您要查找的是不是：
- double j groove weld 双j形槽焊
- 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。
- Ureter catheterization,double J tube insertion under cystoscope and operation should be the main measure... 膀胱镜下输尿管插管,置入双J管内支架引流及手术是解除梗阻的主要方法。
- Objective To explore the new methods of putting in and withdrowing double J stent without cystoscopy. 目的探讨不用膀胱镜便可取出输尿管内支架管（双J管）的方法。
- Objective To explore the applied value and nursing of double J tube in operation on kidney and ureter. 摘要目的探讨双J管在肾输尿管手术中的应用价值及护理。
- Objective To summarize the causes of failed drainage of double J ureteral stents following ureteroscopy. 目的总结输尿管镜手术后应用双J管引流无效的原因。
- Methods During the operation on kidney and proximal end of ureter,the double J stent was connected with nephostomic tube. 方法行肾及输尿管上端手术时，将双J管与肾造瘘管用丝线连接，术后将两者一并拔出。
- Methods:118 patients with stone in ureter were treated with the above-mentioned lithotriptor routine indwelling double J tube. 方法:应用输尿管镜气压弹道碎石技术治疗输尿管结石118例,常规放置双J管。
- 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。
- So we have reasons to believe that double J ureteral catheter in the management of rectal bladder with a terminal colostomy should be spreaded. 结论：在直肠膀胱-乙状结肠腹壁造口术中，使用双J管作支架管可减轻住院期间的护理工作，缩短住院时间，减少住院费用及并发症，有推广应用价值。
- With ureteroscopy and a new double J ureteral stent replaced, there were no complications including perforation, vid and avulsion of ureter, infection. 结果采用输尿管镜下碎石术处理结石，同时更换双J管，无输尿管穿孔，假道，输尿管撕脱及泌尿系感染等并发症。
- Objective To explore the clini cal effect of double J catheter internal drainage used in pediatric Anderson-Hyn es pyeloplasty. 目的探讨双J管内引流在小儿离断性肾盂成形术中的应用效果。
- Objective To explore the clinical effect of double J tubes in urinary tract disease and the function of methylene blue(MB) in tubing operation. 目的探讨双J管(双J输尿管支架管)在泌尿系疾病治疗中的应用效果以及美蓝在置放术中的作用。
- 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。
- Objective: To evaluate clinical use of double J tube as an endo-sent in the Swiss lithoclast pneumatic lithotriptor in the endoscopic management of urinary calculi. 目的:探讨双J管在输尿管镜气压弹道碎石术中作内引流的临床疗效。
- Objective: The aim of this study was to investigate the merits of double J ureteral catheter in the management of rectal bladder with a terminal colostomy. 摘要目的：探讨双J管内引流在直肠膀胱-乙状结肠腹壁造口术中的应用价值。
- Objective:Research in the method of lay aside of Double J tube in the operation of Upper Urethra and prevention and cure of adaptive and syndrome symptom. 目的探讨双J管在上尿路手术中的置管方法，适应症及并发症的防治。
