静电计

As such, it can be used for many measurements performed by a conventional DC multimeter.

静电计是一种高度精密的直流多用测量仪表。

Figure 1-18 shows the basic configuration of an alternative form of electrometer ohmmeter.

图1-18示出另一种形式的静电计欧姆计的基本电路结构。

The ohmmeter uses an internal current source and electrometer voltmeter to make the measurement.

欧姆计使用内部的电流源和静电计电压表来进行测量。

Therefore, it's prudent to measure the insulation resistance of the test fixtures and cables periodically with an electrometer ohmmeter to ensure their integrity.

因此谨慎的做法是定期地用静电计欧姆计来测量测试夹具和电缆的绝缘电阻，以保证其完整性。

The electrometer ohmmeter makes a two-wire resistance measurement at a specific test current, depending on the measurement range.

静电计欧姆计依据测量的量程，在规定的电流下，进行两线电阻测量。

To perform the test, connect an electrometer to the Faraday cup using a shielded cable.

为了进行测试，用屏蔽电缆将静电计和法拉第杯连接起来。

To measure the offset current, close a specific crosspoint and use an electrometer or SMU to measure the current with everything in place except the device under test.

为了测量偏移电流，请闭合特定的交叉点，并利用一个静电计或SMU来测量电流。在测量时，除被测装置外，所有的其它设备要连接完整。

The results show that the polymer determines the electricity conducting of coal filled polymer composites. The coal filled PP composites is an insulating material, and be independent of coal type, its direct current resistivity is above 10〓Ω·cm. The resistivity drops with the content of coal when using anthracite, but it is also above 10〓Ω·cm, and the surface modification of coal, especially alkylated, resumes the insulance of composites.

X射线衍射测试表明即使在高变质程度下煤中的石墨晶区含量仍较低，煤填充聚合物复合材料电性能主要由基体材料性能决定，通过动电容静电计对煤填充聚丙烯复合材料直流电导性研究表明，煤填充聚丙烯复合材料是绝缘材料，其绝缘电阻在10〓Ω·cm以上，在高含量情况下，仍能保持良好的绝缘性，而与煤种无关。

Electrometers can be very useful where electrode areas are very small and solution conductivities are very low.

当电极面积非常小而溶液的导电率非常低时，静电计是非常有用的。

Current integration and measurement of charge are electrometer coulomb- meter capabilities not found in multimeters.

电流积分和电荷测量是只有静电计才具有的功能，在数字多用表中找不到这样的功能。

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。
