This paper presents an IFMC CAD model that consits of a geometry model and a material model, in which the geometry space acts as a base space and the material space acts as a bundle space. In this CAD model, the geometry model is based on the non-manifold model. In addition, a half-face data sturucture, which is derived from the half-edge data structure with the non-manifold feature of IFMC taken into account, is adopted to represent the geometry and topology information of the component. For the material model of IFMC, this paper focuses on the FGM component representation firstly and present a simplex-subdivision based CAD data exchange format, in which the material information is represented as a (n-1) simplex and material distributing feature is represented by the interpolation on the simplex-subdivision. Based on those, a part-building orientation optimization algorithm and an adaptive slicing algorithm for FGM component are presented in the paper. For the IFMC material model, the IFMC material information representation is divided into a meso-scale and a macro-scale representation. In the meso-scale, a concept named parameterized periodic functional meso-structure is presented as a unique form to represent the FGM (the homogeneous materials are regarded as a special FGM), the composite and the functional meso-structure material. The model of PMS is a three-tuple that contains the space state informatation, the material parameter and the material meso-scale distribution feature. The macro-scale material information representation is similar to the FGM components by interpolation of the control parameter of the periodical functional meso-structure based on the simplex-subdivision. Through an example of manufacturing-oriented IFMC CAD data processing, it is proved that the IFMC CAD model and the material information representation and process method proposed in this paper can provide a reliable data support for IFMC digital concurrent design and manufacturing.

本文将理想材料零件CAD模型建立在以几何空间为底空间、以材料空间为丛空间的结构上，使用非流形几何模型作为理想材料零件几何拓扑模型的基础，并在半边数据结构基础上，针对理想材料零件的非流形特征局限内部边界上的特点，给出了一个半面数据结构来表述零件的几何拓扑信息；对于理想材料零件的材料模型，本文先从功能梯度材料零件的信息表述与CAD数据交换和处理入手，将材料信息表述为（n-1）维单纯形，然后通过对三维几何区域的单纯剖分，以插值的方式表述零件材料分布特征；在此基础上，根据功能梯度材料零件分层制造中对CAD数据处理的要求，给出了综合考虑零件几何特征与材料特征的生长方向优化算法和自适应切片算法；而对于文中所定义的理想材料零件，本文将其材料信息表述分解到细观和宏观两个尺度进行，首先给出了细观尺度上参数化的周期性功能细结构概念，以此来统一表述功能梯度材料（单质材料作为特殊的功能梯度材料看待）、复合材料和功能细结构材料；把周期性功能细结构模型化为一个包含空间状态信息、材料构成参数和材料细观分布特征参数的三元组，以表达零件的细观材料特征；对于零件宏观的材料变化特征，则同样在几何区域单纯剖分的基础上，通过对细观尺度上周期性功能细结构控制参数的插值来完成；通过理想材料零件CAD数据处理的算例，验证了本文中理想材料零件CAD模型及材料信息表述与处理方法完全可以为理想材料零件的数字化制造提供可靠的数据支持。

When the molar fraction of SnO2 is 83%, the main component of the coating isO2 solid solution with rutile structure. When the molar fraction of SnO2 is 44%, the main components of coating are theO2 solid solution with rutile structure andO2 solid solution with fluorite structure. When the molar fraction of SnO2 is 17%, the main component of the coating isO2 solid solution with fluorite structure. Annealed at higher temperature than 450 ℃, CeO2 is found in the coating containing 83%Sn, and there is not SnO2 in the coating containing 83%Ce, which suggests that fluoriteO2 has higher thermal stability than rutileO2. When the molar fraction of SnO2 increases, the dispensability of the coatings is improved greatly.

The thesis takes three chapters. It gives prominence to the dynamic construction process of value-cognition structure, stresses that Marx is not a passive thought container. His early thought is not a passive excrescence to be imperatively get rid of, but it's a positive pre-structure to understand the world. This pre-structure as a internal, basic and continually developed value-recognition structure that enable knowledge and ethics to be possible, stipulates an agreement on the path and direction of his last thought development. So Marx said:"The problem is not to rule off an impassable gap between the past and the future, but is to realize the past thought."

本文采取三篇结构，突出马克思价值-认知结构的动态建构过程，强调马克思早期思想不是需要摆脱的消极赘生物，而是理解世界的一种积极的"前结构"，这种"前结构"作为一种内在的、基础性的和连续发展的、使知识和道德成为可能的价值-认知结构，规约着马克思以后思想发展的路径和方向，以致连马克思本人也认为"问题并不在于从思想上给过去和未来划下一条不可逾越的鸿沟，而在于实现过去的思想。"
