The well-known empirical e-lgσ' relation is introduced into the study on one-dimensional nonlinear consolidation of one-layered soil under cyclic loadings. The corresponding consolidation equation is established with the assumptions that the decrease in permeability of soil is proportional to the decrease in compressibility during the consolidation process and that the distribution of initial effective pressure does not vary with depth.

将孔隙比e与有效应力σ'关系引入循环荷载作用下单层地基的一维非线性固结问题的研究之中，通过假定土体中的初始有效应力沿深度均匀分布和固结过程中上体渗透性的降低与压缩性的减小成正比，建立了低频循环荷载作用下单层地基的一维非线性固结问题的固结方程。

However, the way of generating new individuals is different. TE generates new individuals in a Nelder-Mead way, while the simplices used in TE is 1 or 2 dimensional.

但TE产生新个体的方式不同，它以Nelder-Mead方式产生新个体，同时TE仅使用1维或2维单纯形。

In the meantime, the difference between a direct integration method and a modality superposition method in the nonlinear solution of large sized shaftings was also investigated. It can be shown that the use of a nonlinear method for solving the kinetics response of a higher dimensional rotor bearing system is both essential and feasible. With regard to the nonlinear kinetics problems of a rotor system the direct integration method is more effective than the modality superposition method. steam turbine, rotor, dynamics, nonlinearity

国内外先后采用非线性油膜力的数值积分方法对转子轴承系统的非线性动力学行为进行了一定研究，但主要集中在简单转子—轴承系统的研究上，在分析上主要采用的是简单离散方法，转子多被简化为刚性转子和Jeffcott转子模型，只能对简单转子—轴承系统的非线性动力学行为进行定性的分析，而对于象汽轮机组轴系这样的高
