静电计

Electrometer voltmeters and voltage measurements on high resistance sources were described in Sections 1 and 2 respectively.

第一章和第二章已经分别对静电计电压表和高阻源电压测量的问题进行了介绍。

An electrometer makes an ideal coulombmeter because it has very low input offset current and high input resistance.

静电计是一个理想的库仑计，因为它具有非常低的输入偏置电流和很高的输入电阻。

The following paragraphs examine considerations that apply to all types of electrometer and SMU measurements on high resistance sources.

以下各段考察所有类型的静电计和SMU在测量高阻源时要考虑的问题。

The damping circuit may already be built into the electrometer or may be an external circuit.

衰减电路可以装在静电计的内部，也可以是一个外部电路。

Input resistance is usually similar to that of a DMM and is much lower than that of an electrometer.

输入电阻类似于数字多用表，而远低于静电计。

6 General Electrometer Considerations: A discussion of techniques and error sources that affect high impedance measurements in general.

2.6 一般静电计要考虑的问题：一般性地讨论影响高阻测量的技术和误差来源。

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 coulombs function of an electrometer can be used with a step voltage source to measure capacitance.

可以使用静电计的库仑功能和步进电压源来测量电容。

It can be readily measured, however, with an electrometer by using the technique described in Section VI-B.

它可以用静电计轻而易举地测定，其使用方法如第六节B所述。

As shown in Figure 2-40, this will cause a current to flow through the low to ground capacitance of the electrometer.

如图2-40所示，这将会引起电流流过静电计的低端到地的电容。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
