Some crack extension probably developed from the unfused section of the butt weld across the thickness of the stiffener during transport and erection . 有些裂纹可能在运输和安装过程中就从加劲肋对接焊未熔透处开始发展。
The refractory metals and refractory metal silicides that are used to augment or replace the polysilicon are generally deposited by physical vapor deposition processes . 用于增强和取代多晶硅的难熔金属和难熔金属硅化物通常是用物理蒸发沉积工艺沉积的。
Cell connectors and terminal post burning must be done in such a manner that there is complete fusion of the post strap top and the cover lead bushing with the connector ring or terminal post . 连接条和接线柱的焊接必须使极柱顶部和盖子的铅衬套与连接条环口或接线柱完全熔焊牢固。
