查询词典 arc-weld

A comparison between the numerical analysis by arc-length method and the test results shows good agreements in ultimate loads and moment- cubature relational curves.

进行了单调加载和反复加载截面的非线性分析，并与试验进行了对比，理论分析和试验结果吻合良好。

In this study, copper alloy adding Ti-Zr and Al-Zr was the target and made the cupper alloy ingots by vacuum arc remelter. After rolling and heat treatment, the two-inch round target was cut by wire electrical discharge machining. DC sputtering deposited cupper alloy thin films on silicon base materials and optical glasses to discuss the thin film microstructures、compositions、practical performances and optical characteristics.
