DC Signal IN

For the problem of signal current bypass with track circuit of rolling stock depot in DC electric traction sections, the paper provides measures to prevent it.

针对直流电力牵引区段车辆段轨道电路中的信号电流存在的迂回问题，提出了在工程设计中的防范措施。

By comparing the heating effect of an unknown AC signal to that from a known DC reference, metrologists can determine the RMS AC quantity (voltage or current) in terms of the DC quantity.

为了对比一个已知直流参考的未知交流信号热效应，计量人员可以确定在一段时间内直流的交流有效值(电压或电流)。

If the AC voltage at the input is large, part of this signal is rectified, producing an error in the DC signal being measured.

如果输入端的交流电压很大，其一部分信号被整流，于是在被测的直流信号中产生了误差。
