Add water to the sterilizer (almost to the barbed wire, don't add too much) Put in the utensils to be sterilized, culture medium, etc., the test tube of the petri dish should be wrapped first, and the mouth of the medium bottle should be tied firmly Cover the pot, if it is an automatic steam sterilizer, you can start it with a good time, if it is manual, you should heat it for a period of time and wait for the air in the pot to drain and then close the high-pressure valve, the time and temperature are the same, and then open it after the temperature drops down after the sterilization is over.

China's chip is a hurdle that all Chinese IT elites can't overcome, but Deng Zhonghan has silently stepped through this hurdle. In 1999, Vimicro was established, and in July 2001, it launched "China's first chip" - "Starlight No. 1" chip for digital imaging, and successfully realized marketization and entered the international market. Of course, these are just the beginning of Deng Zhonghan and Zhongxingwei, after which Zhongxing Micro launched "Starlight No. 2", No. 3 and No. 4. >>>More
