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。

Nature sent him into the world strong and lusty, in a thriving condition, wearing his own hair on his head, the proper branches of this reasoning vegetable, till the axe of intemperance has lopped off his green boughs, and left him a withered trunk, he then flies to art, and puts on a periwig, valuing himself upon an unnatural bundle of hairs, all covered with powder, that never grew on his head; but now should this our broomstick pretend to enter the scene, proud of those birchen spoils it never bore, and all covered with dust, through the sweeping of the finest lady's chamber, we should be apt to ridicule and despise its vanity.
刚来到这个世界上时,它是多么的遒劲有力,多么的活力十足,欣欣向荣。头上长着与生俱来的嫩枝,枝叶繁茂,然而,人类的斧头无节制地将它的枝干砍掉,直到留给它一个枯萎的树干。然后,它只得求助艺术,戴上一丛自己看来并不自然的"假发",而且那假发永远也不会生长。自己则完全掩埋在灰尘中。但是,我们的扫柄也应这样登场——把桦木的枝条安在自己身上,并且为之洋洋自得吗?它们身上覆盖了尘土,尽管还是最尊贵的夫人房里的尘土。即便这样,它的虚荣心,也应该受到我们的嘲笑与鄙视。

As soon as passes through contacts Mo Yan's novel, we are very easy to discover ""the Gaomi northeast township"" this specific hypothesized space has nearly become the writer novel world pronoun, if again the deep level carries on to it inquires, we can discover William Faulkner, Yasunari Kawabata, Garcia de and so on the multitudinous western master's shadow; However accumulates speaking of writer's culture, any writers all not impossible completely to get rid of the native place culture influence which he grows, he inevitably must derive the folk tradition, inherits the most candid narrative spirit; Moreover, the writer own childhood experience had decided he has the unique emotion tendency, and has the profound influence to the writer unique esthetic consciousness way.
一经接触莫言的小说,我们很容易发现"高密东北乡"这一特定的虚拟空间几乎成为了莫言小说世界的代名词,如果再深层次地对其进行探询,福克纳、马尔克斯等众多西方大师的影子将会一一闪现;然而就作家的文化积淀而言,任何作家都不可能完全摆脱生长于斯的本土文化的影响,他必然要汲取民间传统,承继最本真的叙事精神;另外,作家自身的童年经验又决定了其独特的情感倾向,对作家独特的审美知觉方式有着深刻的影响。接下来,论文从叙事学角度对莫言叙事艺术的具体特征进行了归纳与总结。

Zhu Wei makes no bones about his love of gongbi (fine-lined traditional style) painting. In his work, the mode of gongbi as a form of expression serves to bring out the idea and atmosphere of his imagery. His use of line, colour and texture shows continuity of the traditional practice, but because his conceptualisation originates from reality, a flavour of contemporary time is palpable in his works.
朱伟毫不隐晦自己对传统工笔表现方式的偏爱,不过,在他的作品里,方式完全从属于画面所体现的观念及气氛所需,例如他在技法上——诸如线条、色彩、机理等等,皆与传统方式的延续有关,但由于他的观念是从现实中生长,因此他作品中强烈的当代气息扑面而来。

Her clothes spread wide; And, mermaid-like, awhile they bore her up; Which time she chaunted snatches of old tunes; As one incapable of her own distress, Or like a creature native and indu'd Unto that element: but long it could not be Till that her garments, heavy with their drink, Pull'd the poor wretch from her melodious lay To muddy death.
有段时间,她的衣裳使她像人鱼般的漂浮起来,那时,她口里只哼唱著一些老诗歌,好像完全不顾自己的危险,也好像她本来就生长在水中一般。可是,这种情况无法持久,当她的衣裳被溪水浸透之後,这位可怜的姑娘,就在婉转的歌声中被卷入泥泞中。。。

This prospective, nonrandomized, open study took place at a private dermatology practice. A sequence of four groups, each made up of 10 to 20 office patients with DSO, were treated with pulse-dosed oral terbinafine, 250 mg per day for seven consecutive days, at intervals of two, three, and four months. Treatment was stopped when the distally advancing new nail bed and nail had completely removed the mycotic defect, or when fungistasis had failed.
这项研究是在一家私人皮肤科诊所进行的,为一预期性、随机性的设计;试验组包含一系列的四组,每组都有10至20个DSO患者,每位患者都接受脉冲式口服terbinafine治疗:每天250毫克,连续7天为一个治疗期;治疗间隔为2个月、3个月及4个月,治疗直到受霉菌感染的甲床及指甲,以自然生长的方式,完全被更换,或是这项抑霉治疗法无效为止。
