电压

• The overvoltage varies inversely with the current density to some extent .
  超电压在某种程度上随电流密度成反比地变化。
• However, high breakdown voltages necessarily need high-resistivity material .
  但是，高的击穿电压必然要求采用高阻材料来制作。
• Lines within the field along which the voltage is constant are called equipotential .
  在电场中电压根等的那些曲线称为等位线。
• It enables the rotor with constant speed for maintaining steady output voltage .
  它使转子能以恒定速度转动，保持输出电压稳定。
• The "mark" or "space" condition is represented by the voltage between two wires .
  “传号”或“空号”条件是由两条线之间的电压来表示的。
• The demodulator receives its reference voltage from the signal-generator voltage supply .
  解调器的参考电压由电信号发生器电压电源供给。
• The transient voltage is read at closely spaced intervals after termination of the current .
  在电流中断后的一系列短区间上读出瞬变电压。
• The decaying voltages can be measured for a time after the current is switched off .
  在电流断开后的一段时间里，可以测量到逐渐下降的电压。
• It follows that with the voltage on, the losses are high, so oscillation is prevented .
  由此可见，加上电压后，损耗增大，因此振荡受到阻止。
• Ammeter, voltmeter, bridge and similar common methods are typical equipment types .
  电流表、电压表、电桥以及类似的常见仪器都属于常用的设备。
