After analyzing, some deduction is confirmed. First, the product hasapproached import very much, not only in outer dimension, but also on mainproperties. Second, best weaving-process parameter: symmetry degree is0.5～1, back roll height is 6cm more than front one. Third, weavingpreparation process: heddle draft is section, reed-in uses special yarns.Finally, the product can match import one that using 2/1 twill as basicweave, and 60～70D nylon as material, and 60 roots/cm.

K. H. Roscoe and his fellows of Cambridge University established the first elastoplastic model of soils which is based on classical plastic theory in 1963. However, due to the complexity of soils, the models that based on the classical metal constitutive theory or its modification accounting on the nature of soils have still much limitation when used to express the soil mechanical behavior. For example, the Duncan-Chang's model based on the generalized Hooke's law can not express the dilatancy of the soils. The uniqueness assumption of the direction of the incremental plastic strain in the classical plastic constitutive theory is not in agreement with some soil experiments.

但由于土的复杂性，目前以传统的本构理论为基础考虑土的一些特性而建立的模型在反映土体的力学特性上还存在很大的局限性，如建立于广义虎克定律基础上的Duncan—Chang模型不能反映土的剪胀性，传统的塑性本构理论中认为塑性应变增量方向具有唯一性的假设与一些土体的试验结果不符合。

From the author's study, we can know that: The survival and multiplication of human are the most basic start in traditional demiurgic process. The way to use material is a way of demiurgic process, It based on material's characteristics and immanency. The precise and careful attitudes of designers are the basis to represent the beauty of materials sufficiently.

通过以上这种过程的研究，了解到：在传统造物中，人的生存和繁衍是取材造物的最根本出发点；材料的使用方法实际上是造物过程的一种表现，它以材料的本质特征和内在规律为基础；造物者的严谨精细的工作态度则是充分展示材料美感的技术基础。

Then on the basis of western existential, we analyze definite meaning of the existential, explore the existential philosophy of the traditional philosophy plight of abandoned and beyond. Basing on this demonstration of the praxis category with the existential meaning. Marx pointed out in the innateness of human, natural fact, the natural state of survival reached the general attention, existential significance of praxis can be fully reflected. And explained that Marxist philosophy in the modern existential philosophy of the founders position.

之后以西方生存论为基础对生存论的内涵进行了分析和界定，探讨了生存论哲学对传统哲学理论困境的扬弃与超越，在此基础上通过考察马克思在对人的本然、实然、应然的生存状态的总体性关注中所体现的实践范畴所具有的生存论意蕴，并说明了马克思哲学在现代生存论哲学中的奠基性地位。

On the basis of an analysis of the present profile of automobile consumer credit in China,a discussion is done on the meaning of its development. This thesis introduces the development of the market of automobile consumer credit overseas, and finds out the reasons why overseas automobile consumer credit leads to the successful development of automobile industry. It also analyses the causes of the slump in the market of automobile consumer credit in the country in aspects of influential elements such as economy,policies,society,consumption norms and so on. It has a deep discussion on some obvious problems in this field. For example,the market of automobile consumer credit is of no scale; the prices of automobiles are high; taxes are heavy and expenses are too much; average residents still have low income and no definite balance between income and predicted expenses; there is no perfect social credit system and individual credit system; there is not enough awareness of credit among the public. Taking theories in the area of industrial economics into consideration,it proposes basic measures of promoting the development of consumer credit in China: building up a credited society,a perfect and sound personal credit system.With credit database as the platform,all parties will be able to share information,improve the credit database,relevant regulations and laws as well as a risk warning system,thus operation and management of the operating entities will be improved,the cost of the practice of consumer credit will be reduced; strengthen the innovation of present financial system,develop financial products corresponding to different groups of customers,improve services,perfect the mode of "bank+insurance+automobile agents",make full use of the interne,adopt the practice of turning credit into securities.

OD estimation was divided into fixed steps, with every step containing a bi-level programming. The upper-level problem was a generalized least squares estimator, while the lower level problem was a stochastic user equilibrium model. Namely, based on generalized least squares estimator and stochastic user equilibrium, a new estimator of the OD matrix was proposed by target matrix and traffic counts updating.

将OD估计分为固定的步数，每一步都是一个双层规划，上层为广义最小二乘估计，下层为随机用户均衡分配模型，即以广义最小二乘估计和随机用户均衡分配模型为基础，通过更新估计模型中目标矩阵和实测路段上的流量来估计OD矩阵。
