It is concluded that, first, geochemical data of the surface soils can clearly distinguish two kind of soils, that is, juvenile soils, for example, purple soils, which inherits most geochemical characteristics of the parent rocks or materials, and anthropic soils, the geochemical characteristics of which have been greatly changed as the results of intensive impact from variety of agricultural uses. Second, different soils have typical indicator elements association respectively due to different parent rocks or materials and utilization, such as purple soils, yellow soils (low alkali and alkaline-earth metal contents and pH value), paddy soils (high organic element and heavy metal elements contents) and fluvo-aquic soils (high rock-forming accessory mineral elements contents) and so on. Consequently, it can be suggested that elements association is an important indicator for two key factors (parent materials and anthropic activities) of soil classification. Third, some differences exist between soil genesic classification and result of cluster analysis, because geochemical characteristics of surface soils can not completely represent the foundation applying to soil genesic classification, that is, condition and process of soil-forming, and soil property.
结果表明:浅层土壤的地球化学数据能较好地用来区分两类土壤,即紫色土一类的幼年土壤(在很大程度上继承了母岩、母质的地球化学特征)和受强烈人为活动水耕、早耕熟化的土壤(外来物质的不断加人显著地改变了浅层土壤原有的地球化学性质);(2)各类土壤因母岩母质和利用方式不同,各具明显的标志性元素组合特征,如紫色土、黄壤(低碱和碱土金属元素和pH值)、水稻土(高有机元素、肥料元素和重金属元素)和潮土等,因此,这些元素组合是土壤分类两个要素的重要参照系;(3)浅层土壤的地球化学特征不可能完整地体现成土条件、成土过程和土壤属性这三个发生分类依据,因此,聚类分析结果与发生类型之间存在一定的差异。

In the second chapter, elementary theories and ideas of one step forming inverse approach were described and warped modification method, implemented by Cook, was introduced into one step forming simulation and based on idea of surface spreading; new quadrilateral element modification arithmetic was put forward. By spreading warped quadrilateral onto plane in local coordinate system, a plane quadrilateral element whose shape and area were equal to original warped quadrilateral element was gotten and internal force vectors of four nodes and stiffness matrix of elements were improved to increase precision of simulations on this plane element.

And the westernized women's clothing formed, namely the women's clothing of Shanghai's style.2、 Westernized subject content that the westernization of the modeling element is the women's clothing, and modeling westernization of element clothing structure, clothing modeling form change that westernization brings of craft in fact: The westernization of the element of the surface fabric, on one hand influenced by western artistic style, on one hand textile technology, westernized result of technology of dyeing ; The auxiliary materials element is occidentalized to followthe direct result of western fashion , aesthetic change.3、 Key point that Shanghai women's clothing is westernized that widewesternization is the Republic of China period, occidentalize to make the wholeform of the women's clothing changed into the Western-style S type from thetraditional H type in wide type, the change of such external form is the widecultural transition to narrow clothes decorations culture of clothes decorations infact.4、 In the westernized course of the women's clothing of the Republic of ChinaShanghai, 1920 times rely mainly on the fact that the dress is matched andoccidentalized ; 1930 times rely mainly on occidentalizing in modeling ; And1940 times rely mainly on the fact that the auxiliary materials are occidentalized .
局部西化女装是在保留部分传统女装构成元素的基础上,通过造型元素西化、面料元素西化或辅料元素西化,而形成的西化女装,即海派女装。 2、造型元素的西化是女装西化的主体内容,而造型元素的西化实质上是服装结构、工艺的西化带来的服装造型形态变化;面料元素的西化,一方面是受到西方艺术风格的影响,一方面是纺织技术、染色技术的西化结果;辅料元素西化多是追随西方流行时尚、审美变化的直接结果。 3、廓型的西化是民国时期上海女装西化的关键所在,廓型西化使得女装的整体形态由传统的H型转变为西式的S型,这种外在的形态的改变实质上是宽衣服饰文化向窄衣服饰文化的过渡。 4、民国上海女装的西化过程中,1920年代以服饰搭配西化为主;1930年代以造型西化为主;而1940年代以辅料西化为主。

In this dissertation the"Penalty"finite element method was employed to compute the velocity of the three-dimensional flow of power-law fluid in a profile die. In order to decrease the needed computer memory and raise the stability of numerical simulation, a set of decoupled methods such as PFEM, pseudo-body force method and transformation of momentum equation to the elliptic equation was developed to establish the general finite element equations to compute the distributions of velocity and viscoelastic stress of the three-dimensional viscoelastic flow of the Phan ThienTanner fluid in a profile die. During numerical simulation of the extrudate swell of the PTT fluid, the flow in the die and out of the die was analyzed separately, which demands less computer memory. The key techniques used in numerical simulation of the three-dimensional extrusion from dies such as decision of boundary conditions, creation of initial velocity field, selection of penalty factor, high Weissenberg number problem , regeneration of the free surface were studied in detail.
