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。

The information Radon coefficient wrap-around of the line on a finite field was caused by the modular arithmetic so that the Radon coefficient information in the periodic oscillations direction was processed with discrete cosine transformation, and other direction information was processed with wavelet analysis in order to reduce the wrap-around of rebuilding information. At the same time, according to the characteristic of the noise, one kind of denoising threshold selection plan was proposed.

The superior unilateral brain regions of information processing were the left forebrain and right epencephalon, which were the best match of both- side brain. Female athlete moods were more stable than the male athlete;besides, they were more active, having more powerful logic memory, and more rational thoughts.

T his, the low er the modulus w as, the better w as the athletic for m. T he fencing athlete with good marginal modulus was 6z.4%.w ith the nor oral being 3 }.6%.which indicated that the efficiency of Chinese fencing athlete brain ability of information processing was rather high.

Humanism" carried out in archival information communication is not only meant to follow with interest the audience's daily practical needs of archives and esthetic demands, but also, even more basically, meant to encourage the audience's consciousness and willingness of receiving archival information rather than their involuntariness and utilitarianism. The real essence in the communication effects of archival information lies in developing the audience's high-level esthetic view, archival sensitiveness and "EQ for seizing the value of archival information. On the other hand, the humanity in archival information itself, democracilization in the society and the advances of human spirits have all laid a solid foundation for the development of esthetic culture of archives.

在档案信息传播中贯彻"人本主义"，不仅指关注受众日常功利性的档案需要和审美情趣的要求以及传播者对这些需要和审美情趣的迎合与顺应，更根本性的在于促使受众对档案信息的接受超越实用功利性和工具性行为的限定，上升到一种自觉的境况，培养和引导受众形成较高水准的审美观念，从而增强对档案信息传播的敏感度和把握档案信息意义的"情商"，通过接受档案信息触发美好情绪和有益思考，充实和完善自身，这才是理想的档案信息传播效果应有之义。
