本文运用数值模拟方法—快速拉格朗日法对滑坡进行了详细的分析。

In terms of continuum mechanics and nonequilibrium irreversible thermodynamics theories, compressible Leonov constitutive model is derived to describe large recoverable elastic strain development in non-isothermal flow of compressible viscoelastic melts. It is tempting to specify the model and then compare it to basic rheological tests in the hope that such a model will yield a good description of the nonlinear viscoelasticity of polymer melts.

注射成型是聚合物的主要成型加工方法之一，成型过程中聚合物要经历熔体流动和固化等非等温、非平衡过程，由于聚合物的粘弹性，流动过程中建立的剪切应力、法向应力和大弹性形变在固化过程中不能完全松弛，在制品中形成残余应力和取向，对制品的机械和光学性能有着重要影响。

But from the point of view of the relativity theory, time as well as space is changed by passing from one c.s. to another, and the Lorentz transformation considers the transformation properties of the four-dimensional time-space continuum of our four-dimensional world of events.

但是从相对论的观点看来，时间和空间从一个坐标系过渡到另一个坐标系时都是要改变的，而洛伦兹转换就是考察事件的四维世界的四维时空连续区的转换性质的。

In order to solve Oldano-Barbero paradox caused by the splay -bend elastic constant k13 in the continuum theory of nematic liquid c rystals,we determine the distribution of the director in the planar al ignment nematic liquid crystal cell by means of finite elements method .

Although attitudes to these questions span the continuum from nativism to learning theory, answers remain elusive.

虽然如今对这些问题的看法跨越了传统的先天学习理论，但答案仍然很渺茫。

A continuum model was established by introducing Newton stress formula into the elastic-plastic model to describe the deformation behavior of material in bonding zone. Based on the model, the mechanism of plastic deformation and the influence of detonation velocity on plastic deformation were analyzed and compared with experiments.
