The sample quantiles are established from a pair of single spacing. Finally, a table of the variances and efficiencies of the estimator for 5≤n≤65 is provided and comparison is made with other linear estimators.展开更多

For clinical effectiveness, these garments are made in appropriate size for individual patient in order to provide an appropriate amount of skin-and-garment interface pressure on the patient.The seam area of pressure garments has marked impact on the comfort and durability of the pressure garments.Comments from the patients and occupational therapists have indicated that discomfort arose in the seam zone.Line marks appeared on the skin of patients under the seamed areas of pressure garments. This may be caused by uneven or Iocalised interface pressure at the seamed area. In this paper, the changes of interface pressure between the seamed and unseamed areas were investigated. The aim is to provide an understanding of the effect of seams on the interface pressure in order to assist the therapists and/or garment makers to choose an appropriate展开更多
本文的主题是分析DP600、TRIP700、H340LAD三种汽车用薄板钢的试验结果。出于比较的目的，本文还引入了在LPMM做的ES（DC05）软钢的试验结果。常温下以相对较宽范围的应变速率（从～3．0·10^-4／s至～10^3／s）进行拉伸试验。因为...本文的主题是分析DP600、TRIP700、H340LAD三种汽车用薄板钢的试验结果。出于比较的目的，本文还引入了在LPMM做的ES（DC05）软钢的试验结果。常温下以相对较宽范围的应变速率（从～3．0·10^-4／s至～10^3／s）进行拉伸试验。因为在高或低应变速率下采用了两个不同的试样尺寸，所以进行了详细的数值分析，以评估在不同的应变速率下试样尺寸对最终真实应力与真实应变特性之间关系的影响。应用了由Rusinek and Klepaczko开发的相对较新的（σ^-，c^-p，c^△p，T）=0形式的本构关系。这个力学状态方程（MES）形式的本构关系又称为RK关系，其主要优点是引入了应变硬化指数的速率和温度敏感性n（c^-p，T），与其他本构公式相比这是一个非常重要的改进。根据Rusinek and Klepaczko的方法，应用了一个特殊的程序，来确定三钢种的材料常数。结果与试验数据拟合良好。展开更多
