| 1 | 铜添加对近共晶Al-Si-xCu合金的微观组织和硬度的影响(英文)显示文摘研究铜含量对Al-Si-xCu(x=2%,3%,4%and5%)合金的微观组织和硬度的影响。不同铜含量的铝合金经熔炼后于690°C铸造成湿砂模并固化,于500°C保温7h进行固溶处理后对样品进行水冷。随后于190°C进行时效处理,分别保温5,10和15h,研究时效时间对基体硬度的影响。采用差热分析法,在冷却速度30K/min下确定平衡相的转变温度,并研究铜含量对四元共晶合金的形成和α(Al)+Si熔点的影响。结果表明,随着铜含量的增加,发生析出硬化从而导致基体硬度增加,α(Al)+Si的熔点降低,共晶相的含量增加。当铜含量超过2%时,生成熔点为507°C的四元共晶相。 | MUZAFFER ZEREN ERDEM KARAKULAK SERAP GüMü | 2011 | Transactions of Nonferrous Metals Society of China2011，21，8： | 8 |
| 2 | Prevalence of microscopic colitis in patients with diarrhea of unknown etiology in Turkey显示文摘AIM: To investigate the prevalence and demography of microscopic colitis in patients with diarrhea of unknown etiology and normal colonoscopy in Turkey. METHODS: Between March, 1998 to July, 2005, 129 patients with chronic non-bloody diarrhea of unexplained etiology who had undergone full colonoscopy with no obvious abnormalities were included in the study. Two biopsies were obtained from all colonic segments and terminal ileum for diagnosis of microscopic colitis. On histopathologic examination, criteria for lymphocytic colitis (intraepithelial lymphocyte ≥ 20 per 100 intercryptal epithelial cells, change in surface epithelium, mononuclear infiltration of the lamina propria) and collagenous colitis (subepithelial collagen band thickness ≥ 10 μm) were explored. RESULTS: Lymphocytic colitis was diagnosed in 12 (9%) patients (Female/Male: 7/5, mean age: 45 year, range: 27-63) and collagenous colitis was diagnosed in only 3 (2.5%) patients (all female, mean age: 60 years, range: 54-65).CONCLUSION: Biopsy of Turkish patients with the diagnosis of chronic non-bloody diarrhea of unexplained etiology and normal colonoscopic findings will reveal microscopic colitis in approximately 10% of the patients. Lymphocytic colitis is 4 times more frequent than collagenous colitis in these patients. | Levent Erdem Sadιk Yιldιrιm Nihat Akbayιr Banu Yιlmaz Necati Yenice Orhan Sami Gültekin nder Peker | 2008 | World Journal of Gastroenterology2008，14，27： | 2 |
