谷物的极化带电特性

对6个品种的谷物进行了极化带电的测定。从电化学和生物学的角度,解释了谷物极化带电的成因,建立了谷物极化带电特性的模型。研究表明谷物的带电过程可以分为残余电荷过程、极化电荷过程、极化饱和过程和电晕充电过程。谷物的极化带电量与其品质有关。

Study on Polarization Charge Property of Grain

The polarization charge property of grain is one of the electrical properties of grain. The study on it made an important impact on electric treating, clearing and grading of grain. The determination of the polarization charge property of grain was carried out by using the experiments of 6 breeds of grain, the reasons for the polarization charge of grain were explained theoretically and the model of the polarization charge property of grain was presented. The study showed that the grain charging process consisted of remaining charge process, polarizing charge process, saturated charge process and charging process, and the amount of the polarization charge of grain related to its quality.
