非弹性的

The concept, symbolic play deficit in autism, was partly supported by this study. Most of children with autism could gradually develop the capacity of dual representation; and moreover, in the case of high functioning autism, symbol comprehension of triune representation remained intact. Their difficulties are more on the flexibility of functional or symbolic spontaneous play, rather than symbolic comprehension.

总结而论：自闭症儿童游戏能力的缺陷在本研究中得到部分支持，随著年龄成长，他们能逐渐发展出双重表徵的能力，三重表徵的能力发展在高功能自闭症儿童中亦未有困难，自闭症儿童象徵能力的缺陷，仍较集中在自发的功能性或象徵性游戏能力中弹性使用的部份，而非象徵理解的部分。

The influence of initial imperfections on the stability ofcomposite laminated plates was studied by solving the nonlinear governing equations for laminated plates with elastical restraints subject to in-plane loading using the energy variational principle and nonlinear geometric equations incorporating the initial imperfection. The governing equations were solved using generalized Fourier series to obtain the effect of the non-uniform order term.

为深入研究初始缺陷对复合材料层板稳定性的影响，利用能量变分原理和考虑初始缺陷的非线性几何方程，建立了具有弹性约束的层合板在面内载荷作用下的非线性稳定性控制方程组，运用广义傅立叶级数法对其进行求解，并进一步获得了影响非线性稳定性控制方程组的性质的非齐次项。

The result showed that,if only the necessary but insufficient condition,the equilibrium condition ,was adopted to deal with the infinite uncertain boundary condition,the solution to the stress was non-unique due to the fact that the boundary problem here was a mal posed mathematic problem.

通过两个典型的半无限体实例，对水平表面作用无限均布压力下弹性地基的应力和位移解答进行研究，结果表明：对边界条件不明确的无限边界仅采用解答的必要非充分条件——平衡条件来等效处理，其应力解答不是唯一的，因为此时该边值问题不是一个适定的数学问题。

This equation is changed into the standard form of the Mathieu equation by using Galerkin method.

应用Galerkin原理将该屈曲方程整理为Mathieu方程的标准形式，并利用Mathieu方程解的稳定区域与非稳定区域的分界，即方程系数的本征值关系，得出磁弹性问题屈曲临界状态的判别方程。

Then, use Galerkin principle to put the stability equation in order for the special function the Mathieu standard form, and utilize the boundary of the Mathieu solves' steady area and unsteady area , namely special relationships of and,draw the discrimination equation of losing the magnetoelastic steady critical state.

然后，应用Galerkin原理将稳定性方程整理为特殊函数马丢方程的标准形式，并利用马丢方程的稳定解区域与非稳定解区域的分界，即系数和的本征值关系得出了磁弹性最低失稳临界状态的判别方程。

In 1987, Kane et al.〓investigated the dynamics of a cantilever beam in a non-inertial reference frame.

建模时如果不考虑这种因素的影响，将会导致错误的结论。1987年，Kane〓对非惯性系下的旋转弹性梁的动力学特性进行研究，指出在转速较大的情况下，按零次近似建模理论进行仿真计算会得到梁的挠度趋于发散失稳这样一个错误的结论。

The shaping course of Fine blanking is very complex. Material forms a local plastic cutting area between punch and bottom die, and brings violent plastic flow under the effect of press stress. The grad of stress and strain is great, and it is an unstable transmutation process that came through an elastic distortion, plastic distortion and cut rupture.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
