It is very difficult to measure the passing current in insulators.

在绝缘体中测定通过的电流是很困难的。

This current is known as the input offset current, and it is caused by bias currents of active devices as well as by leakage currents through insulators within the INSTRUMENT .

这个电流就是输入失调电流，它可能是由有源设备的偏置电流引起的，也可能是由仪器内的绝缘体泄漏电流引起的。

Currents can be internally generated, as in the case of instrument input offset current, or they can come from external sources such as insulators and cables.

这种电流可以在内部产生，如仪器的输入偏置电流；也可以从外部而来，如来自绝缘子和电缆。

This current is known as the input offset current, and it's caused by bias currents of active devices as well as by leakage currents through insulators within the instrument.

这种电流称为输入偏置电流，是由有源器件的偏置电流以及流过仪器内部的绝缘子的泄漏电流所引起的。

Currents can be internally generated, as in the case of INSTRUMENT input offset current, or they can come from external sources such as insulators and CABLES .

附加电流既可以从内部产生，如仪器输入失调电流的情况下；也可从外部产生，如来自诸如绝缘体和电缆的外部"源"。

A method for leakage current detection of insulators based on LabVIEW is described.

描述了一种基于LabVIEW的绝缘子漏电流检测方法。

Semiconductors are materials that lie midway between insulators and conductors in their ability to pass an electric current.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
