The program of predicting temperature and humidity in deep coalmine;

The paper introduced the importance of humidity detection inside a drying chamber, its detection device and methods.

This paper introduces the methods and matters needing attention of g as pressure detection, moisture measurement and gas management of SF6 totally en closed combinative electrical equipment.

The text gives us an introduction on an apparatus of cotton moisture measurement, in which based on SCM PIC16C74 and moisture sensor HM1520.

The paper elaborated a new theories which include both“the dual parameter technique” on method of a density independent microwave moisture determination with a loose grain and “the microwave resonator technique” of a dimensions independent and shape independent for the single kernel grain moisture measurement.
