查询词典 derived

The some basic methods in composite mechanics are introduced,and relative formulations are derived.Maximum stress criterion,Maximum strain criterion,Hill criterion and Cai-Wu criterion are showed.The solid model of level-stability-panel is built by CATIA software,its finite element model by PATRAN/NASTRAN software.Through finite element analysis,the stresses and displacements of level-stability-panel are obtained.In order to analyze the strength of asingle part of level-stability-panel,the software CLOP is developed.The process of taking the data from NASTRAN's results and importing them to CLOP is showed.The strength of back wall of lev el-stability-panel is calculated by CLOP.

The molecular weight dependence of the distribfition of polymer molecules between the coacervate and the dilute phases on the phase separation of polymethylmethacrylate-acetone-methanol system has been proved to follow the relation first derived by Flory for binary systems: f"_j/f′_j = Qe~_j where f"_j and f′_j are the weight fractions of the polymer molecules of molecular weight M_j in the coacervate and in the dilute phases respectively, while Q and σ are parameters.

1。聚甲基丙烯酸甲酯-丙酮-甲醇体系的两次分相实验用θ-溶剂中的沉降速度法测定分相前试样和浓相的分子量分布曲线，得到高分子在浓稀相重量分配的分子量依赖关系 f_j=Qe~证实Flory的溶度函数形式与实际相符，并适用于三元体系的相分离，但Q值与两相体积比R值并不相同。 2。再分级使级分的分子量分布宽度随再分级次数的增加而减小，通常认为到第三次再分级其效果已不显著并不确实。
