loss in grade的意思|示意

The surface scattering loss (SSL) in the optical loss of laser reflectors is the main, sometimes fatal influence on the performance and test of high-grade precision and advance instruments.

在激光反射镜的光学损耗里，表面散射损耗(SSL)对高精密的激光仪器性能和实验影响尤甚，有时是致命的。

In order to obtain the stability Of ore grade, two aspect works we should do: (1) Enhancing the management in the loss mine and the increasing rock;

确保出矿品位的稳定主要有两方面的工作：一是加强损失贫化管理；

By analyzing the relationship between speed loss, speed discount in different gradient and grade length, the paper also brings forward the maximum longitudinal gradient and grade length limit.

通过速度折减量与坡长之间的关系曲线，提出基于运行速度差和满足公路服务水平要求的各级公路最大纵坡坡度与坡长限制值。

Low power coefficient may result in loss increased, efficiency decreased and the harmonic makes the power quality down-grade when a submerged arc furnace was operating.

电石炉运行时，很低的功率因数使得损耗增加效率降低，产生的谐波使电网电能质量降低。
