current amplification factor

基本解释

At a higher injection level, the current amplification factor drops off as the emitter current density is increased.
一个是在给定的注入条件下如何保证足够大的电流放大；
In the design of an emitter of power transistors, the main problem is to attain good current amplification factor β for a given injection level.
本文讨论功率晶体管设计中设计发射极时所需考虑的两个问题。
Based on the model, the variations of the electrical parameters such as the potential barrier, the anode junction voltage drop, and the current amplification factor are studied and discussed.
在该模型的基础上，讨论了势垒、阳极结的电势降落和电流的放大因子等电参数的变化。

Therefore, the CO2 amplification factor might have contributed proportionately much more influence than today, causing it to be less relevant to current circumstances.
