The proposed approach is verified by two cantilever beam experiments under ideal boundary conditions and uncertain end conditions, and the approach presented here is suitable for crack identification in engineering even if small frequency measuring errors exist.

对于理想边界条件下的裂纹参数识别，在测量频率存在小误差情况下，该方法仍能给出比较满意的结果，对于非完全固支边界条件下的裂纹参数识别，利用本文方法能得到比Narkis的方法更精确的裂纹位置识别结果。

It can be demonstrated that two methods proposed in this paper, namely the method of selecting the additional parameters and the method of the rider estimation considering the parameters as weighted observations, ars of great importance to solving the ill—conditioned problem of the normal equati...

试验结果表明，本文研究的模型参数选择法和参数加权岭估计法对于解决法方程组的病态问题以及对于提高GPS双次差短弧法定位结果的精度和可靠性是很有意义的。

Although the personality is protected through the rights form, an ultimate defect is in the concept of the personality interestbecause of its illegibility and the depending on the theory of the personality.

虽然这在一定程度上实现了通过权利模式对于人格的保护，但是由于"人格利益"概念本身的模糊性和对于人格理论的依赖性，人格利益作为人格权法律关系之客体具有根本性的缺陷。

Finally, by studying on using saw blades with different matrices cutting different stones, a basic compatibility rule about matrices and stones was concluded, say, when cutting a hard, high quartz and high alkalifeldspar content and strong bonded stone, a high impact strength and low wear-resistance matrix should be chosen; otherwise, when cutting a soft, low quartz or no quartz content and weak bonded stone, a high bending strength, low impact strength and high wear-resistance matrix should be chosen.

最后，通过对不同性能结合剂的锯片切割不同石材的切削寿命和磨损状态分析，得出了锯片结合剂性能与岩石性质之间的一般性匹配原则：即对于坚硬的、高石英含量的花岗岩，宜选用高强度、高冲击韧性、低耐磨性和对金刚石具有良好粘结性能的结合剂；对于低硬度、无石英或低石英含量的易切削花岗岩，宜选用高强度、高耐磨性和低冲击韧性的结合剂。

The Roman word is better, impedimenta. For as the baggage is to an army, so is riches to virtue.

古罗马用的 impedimenta "辎重"一词就更好，因为辎重对于军队，如同财富对于美德。

In the paper, river and the downstream area of dike are regarded as a whole system, and hydraulic model of coupling 1-D river and gradual dike-break is established, therein the Preissmann implicit difference scheme is applied to Main River, and the FVM is applied to the breach and polder. On the basis of FVM and unstructured grids, TVD ?

本文将河道与堤坝下游区域视为一个整体，对于单一河道采用Preissmann四点隐式差分格式计算，对于溃口及圩区采用有限体积法，建立了一维河道与堤坝渐溃耦联的水力模型，也是一维、二维耦合的水流模型。

The LCM releases to regardless incise to the high quality of super and hard material, still beating bore to the diamond, all having very important meaning.

LCM的推出无论对于超硬材料的高质量切割，还是对于金刚石打孔，都具有非常重大的意义。

4The LCM release to regardless incise to the Gao quality of super and hard material, be still for diamond dozen bore, all have very graveness of meaning.

LCM的推出无论对于超硬材料的高质量切割，还是对于金刚石打孔，都具有非常重大的意义。

Kuhn\'s thought roots in historical principle, especially how to appraise the different historical periods and the historical events which displays the rational historical tendency. This has the important influence on Kuhn\'s Incommensurability.

历史主义成为库恩思想的大背景，特别是其中对于不同历史时期和历史事件如何评价的观点，表现出理性历史化的趋势，对于库恩提出的不可通约性有重要的影响。

The flow of incompressible viscous fluid is controlled by Navier-Stokes Equations.The qualititave analysis of the solutions of the equation is important to the studies of bifurcation problems and numerical solutions of the equations.

对于描述不可压缩粘性流体流动的Navier-Stokes方程，其解的定性分析结果对于该方程的数值求解及其分歧问题的研究都是十分重要的。

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。
