辐照后基极电流、结漏电流增大，集电极电流、击穿电压减小。
The base current and the junction leakage current increase, while the collector current and the breakdown voltage decrease for SiGe HBTs after radiation.
晶体开关管的集电极与发射极间的电压取决于电网电压。
The collector voltage of the switching transistor is determined by the voltage of the power network.
在最佳工作条件下，给出了集电极电流和集电极——发射极电压波形。
The waveforms of the collector current and collector-emitter voltage are also determined under the optimum operation condition.
如果另外有个电压或电流源存在，用仅有减小电流作用的集电极开路开关代替s1。
If another voltage or current source is present, you could replace S1 with an open-collector switch that sinks current only.
