电压线

Otherwise, the load components receive the same harmonically-rich voltages and the lines see the same currents as in a three-wire Y system.

以别的方式，负载成分调和地接到一样的-富有的电压和线见到那同一的涌流当做在一个三电线的 Y 系统中。

These voltages may be across just three wires, to form a three-wire, three-phase circuit.

这些电压，可在短短3线，形成三线，三相电路。

Steel towers,called pylons,serve to carry the insulators,with each conductor suspended from the bottom of a group or string of insulator units.

高电压，高线建设通常是用于悬挂式绝缘钢塔，要求塔，进行服务的绝缘体，每个售票员暂停底部的一组或一系列绝缘体单位。

Adopting multiplexing technique and making use of communication line between CSC and CS to achieve simultaneous transmission of ISDN signal and electric power. According to the variation of circuit equivalent resistance to design detection circuit, which can judge that the line is short circuit or open circuit and the commercial power is working normally or failure. When the reserve power supply is working, the system judges its operation status by voltage and current detection circuit. Making use of the characteristic of the gas discharge tube to achieve suspension system detection of power line touching. Transmitting information collected up to PC by RS485 for the purpose of centralized monitoring.

采用复用技术，利用基站控制器和基站间的通信线路实现ISDN信号和电力的共同传输；根据线路等效电阻的变化设计探测电路，来判断开路、短路、市电供电、市电停电等情况；在后备电源工作时，通过电压、电流采样电路判断电源的运行情况；利用气体放电管的特性实现悬浮系统动力线搭接的检测；采用RS-485通信方式将采集到的现场信息上传以实现集中监控。

If we assume that we can tolerate errors of no more than 0.5 LSB, this calculation tells us that in a 16-bit SYSTEM with 10 V FS we must KEEP the total error to less than 76 pV, which is approximately equal to the thermo- ELECTRIC voltage in a nichrome wirewound RESISTOR with copper/nickel leads having about 2℃ temperature difference between its ends.

假设电路的噪声必须小于0.5LSB，按照前面的计算，这意味着在10V量程的电路中必须将噪声控制在76uV以下，而这个电压大致与线绕电阻的两个引脚间温差2C时的热噪声相当。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
