our country quickly organized a special group of the best scientific researchers to study how to confront the ground-penetrating bomb. Among them, Ouyang is one of the core members of this team.
He was well aware that in order to successfully protect against the attack of ground-penetrating shells, it was necessary to find strong and tough materials, build fortifications.
But this material is not common in nature and requires a lot of experiments and research to find.
Wu Xi and his team embarked on a long search trip. They collected samples of hundreds of possible materials from various metals, ceramics, composites, and more.
Each material undergoes rigorous testing and evaluation to enable them to meet the requirements for drill resistance. The process was full of hardships and challenges, but Wu Xi and his team never gave up.
In the midst of a failure and setback, they accumulated valuable experience and gradually found the right direction.
Eventually, in important experiments, they discovered special concrete formulations that not only had extremely high hardness, but also toughness.
When impacted by an external force, it can absorb and disperse the impact force to prevent direct penetration of the drill projectile.
The discovery left Wu Xi and his team ecstatic. They immediately put in an intense optimization effort, constantly adjusting the composition and proportions of the concrete to improve performance.
After countless tests and improvements, they finally developed concrete with excellent performance, and the compressive strength is more than 6 times that of the American Jedam bomb.
This means that even the most powerful ground-penetrating projectile will not be able to penetrate this concrete defense.
In 2002, Ouyang won the first prize of the military for this epoch-making invention. He became a rising star in the field of defense science and technology. We want to ensure that experts like Ouyang have made significant contributions to the country's scientific and technological progress.
It is the generations of scientists who have the heart to serve the country and are not afraid of difficulties that have created the rise of the Chinese nation.
Wu Xi and many other similar experts and scholars have continuously promoted China's scientific and technological development and enhanced their strength in national defense scientific research with their professional knowledge and enterprising spirit.
Their contributions have enabled our country to occupy the strategic high ground in important areas and defend the dignity of the country.
We must inherit and carry forward the spirit of scientific research experts and lead the great rejuvenation of the Chinese nation with scientific and technological innovation.
