简介:AIMTo在划分的类型2糖尿病的patients.METHODSWe估计在choroidal厚度(CT)和糖尿病的retinopathy(医生)的早阶段之间的关联83个糖尿病的病人(51-80岁;50女性)进非糖尿病的retinopathy,组(NDR)和温和/中等的nonproliferative糖尿病患者retinopathy(NPDR)组织,并且把他们与26个非糖尿病的控制题目作比较(51-78岁;16女性)。Subfovealchoroidal厚度(SFCT)和parafovealchoroidal厚度(PFCT)用提高的深度成像被测量光谱域的光连贯断层摄影术(EDI10月)。眼睛的健康地位,疾病持续时间,身体团索引,和血红素A1c(HbA1c)是NDR,NPDR,和控制组的recorded.RESULTSThe平均数年龄68.0是戠牥晥?景吗?

简介:一个向轴的方向的大偏转有一张矩形的剖面图的可扩展的弄弯的横梁被调查。有弹性的横梁被假定满足Euler-Bernoulli假定并且用Ludwick类型材料做的。通过相当简化的集成,横梁的轴的紧张和弯曲在含蓄的明确的表达被介绍。包含的管理方程几何并且弄弯的横梁的材料非线性被射击方法导出并且解决。当横梁的起始的弯曲是零时,弄弯的横梁被堕落进一根直横梁,并且现在的模型获得的预言的结果与在开的文学的那些一致。数字例子进一步为弄弯的伸臂被给并且简单地支持在延伸之间的横梁,和couplings并且弯曲被作出对有利的裁决弄弯的横梁。
