1O形密封圈的有限元力学分析显示文摘采用大型有限元分析程序 MARC/ Mentat32 0对 O形密封圈在“安装”状态和密封流体介质作用下的力学性能进行了分析 ,研究了造成密封圈撕裂损坏及材料松弛的当量 Cauchy应力峰值大小及位置随密封流体介质作用的变化情况 ,以及轴和密封接触面间的接触压力及剪应力分布状态。为重要场合下 O形密封圈的正确选用提供了一种方法。陈国定 Haiser H Haas W Lechner G 2000机械科学与技术2000,19,5:115
2阶梯组合密封件的力学性能研究显示文摘采用大型有限元分析软件 MARC/ Mentat32 0 ,分析了阶梯组合密封件 (阶梯形密封 +O形密封圈 )截面上的当量 Von Mises应力分布 ,使用三种不同硬度 O形密封圈的阶梯组合密封件在不同工况下的径向力、密封接触区宽度及摩擦功耗。所获得的计算结果对于阶梯组合密封件的设计及使用都是非常有意义的。陈国定 Haiser H Haas W Lechner G 2000机械科学与技术2000,19,6:15
3密封系统性能的表面粗糙效应试验研究显示文摘分析了密封系统中硬对偶件表面粗糙特性对密封系统工作性能的影响,揭示了在相对运动密封零件表面间摩擦学过程中出现的微观曲路密封效应和微观跑合效应,为通过控制密封系统中硬对偶件表面加工工艺以形成优秀的表面形貌,来提高密封系统的工作性能提供了新的思路和概念。陈国定 Haiser H Haas W Lechner G 2000机械工程学报2000,36,6:3
4Differential diagnosis in patients with suspected bile acid synthesis defects显示文摘AIM: To investigate the clinical presentations associated with bile acid synthesis defects and to describe identification of individual disorders and diagnostic pitfalls. METHODS: We describe semiquantitative determination of 16 urinary bile acid metabolites by electrospray ionization-tandem mass spectrometry. Sample preparation was performed by solid-phase extraction. The total analysis time was 2 min per sample. We determined bile acid metabolites in 363 patients with suspected defects in bile acid metabolism. RESULTS: Abnormal bile acid metabolites were found in 36 patients. Two patients had bile acid synthesis defects but presented with atypical presentations. In 2 other patients who were later shown to be affected by biliary atresia and cystic fibrosis the profile of bile acid metabolites was initially suggestive of a bile acid synthesis defect. Three adult patients suffered from cerebrotendinous xanthomatosis. Nineteen patients had peroxisomal disorders, and 10 patients had cholestatic hepatopathy of other cause. CONCLUSION: Screening for urinary cholanoids should be done in every infant with cholestatic hepatopathy as well as in children with progressive neurological disease to provide specific therapy.Dorothea Haas Hongying Gan-Schreier Claus-Dieter Langhans Tilman Rohrer Guido Engelmann Maura Heverin David W Russell Peter T Clayton Georg F Hoffmann Jürgen G Okun 2012World Journal of Gastroenterology2012,18,10:2
