The most fundamental reason for this incident is the U.S. government's sanctions and repression against China. The specific reason is that the company where the software is located stopped its authorized service to Harbin Institute of Technology. Recently, the National Modeling Committee had to ban the students of Harbin Institute of Technology from using the software. Because once used, it will involve unauthorized use of piracy and may face legal problems.

First of all, from the perspective of the US government, the United States listed many 985 colleges and universities including Harbin Institute of Technology on the entity list last year. Universities on this entity list will be restricted by the US government in many areas, including their students studying abroad or buying scientific research equipment. Affected by many things. This time, Harbin Institute of Technology was banned from using a certain mathematical software, which is an obvious example. Just at the beginning of the first half of this year, the US government asked the company where the mathematical software is located to stop authorizing the software to Harbin Institute of Technology, which means that Harbin Institute of Technology will not be able to use the software publicly, which means that its academic research field or other aspects will not be able to use the tool. However, in the field of data simulation and numerical analysis, the position of this software is irreplaceable.

The American government tried to restrict the development of Harbin Institute of Technology in this way. As one of the top engineering colleges in China, Harbin Institute of Technology has made outstanding academic contributions and important academic status in aerospace, computer science and other fields. Software plays a decisive role in these fields. However, if the software can't be used, it means that many of its research results can't be published normally, which is very unfavorable to the researchers of Harbin Institute of Technology. For the students of Harbin Institute of Technology, it is also a very unfortunate news that they can't use this software to participate in the national mathematical modeling competition. Because in the modeling competition, the frequency of this software is as high as 95%. To put it bluntly, the main reason is that the United States tries to restrict the development of universities in China and China.

In any case, if the United States restricts us in this way, it will certainly inspire the confidence and determination of China people to independently research related technologies. I hope that the researchers and students of Harbin Institute of Technology can face up to the difficulties and forge ahead. I also hope that some politicians in the United States will wake up at an early date and that peace and development are the themes of this era.
