英汉例句

• The voltage across RL1 is the picoammeter voltage burden, normally less than one millivolt, so the resulting current will be quite small.

  RL1上的电压为皮安计的输入端压降，通常小于1mV，所以产生的电流是相当小的。

• With this connection method, the picoammeter reads a negative current.

  采用这种连接方法时，皮安计读出的电流为负值。

• In most cases, an ammeter or picoammeter is used to measure current.

  多数情况下，安培计或皮安计是用于测量电流的。

• To make the measurement, a constant voltage is applied for a predefined period, usually 60 seconds, and the resulting current is measured with a picoammeter or electrometer.

  为了进行测量，在预定的时间(通常为60秒钟)内，给样品施加恒定的电压。然后，用皮安计或静电计测量产生的电流。

• Since the voltage burden of the electrometer ammeter or picoammeter is less than 1mV, the diodes won't conduct.

  由于静电计、安培计或皮安计的输入端压降小于1mV，这两个二极管不会导通。

• A picoammeter is an ammeter built along the lines of the ammeter function of an electrometer.

  皮安表是安培表的一个门类，其实质上是静电计中安培表功能的延续。

• Note that when none of the channels on the Model 7158 card are energized, terminals 2 and 4 are connected to the LO of the picoammeter (pA), which electrically is the guard terminal.

  注意，当7158型开关卡上没有通道被激励时，端子2和4是被连接到皮安计（pA）的LO端子的，它在电气上为保护端子。

• When compared with an electrometer, a picoammeter has a similar low voltage burden, similar or faster speed, less sensitivity, and a lower price.

  与静电计相比，皮安表具有类似的低输入端压降，相同或稍快的测量速率，较低的电流灵敏度和低廉的价格。

• Ir measurements often involve multiple conductors, so a switching system is often required to switch the picoammeter and the source to all the conductors in the test circuit.

  由于IR测量往往涉及到多芯导线，所以通常需要一套切换系统来将皮安计和源切换至测试电路中的所有导线。

• Usually, this method requires two instruments: a voltage source and a picoammeter or electrometer.

  通常，这种方法需要使用两台仪器：一台电压源和一台皮安计或静电计。

• The picoammeter reads the current at the last dynode, which is equal to the anode current minus the current flowing to the previous dynode.

  皮安计在最后一个倍增管电极处读取电流，此电流等于阳极电流减去流过前一个倍增管电极的电流。

• The measured current is usually quite small, so a picoammeter or electrometer is often required to make the measurement.

  测得的电流通常非常小，因此往往需要使用皮安计或静电计进行测量。

• Applications such as measuring light with a photomultiplier tube generally require the use of a picoammeter due to the low current levels involved.

  由于要测量的电流非常弱，所以用光电倍增管测量光的应用工作通常需要使用皮安计。
