Meanwhile, the clamp circuit will limit the output voltage or current at a fixed value when they are abnormal that caused by a DUT short circuit or other fault in order to protect the device.

当被测dut发生短路或其他异常导致电流或电压过高时，钳位电路会将输出电压或电流限制在一个固定值上，以保护器件不被损坏。

The results show that in Wutai, Yanmenguan and Linfen, the stress values have not reached the critical value, whereas in Yuncheng area, the values have reached the lower limit of the fault activity;

分析结果表明， 总体来看， 目前五台山、雁门关和临汾地区的水平主应力都未达到断层活动的临界值；
