The second part is discusses the design of the digital megohm meter based on single chip processor in the aspects of both hardware and software.

其次，基于低压配电网绝缘检测的实际需求，本课题研制的一种基于单片机的数字兆欧表，论文从软硬件两方面对其工作原理和性能作了详细的说明。

Two types of high megohm resistors are widely used: carbon-film and metal-oxide.

广泛使用的高兆欧电阻器有两种：碳膜电阻器和金属氧化物电阻器。

Or more are often referred to as high megohm resistors.

高兆欧电阻器使这些元件成为不寻常的器件。

Insulated electric resistance rates of leads should not less than 1 megohm.

导线间，导线对地绝缘电阻值不能低于 1 兆欧。

Especially the infrared thermometer, coating thickness, megohm table and other equipment diagnostics and nondestructive testing equipment in the industry application, we have a wealth of experience!

尤其是红外测温仪、涂层测厚仪、兆欧表等设备诊断仪器和无损检测仪器在行业的应用上我们有丰富的经验！

Where the ohm is too small a unit, we may employ the kilo-ohm and the megohm.

如果欧姆这个单位太小，则可用千欧和兆欧

First should measure all parts of insulated electric resistance before install it, and the motor insulated electric resistance should not less than 0.5 megohm.

3.5.3.3 安装前应首先摇测各部分对地绝缘电阻，电动机的绝缘电阻值不能低于 0.5 兆欧。

When compared with conventional resistors, carbon-film high megohm resistors are noisy, unstable, have high temperature coefficients, display high voltage coefficients, and are very fragile.

与普通电阻器相比，碳膜高兆欧电阻器噪声大、不稳定、温度系数高、电压系数大、并且非常脆。

Standard precision resistors produced using EVANOHM alloy R display a maximum drift of 5 ppm per year for 15 years (for resistance from 1 ohm to 1 megohm); secondary standards display drifts from ± 6 to ±23 ppm per year over a 14 year period.

使用 EVANOHM alloy R 材料制造的标准精密电阻器在15年里都具有不超过5ppm/年的流失率（电阻从1欧到1兆欧）；二级电阻器在14年内也保有± 6至±23 ppm/年的流失率。

Independently tested, LXT PVC provides superior resistance to regular PVC for leaching of anion, cation, and numerous trace metals when subjected to 18.2 megohm deionized water while maintaining ease of installation.

经过第三方独立测试，对于19.2兆欧姆去离子水，LXT PVC对于阴离子、阳离子和许多痕量金属的滤去具有极高的耐抗性，同时还保持安装的简便性。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
