简介:一个一阶的扭转理论基于Vlasov理论被开发了调查开的薄墙的横梁的制止的扭转。生气的节的全部的旋转被划分成免费变弯旋转并且一制止砍旋转。在一阶的扭转理论,圣韦南特转矩仅仅与免费变弯旋转有关,圣韦南特转矩的表示被使用一个半逆方法导出。在变弯的转矩之间的关系并且制止砍旋转被使用一个精力方法建立。扭转砍系数然后被获得。根据扭转平衡,管理制止的扭转的微分方程被导出,相应起始的方法被给解决方程。在全部的旋转和免费变弯旋转之间的关系被获得。一个参数,与生气的节和横梁长度的僵硬性质被联系,被介绍决定条件,圣韦南特常数在下面是可以忽略的。因而,一个简化理论被导出。数字例子被说明验证当前的途径,当前的理论的结果与一些另外的可得到的方法的那些相比。比较的结果证明当前的理论提供更精确的结果。在一根塑造隧道的伸臂横梁的例子,简化理论的适用性被参数学习决定。

简介:AbstractIntroduction:Eruptive cutaneous collagenoma is non familial connective tissue nevi of unknown etiology presented with an abrupt onset. To date, the literatures on eruptive cutaneous collagenoma are extremely rare in china.Here, we report two women with eruptive cutaneous collagenoma.Case present:Two women presented with multiple asymptomatic, skin-colored papules and nodules on the trunk and extremities with no systemic involvement. Histopathology revealed dense, coarse collagen fibers by hematoxylin-esoin stain and decreased, fragmented elastic fibers by Elastic stain compared with the normal skin. Basing on these findings, the diagnosis of eruptive cutaneous collagenoma was made. No specific treatment was given.Discussion:Eruptive cutaneous collagenoma is a very rare dermatosis that is often misdiagnosed as other connective tissue nevi. The pathogenesis is unclear, and also no efficient treatment is available. It is usually diagnosed based on clinical and histopathological findings.Conclusion:The present cases are relatively rare type of eruptive cutaneous collagenoma that provide more experience for clinician, and may be helpful for them to make correct diagnosis for suspicious cases.
