In this dissertation, we develop the research work of the following three aspects based on existed work.First, using the scale-invariant property of multiscale model, i.e. Markovian among scales, a method of qth-order tree-based for multiscale representation of a class of 1-D stochastic process is presented. The multiscale stochastic model is established. The representation forms of parameter matrices, such as, the state transition matrix, the disturbance matrix, the initial state and the corresponding covariance matrix are deduced in detail. The multiscale sample paths based on distinctive order tree are presented by computer simulation.

本文在已有工作的基础上，开展了以下几个方面的研究工作： 1、根据多尺度模型尺度不变性，即利用尺度间的Markov性，给出了一类1-D随机过程基于一般q阶树的多尺度表示方法，建立了相应的多尺度动态模型，详细推导了多尺度模型中的状态转移阵、扰动阵、初始状态和相应的协方差阵，并通过计算机仿真给出了不同阶树的多尺度采样路径。

It is first found that there is an important difference in order-disorder of crystalline structure between the artificial pitchblende and natural pitchblende. Unlike natural pitchblende in which uraninite nanocrystals arrange in order, the artificial pitchblende only contains disorderly uraninite nanocrystals.

在国内、外首次发现此类人工合成沥青铀矿和天然沥青铀矿在晶体结构的有序—无序上存在重大差异：天然沥青铀矿中的纳米级晶质铀矿为有序排列，而人工合成沥青铀矿中的纳米级晶质铀矿则为无序排列。

This inversion of the value-positing eye - this need to direct one's view outwrd instead of back to oneself - is of tthe essence of ressentiment: in order to exist, slave morality always first needs a hostile external world; it needs, physiologically speaking, external simuli in order to act at all - its action is fundamentally reaction.

这种颠倒的价值目标的设定——其方向必然是向外，而不是反过来指向了自己——正好属于这种怨恨。奴隶道德的形成首先总是需要一个对立的外部环境，从生理学上讲，它需要外部的刺激才能粉墨登场，它的行为从根本上说是一种反应。

This inversion of the value-positing eye—this need to direct one's view outward instead of back to oneself—is of the essence of ressentiment; in order to exist, slave morality always first needs a hostile external world; it needs, physiologically speaking, external stimuli in order to act at all—its action is fundamentally reaction.

这种从反方向寻求确定价值的行动——值得注意的是，这是向外界而不是向自身方向寻求价值——这就是一种怨恨：奴隶道德的形成总是先需要一个对立的外部环境，从物理学的角度讲，它需要外界刺激才能出场，这种行动从本质上说是对外界的反应。

First, based on the analysis of the grid Reynold number, the necessity for adopting high order scheme is emphasized when there is the complex flows with strong separation and high parameters gradient regions. Then, according to the entropy increased condition, the third order ENN scheme is constructed. Meanwhile, a fast, effective, and simple implicit numerical method called hybrid flux splitting method is developed. After that, the one dimensional model problem with many extrema and Burgers equation are simulated. Through the comparisons with exact solutions, the accuracy and effectiveness of the ENN scheme are confirmed.

Therefore, this article first comparative analyze the branchesb between simple type theory and the theory of order type then described the reason is that Russell want to hold on his perspective of the position of philosophy, from simple theory of types to the theory of order types is a necessity across.

为此，本文首先比较分析了简单类型论与分支类型论在内容构建的区别，并进而从罗素实在论的哲学立场角度出发，分析了从简单类型论到分支类型论的跨越是有着必然性的。

First, this thesis introduces basic theory of CBR , and studies many aspects of typical part design case , such as case representation, case retrieval, retain etc. Second, regards design code as case code in order to integrate the case with geometrical and non- geometrical information, and realizes the parametric modifying function for 3D solid model in the condition of Pro/E. Third, for the purpose of making true of system's aided design requirement, this thesis brings forward to create part design knowledge base with AI language CLIPS, and integrates the rule based KB into the system; finally, collects and summarizes the knowledge of shaft,gear,sleave, and a sample with ladder—shaft is shown in order to verify the correction of theory research.

首先，本文介绍CBR技术的基础理论，并重点研究典型零件案例的表示、检索、修改等功能；其次，以零件设计编号为案例编号实现对案例的几何与非几何信息的集成，并实现了三维实体模型在Pro／E环境下的参数化修改功能；再次，从系统辅助设计功能要求出发，提出将基于规则的知识库嵌入到系统内部，用人工智能语言CLIPS建立零件设计知识库；最后，对轴类、齿轮类、盘套类零件案例知识进行收集、总结，并通过阶梯轴设计实例验证了理论研究的正确性。

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.
