The result shows that the phenomenon of the sudden jump of permeability occurs at the peak strength and keeps very low unchanged permeability before the peak strength for diorite. But limestone's permeability gradually increases with increasing deformation before and after the peak strength.

实验结果表明，闪长岩的渗透率在峰前很低且基本不变，在峰值强度时产生"突跳"现象，石灰岩的渗透率在岩石强度峰值前后随岩石变形逐渐增大。

Exponential dichotomy describes a kind of hyperbolicity of the system. That is, the state space can be decomposed into a direct sum of two subspaces, which are continuous and invariant. And with the time evolving forward, the system is exponentially attracting in one subspace and exponentially expanding in the other subspace.

指数二分性描述了系统的一种双曲性现象：状态空间可以分解成两个连续不变的子空间的直和，随着时间的正向变化，系统在其中一个子空间上表现出指数压缩行为，而在另一个上面表现出指数扩张行为。

The direction of luminiferous evacuation indicator is fixed in complex fire accident scene,that is difficult to play safe and effective role in the evacuation instructions.

发光型疏散指示牌的指引方向固定不变，在复杂的火灾事故现场难于起到安全有效的疏散指示作用。

Directional selection in disease field is the most simple, economic, and effective method for improving cotton resistance. Both land cotton and long-staple cotton high sensitive to the fusarium disease could improve its resistance in few years by this method and the farming properties were nearly unchanged.

试验证明，在供试材料中，不论是陆地棉的高感品种还是长绒棉的高感品种，经过在重病田或病圃中定向加压筛选，都可在几年内使其抗病性得到迅速提高，并保持其农艺性状基本不变。

The rearrangement characteristics of the Dirichlet series' sum-function with the same type is also discussed.

讨论了Dirichlet级数的和函数的型保持不变的重排特征。

With induction of precision order, the growth of Dirichlet series of rearrangement of the coefficients is investigated.

研究了狄里克莱级数引入精确级后系数经过重排的增长性，得到了有限级狄里克莱级数的系数经过重排后级和型保持不变的充要条件。

Head in the disk rotational speed and the speed of operation remain unchanged, the same time, head-to-disk can visit some of the region.

在磁盘转速和磁头的操作速度不变的情况下，相同的时间内磁头所能访问到磁盘的区域是一定的。

找到你自己的兴奋点并且你不变得单调--然后你就可以不再把没有条理当作未来生活的拐杖。

The results show that this kind of superplasticizer not only has high dispersibility, but also has the possibility to controlling slump lost.

结果表明，这类高效减水剂除具有很高的分散性(减水率达30%)外，还具有控制坍落度损失的功能(2小时内坍落度基本不变)。

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。
