电路

• The plant is operated entirely by remote control and monitored by closed circuit television or periscope .
  这个工厂完全用遥控操作，而且用封闭电路电视或展望镜来监视。
• When the secondary circuit is closed, both primary and secondary currents set up a flux in the core .
  当次级电路接通时，初级电流和次级电流都在铁芯内建立了一个磁通量。
• The electrical and gas circuitry for the fullbin dryer is similar in many respects to that of a household furnace .
  整仓干燥机的电路和燃气管路在许多方面与生活用炉相似。
• We close this chapter on resistive circuits with a brief introduction to the subject of electrical measurements .
  我们结束电阻电路这一章时，简短地介绍一下电气测量问题。
• Physical units transmit information to and from the microcomputer via appropriate interface logic .
  各种实体设备能够通过适当的接口逻辑电路对计算机传输（输入或输出）信息。
• Since the secondary winding is normally operated into a high-impedance circuit, the secondary current is quite small .
  因为次级绕组通常输入高阻抗的电路，因此次级电流很小。
