Well, the α ratio works similarly: if emitter current is held constant, collector current will remain at a stable, regulated value so long as the transistor has enough collector-to-emitter voltage drop to maintain it in its active mode.

系数α的作用与之类似：如果发射极电流保持恒定，只要集电极－发射极电压足以使其保持在放大区，集电极电流也将稳定保持。

The further away from the thermoneutral zone that the environmental temperature moves, the more energy the endotherm has to expend to maintain
