triboelectrification

The scientist obtains from the phenomenon, triboelectrification's essence is①The different material's atomic nucleus bound electrons' ability is different.

从现象中科学家得到，摩擦起的本质①物质的原子核束缚子的本领。

The study showed that the property of grain triboelectrification relates to grain moisture, friction velocity, dielectric constant and friction material.

研究表明，谷的摩擦带与谷含水率、摩擦速度、谷的数以及摩擦材料等因素有关。
