1·In the investigated temperature range, the conductive mechanism ofr all samples belongs to the variable range hopping conduction of the polarons.

在所研究的温度范围内，所有材料的导电机理都属于极化子的变程跳跃导电。

2·The hopping conduction in energy gap of amorphous semiconductors at low temperature is explained by calculating hopping probability when an electron hops from one defect center to the other.

通过计算电子由一种缺陷中心向另一种缺陷中心的跳跃几率，解释了非晶半导体中的低温带隙跳跃导电问题。
