prebreakdown current

The waveform controlled dc was applied to the sensor and the prebreakdown current flowing through the sensor was measured by the picoammeter.

制作了一种纳米尖端场离子化气体传感器,以氧化锌纳米尖端为阳极,钨针为阴极,采用皮安表向传感器提供输出波形可控的直流电源,测量流过器件的预击穿电流。

Then,through analysing the value of breakdown current of series resonant device with variable frequency,it is considered that the breakdown current wouldn t hurt the object under test further.

重点分析了调频式串联谐振耐压装置现场试验时可能出现品质因数Q值上不去的原因及相应的防止措施,对该装置耐压试验击穿电流进行了详细的分析,指出其对被试品不会造成进一步的损伤。
