calibrate GRE

1.It is especially powerful for calibrating quarte-wave-plate and half-wave-plate, the metrical precision is less than 0.1%.

对于1/4波和半波量精度于0.1%。

2.The NRG Pyranometer is an excellent general purpose solar radiation sensor that is calibrated for the daylight spectrum.

NRG日照是质太阳辐射量，量直射和折射太阳辐射，从而得出总辐射量。输出一个低电流信号。

3.A reference material for calibrating and verifying the calorimeter of propellant explosion heat is composed of nitrocellulose(NC),nitroglycerine(NG),centralite and vaseline.

采用硝化棉、硝化甘油、中定剂和凡士林为火药爆热热量计检定用标准物质组成成分,通过生产工艺化制备出该标准物质。

4.California Instruments joins AMETEK as part of its Electronic Instruments Group (EIG) -- a provider in advanced monitoring, testing, calibrating, and display instruments.

加利福尼亚仪公司作为其电子企业集团（EIG）一部分加入AMETEK，该集团是先进监视、试、校准和显示仪提供商。

5.As a consequence of the drift of inclinometer's mechanicalness and electrical circuit during the long-dated observation,the lattice value of the inclinometer's record trunk must be calibrated termly.

在长期观过程中,仪机械部分和电路部分均会产生漂移,因此,仪记录曲线格值必须定期进行标定。
