This thesis contributes to geometry compression in the following aspects: Proposes a method of progressive spherical mesh parameterization based on local parameterization by directly projecting the deleted vertices to its neighborhood. Based on spherical mesh paramterization, an adaptive subdivision remeshing method by progressivly redistributing of sampling points is proposed, by this means, the main geometry information of the original mesh can be captured with only a small amount of samples, it can also be used in mesh simplification. By regarding attributes binded on mesh vertices as geometry signals and transferring them onto a uint sphere by means of spherical mesh parameterization, meshes with different attributes are compressed with spherical wavelet successfully with high compression rate. As a kind of lossy geometry compression technique, two mesh simplification algorthimes are also presented in this thesis.

归纳起来，本文的主要贡献有：提出了以直接投影局部参数化方法为基础的网格累进球面参数化方法；在网格球面参数化方法的基础之上，提出了一种基于累进优化布点方案的网格细分采样方法，该方法可以用很少的采样点就可以捕获到网格的主要特征，因此我们也将其用于后面的网格简化工作当中；通过将网格顶点上定义的各种属性看成几何信号，并以网格球面参数化为手段将几何信号迁移到单位球面上，从而成功地实现了用球面小波对各种几何信号的压缩；作为一种有损压缩方法，本文还提出了基于统一距离的网格简化算法和基于重采样的网格简化算法。

The most common causative strain of gallstone pancreatitis is Bacterium coli. The drug-resistant strain emerges maybe due to bacterium immigration and delitescence in gallbladder mucosa.

胆源性胰腺炎感染细菌主要以大肠杆菌为主，耐药菌株的出现可能与细菌向胆囊黏膜迁移并发生变异，以L型细菌的形式潜伏于胆囊有关。

04 Moreover, demographer s see the continuing shift south and west as joined by a related but newer phenomenon: More and more, Americans apparently are looking not just for places with more jobs but with fewer people, too.

而且，人口学家发现，向南部和向西部的不断迁移还伴随着一种相关却又较新的现象：越来越多的美国人显然不再仅仅寻找有更多工作机会的地方，也在寻找人口稀少的地方。

If it is really needed to demolish, move, rebuild or close the environmental sanitation facilities due to special causes such as construction etc., the construction entity or other relevant entity shall report to the municipal or district administrative department of sanitation for approval, in the case of demolishment or close of environmental sanitation facilities, scheme on future construction shall also be presented.

因建设等特殊原因确需拆除、迁移、改建、封闭环境卫生设施的，建设单位或者其他有关单位应当报市或者区市容环境卫生管理部门批准；拆除、封闭环境卫生设施的，还应当提出补建方案。

The study of population migration is an important issue of current sociology ,demology and economics etc.

人口迁移一直是社会学、人口学、经济学等学科研究的一个热点，国外学者对此进行了大量的研究。

He also said that forced transfers of staff, which critics say demoralized workers,would be applied only in exceptional circumstances.

他还说，只有在特别的情况下才会强制性将员工迁移。一些批评家称这影响了员工的士气。

Objectives: To study the offcts of the polymerization and depolymerization of intracellular F-actin on cancer cellular morphology, migration and invasion.

目的：为探讨癌细胞内F-actin的解聚与聚合对癌细胞的形态、迁移、侵入的影响。

Presently, knowledge of sorption and desorption is limited, which results in significant errors in environmental prediction of organic compounds.

目前，对吸附机理及影响因素认识的局限性，使得有机污染物的迁移转化和归宿模型在实际水环境中的预测存在较大的误差。

If you put your detestable idols out of my sight and no longer go astray

耶和华说，以色列阿，你若回来归向我，若从我眼前除掉你可憎的偶像，你就不被迁移。

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。
