Zhongguo shiyan zhenduanxue, 2012 小肠梗阻的原因很多,早期病因诊断对外科治疗具有重要的意义。腹内疝是指腹内脏器自其原来的位置,经过腹腔内一个正常或异常的孔道或裂隙脱位到一个异常的腔隙,小肠内疝是小肠梗阻的一个特殊类型,其多表现为发病急,疼痛较早较出现,较为剧烈,病情进展较快。老年患者反应慢,小肠内疝发生后症状往往不典型,常被误认为普通的粘连性肠梗阻 ...

Zhendong Ceshi yu Zhenduan针对振动作用下发电机绕组绝缘断裂损伤机理与偏心故障影响机制尚未明确的问题，提出考虑静态偏心故障的绕组绝缘损伤分析方法。首先，建立理论模型，对偏心前后的绕组电磁力与绝缘断裂情况进行解析；其次，构建有限元分析模型并进行电磁场分析，验证偏心前后的电磁力分布、幅值及频率变化；然后，进行结构场仿真，揭示绝缘应力分布与裂纹扩展情况；最后，通过实验来验证理论模型与有限元分析结果。结果表明：在正常情况下，各绕组所受电磁力基本相同；发生偏心故障后，气隙减小（增大）处绕组电磁力增大（减小 ...
