As it can be expressed easily by argument equations, we use the conicoid as the criteria of points" classification. Based on the point"s normal and the adjacent field, corresponding to the conicoid equation such as plane, ball and cylinder, we search the points that fit the equation along the adjacent field. Using this method, we realized the automatic classification of unorganized points.The experiments using the algoritlim and criteria approved from this thesis are also carried out.

In this paper, the research object is the XM18 spherical generator, in order to improve the dynamic behavior of the machine tool, the following aspects have been studied in this thesis: Firstly, based on the elasticity theory and finite element analysis theory, the finite element models of the lathe bed, dovetail, dovetail shelf, headstock, fanlike plank and millhead shelf, which were the main parts of the spherical generator, were built up using ANSYS9.0. And based on the modal analysis theory and FEM technology, the free modal and the constrained modal analysis of the main parts were studied. Accordance to the analytical results, put forword methods to optimize the key parts.

From Karlsson's formula and the polar effect, we realize that the half periodic parameter of redshift is 0.206, in theory, we finally explain why the great wall is at redshift Z=0.079 in redshift space; We have defined quasar as the early star nearby the position poles and opposite poles, and given the answer for two difficult problems of theirs; Based on the course of explanation for redshift space, we have reason to think that our universe might be the linear expansion hyperspherical universe.
