静电计

Refer to the instrument's instruction manual for information on a particular electrometer's internal damping feature.

关于特定静电计内部衰减电路的性能，请参阅该仪器的操作手册。

The unknown capacitance is connected in series with the electrometer input and the step voltage source.

将未知电容与静电计输入和步进电压源相串联。

Therefore, a voltmeter with high input resistance, such as an electrometer, is required.

所以需要使用具有高输入电阻的电压表，例如静电计。

Electrometer and nanovoltmeter characteristics differ, so the operational amplifier requirements for these two types of instruments are also somewhat different.

静电计和纳伏表的特性不同，所以这两种仪器对运算放大器的要求也有所不同。

The resistors are current limiting resistors used to protect the switches and electrometer from high current.

电阻器是电流限制电阻器，用来保护开关和静电计不受大电流的损害。

This can be checked by observing the analog output of the electrometer or picoammeter with an oscilloscope.

用示波器观察静电计或皮安计的模拟输出，可以对此进行检查。

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。

Enabling the guard effectively reduces the cable and switch capacitance, thereby improving the electrometer's response time.

采用保护可有效降低电缆和开关电容，从而改善静电计的响应时间。

The noise performance of the electrometer is analyzed in detail and conclude that the input current noise is main factor on noise of the electrometer.

对静电计放大器的噪声性能做了细致的分析，确定了输入电流噪声为放大器噪声的决定因素。

He first used a Nicholson doubler with his straw electrometer, next a Bennet gold leaf electroscope by itself, and finally a Bennet electroscope combined with his variable capacitance multiplier.

他首先使用了尼科尔森加倍装置和他的稻草静电计，其次使用水杨梅金箔验电器，和最后和他的可变容量的倍加器结合的一个水杨梅验电器。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
