查询词典 beryllium

From Beryllium Bronze Magnetic Materials zero, therefore, also known as bronze tools Antimagnetic tool operating in the field of environmental security.

因铍青铜材料磁性为零，所以铍青铜工具又称防磁工具，可在磁场环境安全作业。

The anticlastic curvature caused by bending is 1700 times as long as the sagittal curvature, and the incident angle error is only 2.2 μrad. The Von Mize stress on the bender is about 806 MPa. When Beryllium-Cu is selected as the material of the bender, the linear relationship between the curvature of crystal in 0.57~1.72 m and the driving forces in 8~2.67 N is obtained.

优化后晶体因压弯产生的鞍形曲率半径约为弧矢曲率半径的1700倍，造成的人射角误差为2.2μrad；压弯装置上的最大平均应力约为800MPa，并由此确定了以铍青铜作为压弯机构的材料，晶体的曲率半径为0.57~1.72m和驱动力为8~2.67N时的线性关系。

I will not give up and will not call you any more at the same time.

我不会放弃，同时我也不会在给你打电话了。
