The low frequency digital phase reflectoscope reflector in the industrial field is the general measuring tool which uses frequently, for instance the electrical network incorporation switches on when the electrical power system, requests two electrical network's electrical signals to be the same, between this request precise survey two power frequency signal phase difference.

低频数字式相位测试仪在工业领域中是经常用到的一般测量工具，比如在电力系统中电网并网合闸时，要求两电网的电信号相同，这就要求精确的测量两工频信号之间的相位差。

Other related studies showed that the hot carrier effect existed a transition point, which reversed the dependence of MOSFETs' Ib to temperature. This finding was proved with the peak substrate current would reverse its temperature dependence when biased drain voltage Vd across the transition point.

其他的研究指出，热载子的效应存在著转位点，我们把电晶体闸极偏压在基板电流的最大值，汲极偏压在转位点的上下，会造成基板电流与温度效应之间的关系反转。
