Bipolar junction transistor ( BJT) has the self-heating phenomena, which seriously affects the properties of transistor. 对于双极性晶体管,由于自身存在的自加热现象,严重地影响着器件的特性。
Based on junction phenomena over debris areas, types and features at conflux of different areas are obtained. 本文首先研究了整个泥石流流域上发生的汇流现象,从泥石流产生区、流通区以及堆积区对泥石流汇流的形式和特点进行了总结。
