These types of heat flux have a wide range of applications in scientific research, industrial production, and daily life. For example, in industrial manufacturing, the temperature of the material throughout the processing process needs to be tightly controlled to establish the desired properties and quality control, which involves the precise measurement and control of heat flux.

Excessive residual chlorine in swimming pools can have many negative effects on human health and water quality safety. Therefore, swimming pool operators should strictly control residual chlorine concentration in accordance with national standards, regularly test water quality, and take effective measures to ensure water quality safety to protect the health and safety of swimmers.

External environment
External electromagnetic interference, noise, etc. will interfere with analog signals. In the vehicle environment, the electromagnetic interference signals between the cables of different components are coupled with each other, and in extreme cases, the interfered components will fail. In the BCI test, the strong electromagnetic coupling generated by the large current injection in the field environment will interfere with the transmission of analog video signals.

Industrial wastewater COD treatment technology
If the high chemical oxygen demand (COD) in industrial wastewater is discharged directly without treatment, it will cause water hypoxia and promote excessive algae growth. Therefore, appropriate treatment technology is needed. At present, the common industrial wastewater COD treatment technologies are mainly the following:
