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 seeds of development of Husserl''s philosophy from the Philosophie der Arithmetik to the Prolegomena [i.e., the first volume of the Logische Untersuchungen, 1900] were immanent to his own thinking, so that the hypothesis of a traumatic effect of Frege''s 1894 review of his book and a consequent reversal of his mode of thinking is not only uncalled for but also unsubstantiated by the available evidence.
谢谢来信谈了胡塞尔反心理主义的特点。你说,他的转向是因为受了弗雷格的批评。不过,我看到份资料说,胡塞尔的现象学是逐渐发展起来的,不过相对来说有过几次转折和几次停顿。有两个例子足以说明:在出版了《算术哲学》一书之后,他随即同他所建立的心理学理论保持距离。评论家们以为这是接受弗雷格批评的一个突如其来的转折。然而默汉蒂( Mohanty ,1982)研究了他们两人的通信以后得出了完全相反的结论:胡塞尔哲学发展的种子,从《算术哲学》到《绪论》(《逻辑研究》的第一册,1900年),都是胡塞尔自己思想内在的东西。因此弗雷格1894年对他的《算术哲学》一书评论造成的创伤性的影响,并且随之造成他思想状态的转向——这个假设不仅纯属多此一举,而且并没有足够证据的支持。

The Automatic Control Valves ABS is ABS for short, which is based on the conventional brake system security technologies to enhance improved by controlling the brake hydraulic flaps to achieve control of the wheel locking, the braking process , only when the wheels tend to be controlled when locking, ABS will tend to locking of the wheels anti-lock brake pressure regulation; in the control wheel was not tended to locking, the braking Butterfly Valves process and the conventional system exactly the same dynamic system, the braking process, its work process is actually locking - release - Locking - release cycle of the working process, the vehicle is always in the critical state of locking of the roll gap.
而ABS是制动防抱死系统的简称,它是在常规制动装置基础上的加强改进的安全技术,通过控制刹车油压的收放,来达到对车轮抱死的控制,在制动过程中,只有当被控制车轮趋于抱死时,ABS才会对趋于抱死车轮的制动压力进行防抱死调节;在被控制车轮还没有趋于抱死时,制动过程与常规制动系统的制动过程完全相同,其工作过程实际上是抱死—松开—抱死—松开的循环工作过程,使车辆始终处于临界抱死的间隙滚动状态。

Therefore we have optimized the experimental system and the working status of instrument.2 The near-field SERS spectra and images for the [Ru_3]~(2+) molecule adsorbed on silver nanoparticle substrate were achieved. Based on the results, some specific phenomena for near-field SERS were found. By observing the near-field SERS spectra collected at different location at the nano-scale, the different spectral characteristics which are caused by the local environmental differences of molecules have been found. On the substrate, the highly SERS active sites are much more than SEF hot spots, and the distribution of them is not entirely consistent. This phenomenon could be explained by the influences of several factors including the different enhancement efficiencies existed for SERS and SEF, the quenching effects for fluorescence by the metal substrate and metal-coated tip, and the presence of different numbers of probing molecules in SERS and SEF.3 It is of interest that the near-field and far-field SER spectra demonstrate several distinctively different spectral features.
由于SNOM与SERS的结合在技术上将面临很多实际困难,例如近场激发信号极其微弱、纳米级微弱光谱的收集对实验精度和环境稳定性的苛刻要求等,因此我们对实验体系和仪器工作状态分别进行了优化。2获得了银纳米粒子SERS基底上[Ru_3]~(2+)分子在纳米尺度下的近场SERS光谱和图像,从中可以发现一些近场SERS效应特有的现象:通过观察不同位置得到的近场SERS光谱可以发现,在纳米尺度下,由于分子所处局域环境不同而体现出不同的光谱特征;此基底具有极高SERS活性的位点远多于表面增强荧光热点,且两者的分布并不完全一致。

试验研究结果表明,气压对覆冰绝缘子长串的闪络电压影响的特征指数与污秽绝缘子一致,覆冰可认为是一种特殊的污秽形式;在试验研究的串长范围内,闪络电压与串长成线性关系;绝缘子串覆冰以后的电位分布的变化是覆冰绝缘子串外绝缘特性下降的主要原因,但覆冰绝缘子串的局部电弧发展成完全闪络所需的时间比污秽绝缘子长,且受冰层的融化和冰凌状态的影响严重。
