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。

本文分为三部分，第一部分是一人公司理论与立法概要，主要介绍一人公司的概念、特征、类别及各国的立法例；第二部分全面论述我国应建立一人公司制度，首先，论述全面建立一人公司的理论依据，提出了团体性不是法人的本质特征，社团法人是以人为基础的法人；资本信用是公司的本质特征，一人公司可以具备资本信用；有限责任的基础不是所有权与经营权的分离，允许一人投资者享有有限责任并非对公司债权人极为不利的观点；接着论述全面建立一人公司的实践依据；最后进一步分析我国全面建立一人公司制度的必要性。

This article takes the Marxism Humanics and Western Stimulation theory as its foundation stone .It also takes the Marxism Humanics as its guide thought and philosophical foundation which constitute the Stimulation Management Mode . Through reflecting on the traditional Stimulation Mode and studying the logical foundation of stimulation of teachers in elementary and middle schools ,we deeply reflect on the Tradition Stimulation Mode and its thought and attribute the problem of stimulation strategy to the loss of the humanity and the pinch of the value pursuit .From the reality of Chinese culture and modern school culture .we use the essential thought in the Western Stimulation Theory for reference and set a definition on Stimulation from the philosophical view ,that is ,the subject takes the corresponding stimulation mode according to the understanding of the stimulated object needs ,acts on the motivation ,purpose and action of the stimulated and consequently satisfy the purpose of the subject .

本文以马克思人学理论和西方激励理论为理论基石，以马克思人学思想作为建构激励管理模式的指导思想和哲学基础，通过对传统激励模式的反思，通过对中小学教师激励的逻辑基础的研究和外在因素的研究，对传统教师激励模式及思想做深刻反思，将传统中小学教师激励策略问题归结为人文性的缺失和价值追求的匮乏，并从中国文化、现代学校文化实际出发，借鉴西方激励理论中的精华思想，从哲学的视角定义了激励的内涵是行为主体根据对激励对象需要的理解而采取的相应的刺激方式，作用于被激励对象的动机、目的、行为，从而满足行为主体的目的。
