假定上

The first process is to optimize the geometric parameters of the press, on the assumption that the servomotor rotates at a constant angular velocity equal to that of the constant velocity motor. The second process is to optimize the displacement trajectory of the servomotor based on the results of the first process while keeping the geometric parameter unchangeable.

然后，建立了混合驱动压力机的优化设计模型，并将优化分为两步：第一步，假定伺服电机角速度与常规电机相同的条件下，优化设计出压力机的尺寸参数；第二步，在第一步优化结果的基础上，使机构的尺寸参数不变，优化设计伺服输入运动规律。

Secondly, by the P-L estimation of survivor function, this paper proposed the regression models of polynomial cumulative hazard function distribution models, respectively in the case of complete date and random right censoring date; meanwhile generalized least squares estimations of unknown parameters were proposed respectively using two steps algorithm and principal component analysis algorithm.

与已有的关于多项式危险函数模型的研究成果相比，首先本文在统计模型的构造上充分考虑了累积危险函数乘积限估计量的非独立性，给出了协方差矩阵的估计；其次在模型检验方面，本文利用非参数回归分析方法，充分利用了数据本身的信息，减少了对回归关系假定的主观因素，因而分析结果更为可靠。

It seems, however, to be assumed in the American arguments on the subject that, if we allow Slavery to have been a primitive Family institution, the acknowledgment is pregnant with an admission of the moral defensibility of Negro-servitude at the present moment.

但在美国的论点中似乎有着这样的一个假定，即如果我们承认"奴隶制"曾经是一个原始的"家族"制度，这个确认实在就是意味着承认现在"黑奴制度"在道德上是有可以辩护的根据的。

Based on dynamic equilibrium equations of three-dimensional elasticity, a state equation was established for orthotropic foundation plates using double Fourier series, in which no assumption about stress or displacement modes was made. Analytical solutions and frequency equations of unified formulas were presented for thin and thick laminated foundation plates.
