First the math theory of machining simulation is studied, and the set structure of NC machining simulation system whose components, including time, input, output and so on, are defined. Hereby we set up the hierarchy structure, the logical structure, the static model and the dynamic model of simulation system. The construction method of sweep entity of cutter and rotation parts is researched, and their differential geometry invariants are calculated. NC code is unscrambled, and the recursion division arithmetic of time segment is put forward, which is the driven data of the movement or rotation parts. The CLDATA should be interference-free. To examine if there is interference between cutter flank and the work piece, an arithmetic that discussed the existence of intersecting curve between them is put forward. To examine if there is interference between two turrets, an arithmetic that discussed the existence of intersection set between two polygons is put forward.

首先研究加工过程仿真的数学基础，然后定义数控加工仿真系统的集合结构及时间集、输入集、输出集等概念，建立加工仿真的层次结构和逻辑结构，阐述双刀车削仿真系统的静态模型和动态模型建立方法，分析刀具扫描体和旋转部件扫描体的建立方法及其微分几何性质；研究NC代码解读技术和双刀加工时间段递归子分划技术，为驱动各仿真单元作数据准备；通过讨论后刀面和工件表面交线的存在性判断刀具后刀面与工件间是否干涉，通过求多边形的交集判断刀架与刀架是否干涉。

In its broader context, social realism can be regarded as something of an international phenomenon, including the Wandering of Russian artists in the 19th century, the Mexican mural paintings of the 1930s and the so called Ashcan art of America, spanning from the turn of the 20th century to the 1930s. The difference between social realism and socialist realism is that the former is free from the influence of national ideology and control; it is the result of independent thought and criticism by freethinking intellectuals.

社会现实主义，从广义上讲应被视为一种国际现象，它包括19 世纪俄国"巡回画派"、1930年代墨西哥的壁画以及大体发生在美国世纪之交到30年代的所谓的"垃圾桶画派"，它与社会主义现实主义不同的是，前者不受国家意识形态和艺术体制的控制，它是自由知识分子对社会现实的独立思考和批判。

驾一页扁舟沿着历史的长河去回顾文明的历程吧，听埃及尼罗河上的船歌，闻西亚两河流域的稻香，在南亚的印度河、恒河感受一次圣浴，到中国的黄河、长江流域撒网，观古希腊的爱琴海城邦的民主灯火，品大洋彼岸的密西西比河的自由琼浆，让我们领略惊涛拍岸、水天一色，令尊贵的心灵荡气回肠

Small intestinal biopsies showed subepithelial collagen deposition with varying degrees of villous atrophy and varying numbers of intraepithelial lymphocytes. Four patients had previous biopsies showing enteropathic changes without collagen deposition. Seven cases were associated with collagenous colitis and 1 also had features of lymphocytic colitis. Three patients also had collagen deposition in gastric biopsies. One case was associated with lymphocytic gastritis. Celiac disease (CD, gluten-sensitive enteropathy) was documented in 4 patients. Five patients made a clinical improvement with combinations of a gluten-free diet and immunosuppressive therapy. Two patients died of complications of malnutrition and 1 of another illness. Clonal T-cell populations were identified in 5 of 6 cases tested. Four of these patients improved clinically after treatment but 1 has died. Collagenous sprue evolved on a background of CD in 4 cases. There was no history of CD in others and these cases may be the result of a biologic insult other than gluten sensitivity.

小肠活检表现为上皮下胶原沉积，绒毛萎缩程度不一，上皮内淋巴细胞浸润数量不等。4例患者以往曾做过活检，表现为其他肠病改变，并没有胶原沉积。7例患者合并胶原性结肠炎，且1例还有淋巴细胞性结肠炎的特征。3例患者胃活检也发现有胶原沉积。1例患者合并淋巴细胞性胃炎。4例患者有乳糜泻（CD，谷蛋白敏感性肠病）病史。5例患者经无麸质饮食和免疫抑制治疗后，临床症状有所改善。2例患者因营养不良合并另一种疾病而死亡。6例患者做了T细胞受体基因重排，其中5例发现有克隆性T细胞群，这5例中有4例治疗后临床症状加重，且1例死亡。4例患者在CD的基础上病发胶原性口炎性腹泻；其余患者无CD病史，他们的发病也许是生物源性损害，而非谷蛋白敏感。

Administration of Foreign Exchange Foreign Exchange Management Department of Chongqing Liu Liu suggested that the adoption of laws and regulations, a substantial increase in foreign real estate industry registered a total investment of capital in proportion to the total investment to adapt; explicitly request the registered capital In the operating period of time must be stabilized to maintain a high ratio of external debt in order to reduce the free flow of funds may impact the real estate industry.

