Firstly, based on the Duhamel integral and dynamic reciprocity theorem, the generalized Duhamel integral expression is written to a point in the half infinity space under moving load. Secondly, the train load is considered as a series of centralized loads with fixed distance. The dynamic response expression of a point in frequency domain and frequencywavenumber domain are derived out through the Floquet transform and Fourier transform under a moving load, and then the dynamic response of a point is gotten ...

以Duhamel积分为基础，首先应用动力互等定理，得到了移动荷载作用下，半无限大弹性连续介质空间上任意点的动力响应的广义Duhamel积分表达式；然后将列车荷载简化考虑为一系列具有一定间距的集中荷载，采用Floquet变换、Fourier变换等方法，得到了一个集中移动荷载作用下任意拾振点ξ的动力响应在频域和频率波数域内的表达式，进而由叠加原理得到列车荷载作用下的动力响应解；最后，通过算例说明该算法的适用性。

The surface of conventional engineering part is composed of simple analytical surfaces and four-boundary ruled surface primarily. Therefore a point cloud segmentation method based on those feature surfaces is proposed. Several algorithms to identify the simple analytical surface feature are investigated and discussed. The theory of fitting scattered point to B－Spline and Bézier surfaces is introduced and a fitting method based on four boundary and point set is also discussed. Moreover, anew method to recover the fix-radius rolling ball blend is proposed and discussed in detail.

The results of optimization growth model with land input based on the RCK Model implied that when the economy convergences to one point in a saddle-shaped path, at this point the capital per capita and the consumption per capita will be unchanged, and higher efficient land input per capita will bring higher capital per capita and higher consumption per capita at that point.

在最优增长模型中，我们以RCK模型为框架，分析了当经济以鞍形路径收敛到某点时，该点的有效人均资本和有效人均消费水平，发现有效土地资本投入的增加使得经济收敛到一个具有更高有效人均资本水平和有效人均消费水平的收敛点。

The graphical model for point pattern matching in JT algorithm is proved sensitive to the outliers in template point-set recently. To efficiently solve the problem, this paper sampled on the point in the separator, and derived the relationship between the times of the sampling and the ratio of the outliers.

为解决概率图模型匹配算法对模板点集中的外点敏感的问题，对隔离子进行了采样，并推导出采样次数和模板点集中的外点比例关系，以保证隔离子中的点能最大概率地为内点，使得推理算法中每个点的信息能得到传递。

From this point of view,Savigny is not the starting point of thediscussion of abstract transfer,to the contrary,he is near the ending point of a theoreticpedigree.
