Overview and parameter description of medical X-ray collimator

“After conducting the experiment, I have the confidence and the evidence to say that Lianhua Qingzhen is really effective.” On the evening of May 4, Zhong Nanshan, academician of the Chinese Academy of Engineering, was invited by the Ministry of Foreign Affairs and the National Health and Welfare Committee to answer the “epidemic” solution for international students Said when confused.

Zhong Nanshan said that there is sufficient evidence to prove that Lianhua Qingwen is effective in the treatment of new coronary pneumonia. He reminded international students that if they have a fever, drink plenty of water and eat some medicines taken in the past, such as Baifuling and ibuprofen.
