您要查找的是不是：
- The second crack is a crack originating at the groove weld toe of the column flange-girder flange connection. 第二种是产生于立柱翼缘与主梁翼缘连接处的坡口焊缝焊趾处的裂纹。
- These attachments were considered secondary components, so no weld quality control has been imposed on the groove weld splice. 这些附连件被看作是次要的部件，所以在这种坡口焊接中没有进行焊接质量控制。
- The effective weld length for any groove weld, perpendicular or skewed to the direction of stress, shall be the width of the part joined. 对于任何开槽焊接，有效的焊接长度就是零件结合的宽度，且要垂直或倾斜于压力方向。
- The main case shifts by hand , distance control. Double H shift mode. The auxiliary case shifts automatically by compressed air. 主变速器为手动换档远程操纵，双H式换档方式，副变速器由压缩空气自动换档。
- The main case shift by hand, distance control or direct control. Double H shift mode. The auxiliary case shift automatically by compressed air. 主变速器为手动换档，可远程操纵或直接操纵，双H式换档方式，副变速器由压缩空气自动换档。
- The main case shifts by hand, distance control or direct control, double H shift mode. The auxiliary case shifts automatically by compressed air. 主变速器为手动换档，可远程操纵或直接操纵，双H式换档方式，副变速器由压缩空气自动换档。
- The main case shifts by hand (the servo shift could be chosen), distance control or direct control. Double H shift mode. The auxiliary case shifts automatically by compressed air. 主变速器为手动换档（可选装助力换档），远程操纵或直接操纵，双H式换档方式，副变速器由压缩空气自动换档。
- Hand distance control for main case, double H shift mode. Automatically shift by compressed air for auxiliary case. The differential locks by the compressed air in cylinder pushing joint sleeve. 主变速器为手动换档远程操纵，双H式换档方式，副变速器由压缩空气自动换档。差速锁的锁止是通过气缸压缩空气推动接合套实现。
- Often lack of fusion adjacent to the girder web in the transverse groove welds led to the cracking. 在靠近主梁腹板的横向坡口焊缝处常常出现未熔透而导致裂纹。
- Cracks have been found in the flange and web splices at groove welds in at least four bridges. 至少在四座桥梁的翼缘板和腹板拼接坡口焊缝中发现了裂纹。
- A large number of these cracks occurred because the groove welded component was considered a secondary member or attachment. 发生这许多裂纹是因为把这些坡口焊接部件作为次要构件或附件考虑。
- The paper introduces single "U" groove welding procedure for stainless steel inner cylinder of multilayer high pressure vessel,opening up a new method for welding clading stainless steel vessel. 要详细介绍了内商为不锈钢的多层高压容器外U形坡口的单面焊接工艺，从而为不锈钢复合容器的焊接开辟了一条新途径。

- I do not realize it is a double feature. 我原先不知道这是双片连映。
- Double agents live in a perpetual state of fear. 两面派永远过着提心吊胆的生活。
- I want a double room with a view. 我要一间能看到风景的双人房间。
- He was so fat that he had a double chin. 他胖得有双下巴了。
- The carpet is too thick to double up. 这地毯太厚没法折叠。
