简介：AIMTo用光连贯断层摄影术(10月)并且到在奔流外科以后在糖尿病的眼睛估计斑点的量的变化估计开发的发生或有斑点的浮肿变得更坏(我)在糖尿病的眼睛与或没有先存在ME.METHODSIn这未来的、观察研究，经历了奔流外科的60个糖尿病的病人的92只眼睛在外科前被评估并且1，在用10月有斑点的厚度的外科以后的3mo在九有斑点的子字段与10月被测量定义b另外，开发的发生或我变得更坏在糖尿病的眼睛被分析与或没有先存在，ME.RESULTSThe中央子字段平均数厚度增加了21.0µ；m和25.5µ；在1点的m，3mo后续，分别地(P<；0.01)。内部戒指和外部戒指的平均厚度增加了14.2µ；m和9.5µ；在1mo的m，18.2µ；m和12.9µ；在3mo的m。中央包含我在3mo在12只眼睛发展了，包括4与先存在与先存在看中央包含和8只眼睛非中央包含了我。先存在的糖尿病的有斑点的浮肿(DME)显著地与中央包含被联系我开发(P<；0.001).CONCLUSIONA尽管增加是温和的，统计上重要的增加能在中央子字段以及perifoveal和parafoveal部门被检测。并且有在奔流外科以前的外科手术前的DME的眼睛在为开发中央包含的更高的风险我。

简介：剩余在SUS304不锈钢的墙中强调圆柱的绘画杯被裂口戒指测试评估，并且踩的影响死剩余压力上的参数被调查。裂口戒指测试的一个新理论模型被开发在一枚戒指评估剩余压力，它被验证由有ABAQUS代码并且由nanoindentation测试的数字模拟合理、可靠。七组裂口戒指测试被完成，并且剩余压力根据理论模型的意见是计算的。裂口戒指测试结果证明环绕的剩余在SUS304不锈钢的墙中强调圆柱的绘画杯很大并且没随着变化不同死角落半径。环绕的剩余压力首先随画punchdie清理的增加增加了，当清理增加了时，当时是几乎未改变的比空白的厚度大1?公里。因此，一个更小的清理被建议被选在拉杯的SUS304不锈钢的墙中减少剩余压力。
