With the implementation of a series of key engineering projects, the instrumentation industry is increasingly receiving attention and support. This will make the market investment value of the instrumentation industry increasingly prominent. But in the past year, there have also been many major events in the instrumentation industry. CCTV hosts have self funded research on PM2.5, but the data has been questioned; & ldquo; Water Ten& rdquo; After countless calls, it emerged; Overseas acquisition of internal instrument companies; The dark matter detection satellite developed by my scientist has been launched into space; Laboratory safety is crucial, and fire monitoring devices are indispensable; Frequent meetings related to instrumentation are held, and so on. Below, I will summarize them together with everyone. CCTV host Chai Jing's release of "Under the Dome" data has been questioned, and the reliability of related testing equipment and data is urgently needed. In March of this year, Chai Jing, who resigned from CCTV, released an in-depth public welfare survey titled "Chai Jing Haze Investigation: Under the Dome". In this promotional video, Chai Jing used a large amount of data and information to support her conclusion. The doctoral thesis of a netizen on Zhihu happened to be related to emissions, and he felt that it was a bit wrong. After checking the information, he found that almost every data had problems. Firstly, there was a deliberate confusion between haze and PM2. 5. Secondly, there is a lack of testing range and sensitivity data of the sampling instrument, air humidity and wind direction conditions, flow data of the sampling instrument, as well as the background and time of changing the data caliber to form misleading impressions and tampering with information. This report has made netizens exclaim: it's better to leave professional matters to professionals!
