对结发热最敏感的两种测试是正向电压测试和漏电流测试。
The two tests susceptible to junction heating are the forward voltage and leakage current tests.
源表首先进行必要的直流测试，例如正向偏压、反向击穿电压和漏流。
The SourceMeter instrument first performs the necessary DC tests, such as forward voltage, reverse breakdown voltage, and leakage current.
此外还观察到，在较低的测试频率和较大的正向电压下，激光二极管的结电容具有负值。
A negative capacitance effect in LDs is also observed under larger voltages or lower frequencies.
