It was learned on the spot that 18 is a postdoctoral research project, and most of the experiments were done by graduate students. Only this laboratory in the building is doing experiments.

On the evening of February 23rd, 65438, Tsinghua University released the police's preliminary conclusion that the experimental hydrogen bottle accidentally exploded and caught fire, resulting in Meng Xiangjian's leg injury and death.

At 2 pm on 23rd, Meng Xiang, a postdoctoral fellow who died in Tsinghua, sent a long microblog to his relatives, announcing their understanding of the progress of the explosion in the laboratory.

According to the blog post, it can be confirmed that Meng Xiangjian's experiment that day was a catalytic hydrogenation experiment, which he called a conventional experiment. Moreover, after the observation of the family members at the scene, Meng Xiangjian's console only showed signs of burning, and there were no signs of explosion. The reaction kettle marked with Meng Xiangjian's name was intact.

According to the article, the family learned on the third day after the incident that the explosion occurred in a hydrogen bottle. The explosion point was two or three meters away from Dr. Meng's console, and the bottom of the bottle exploded. The original length of the cylinder was about one meter, and only the upper part was about 40 cm after the explosion. According to the blog post, it is understood that the thickness of the cylinder is one centimeter, which shows that the explosion power was huge at that time.