Rooted in Chinese modernization practice, deriving from Chinese traditional values, drawing the reasonable thoughts of pragmatism, developing the usefulness and discarding the uselessness of the value concept of the western market economy, Collectivism values under socialist market system is the perfect integration and high unity of individual and group、the interest of individual and collective, can be interpreted as follows: relation between individual and collective interest is the nucleus, mutual interests is the premise, impartiality and justice is the lever, utilitarian principle is the motive power, dedicatative spirit is the direction, competition and practice is the means, common prosperity is the realistic pursuit, Communism is the goal. It is no doubt that collectivism will play an important role in Socialist modernization construction, stimulate Chinese creative enthusiasm, enrich social material and spiritual wealth, stride to the boundary ideal society of"The United Body of Free Man".

植根于社会主义现代化实践，渊源于中国的传统文化、汲取了实用主义的合理思想，扬弃了西方市场经济的价值观念，以个人与集体利益关系为轴心，以互利互惠为前提，以公平和公正为杠杆，以功利原则为动力，以奉献精神为导向，以竞争务实为实现手段，以共同富裕为现实追求，以共产主义为价值指归，实现了个体与群体、个人利益与集体利益的完满结合和高度统一的社会主义市场经济条件下的集体主义价值观，必将对我国社会主义现代化建设发挥重要的价值导向作用，必将以其特有的功能激发起人们的创造热情，丰富社会的物质和精神财富，以最终向着"自由人联合体"的理想社会境界迈进。

The Guidant-independent Teaching Model of High School Biology sticks to the principle of student-oriented so as to build the classroom atmosphere of democratic, fair, free and open, active the effective teaching interaction and enable students to participate actively in classroom teaching and develop the activeness and independence of students. The Guidant-independent Teaching Model adheres to the rule of students-centered. It proposes teaching-after-self-learning, teaching-follow-self-learning, teaching-promote-self-learning and enables students to learn by themselves at first through reading, self-thinking, questioning, group-discussion and forum.Thus, the independence and imitativeness of students will be achieved.We also lay emphasis on the development of the abilities of self-study and co-operative study so as to get the teaching goal of "learn how to learn" and promote the development of the independence of students.

Through the experiments of three kinds of models mentioned above, the structural deformations of "outflow-extension","strike-slip-extension" and "uplifting-extension" are studied and some viewpoints involving that the plastic flow in the lower lithosphere controls the extensional structures are stated as follows:(1) Regional extensional structure does not result from the direct extension along the upper crust, but from the plastic flow in the lower lithosphere and its dragging and stretching the upper crust;(2) Deformation of continental extensional structure resulted from the active uplifting of mantle is conditional that the significant extension occurs only in the models with free- or outflow-boundary condition on both sides, whereas the passive uplining of mantle exists widely, because it is an inevitable consequence of the efiect of thermo-gravity isostasy;(3) Strike-slip shearing in the lower ductile lithosphere, including site-restricted and site-unrestricted shearing, can result in various types of extension structures;(4) The"graben-horst"type extensional structures can be formed in difierent mechanisms, including outnow-extension, shear-extension, uplifting-extension and their synthetical action.

通过上述三种模型的模拟试验，比较系统地研究了"泄流-伸展"、"走滑-伸展"和"上隆-伸展"等构造变形，提出岩石圈下层塑性流动控制了各种伸展构造变形的观点，主要包括以下几方面：(1)区域性伸展构造不是上层直接受到拉伸，主要是下层流动牵引上层伸展；(2)地幔主动上隆引起大陆伸展构造变形是有条件的，需要侧边伸展或不受约束的边界条件，而被动上隆广泛存在于地壳断裂或减薄部位，是热和重力均衡的必然结果；(3)下层塑性流动中的走滑剪切，包括限位剪切或非限位剪切，可以引起不同型式的伸展构造；(4)总结了"堑-垒"型伸展构造的多种成因机制，包括泄流、走滑、上隆及综合作用均可形成"堑-垒"构造，但组合形式不尽相同。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
