研究了触变铸造、触变铸造+T6人工时效以及挤压态AA7075合金的拉伸断裂行为。采用光学显微镜和扫描电子显微镜研究了合金的显微组织和断口形貌。结果表明,挤压态和触变铸造+T6人工时效的合金具有比触变铸造合金更优越的力学性能。延长固溶时间后T6人工时效可使触变铸造AA7075合金的拉伸性能大大提高。挤压态和触变铸造+T6人工时效合金的拉伸性能相近。触变铸造合金中存在明显的微裂纹,其断裂形式为晶间脆断。而挤压态和触变铸造+T6合金的断裂形式为韧性断裂。对于触变铸造合金,破坏始于共晶基体界面之间,并在晶间扩展。微孔缩聚是触变铸造+T6人工时效合金的主要断裂模式。而微孔形核于基体与多元共晶组织的界面。

The airborne pollen grains of Afyon have been studied for a two_year period (1999-2000) with a Durham sampler. A total of 14 367 pollen grains belonging to 40 taxa have been identified and recorded with some unidentified ones. Of them, 6 732 were identified in 1999 and 7 635 in 2000. Of the total pollen grains, 69.67% were arboreal, 26.64% non_arboreal and 3.68 % unidentified. The majority of the investigated pollen grains were from Pinus, Gramineae, Cupressaceae, Platanus , Chenopodiaceae/Amaranthaceae, Quercus, Ailanthus, Moraceae, Juglans , Salix, Cedrus and Rosaceae. The highest level of pollen grains was in May.

Results of the open surgery after endoscopic basket impaction during ERCP procedure

引用

World Journal of Gastrointestinal Surgery 2015年第2期7卷 15-20页

作者： Sezgin Yilmaz Ogun Ersen Taner Ozkececi kadir S Turel Serdar Kokulu Emre Kacar Murat Akici Murat Cilekar Ozgur Kavak Yuksel Arikan Department of General Surgery Kocatepe University Department of General Surgery State Hospital Department of Anaesthesiology Kocatepe University Department of Radiology Kocatepe University

AIM:To report the results of open surgery for patients with basket impaction during endoscopic retrograde cholangiopancreatography(ERCP) procedure.METHODS: Basket impaction of either classical Dormia basket or mechanical lithotripter basket with an entrapped stone occurred in six patients.These patients were immediately operated for removal of stone(s) and impacted basket.The postoperative course,length of hospital stay,diameter of the stone,complication and the surgical procedure of the patients were reported retrospectively.RESULTS: Six patients(M/F,0/6) were operated due to impacted basket during ERCP procedure.The mean age of the patients was 64.33 ± 14.41 years.In all cases the surgery was performed immediately after the failed ERCP procedure by making a rightsubcostal incision.The baskets containing the stone were removed through longitudinal choledochotomy with the stone.The choledochotomy incisions were closed by primary closure in four patients and T tube placement in two patients.All patients were also performed cholecystectomy additionally since they had cholelithiasis.In patients with T-tube placement it was removed on the 13 th day after a normal T-tube cholangiogram.The patients remained stable at postoperative period and discharged without any complication at median 7 d.CONCLUSION: Open surgical procedures can be applied in patients with basket impaction during ERCP procedure in selected cases.
