| 1 | 焊接参数对搅拌摩擦焊接AA2219-T87材料韧性、洋葱圆环的断裂行为的影响(英文)显示文摘与熔焊相比,搅拌摩擦焊可以更好地保持材料的韧性和塑性,提高焊接的抗裂稳定性。本研究旨在提高焊接接头的延性和强度。刀具廓形在保持延性、分析金属流动行为和确定断裂起始点等方面起着重要作用。分析了洋葱圆环不同区域的微观结构,得出了洋葱圆环强度与金属流型的关系。结果表明,洋葱圆环强化了焊缝熔核。肩部和锥形螺纹型线刀具具有优异的力学性能。显微硬度数据表明,断口经过热影响区和热机械影响区等低硬度区。扫描电镜图像显示了细长的晶粒和韧窝,证实了断裂为韧性断裂。 | Dinesh KUMAR R S MUTHUKUMARAN Vincent XAVIER T VENKATESWARAN D SIVAKUMAR | 2019 | Journal of Central South University2019，26，9： | 2 |

| 3 | Laparoscopic esophagomyotomy for achalasia in children:Areview显示文摘Esophageal achalasia in children is rare but ultimately requires endoscopic or surgical treatment. Historically, Heller esophagomyotomy has been recommended as the treatment of choice. The refinement of minimally invasive techniques has shifted the trend of treatment toward laparoscopic Heller myotomy(LHM) in adults and children with achalasia. A review of the available literature on LHM performed in patients < 18 years of age was conducted. The pediatric LHM experience is limited to one multiinstitutional and several single-institutional retrospective studies. Available data suggest that LHM is safe and effective. There is a paucity of evidence on the need for and superiority of concurrent antireflux procedures. In addition, a more complete portrayal of complications and long-term(> 5 years) outcomes is needed. Due to the infrequency of achalasia in children, these characteristics are unlikely to be defined without collaboration between multiple pediatric surgery centers. The introduction of peroral endoscopic myotomy and single-incision techniques, continue the trend of innovative approaches that may eventually become the standard of care. | T Kumar Pandian Nimesh D Naik Aodhnait S Fahy Arman Arghami David R Farley Michael B Ishitani Christopher R Moir | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，2： | 2 |
