这样检测系统只要测量出谷物的介质损失角，单片机通过查表和计算即可获知谷物的水分含量。

If only dielectric loss Angle of grain was measured, the measuring system can get grain moisture content by seeking table and calculating.

电气设备绝缘预防性试验中的介质损失角正切的测量，则是一种使用较多而且对判断绝缘较为有效的方法。

The measurement of dielectric loss angle is one of the main methods in the preventive tests for the insulation of electrical equipment.

通过对传感器的标定并进行相应的回归处理，可得到介质损失角和谷物水分的函数关系，并将此函数关系存入单片机的存储器中。

Through demarcating sensor and corresponding regress manage, can get relation between dielectric loss Angle and grain moisture content. The relation was stored to memory of single-chip computer.
