Firstly,the classification of probability rule is analyzed on the base of classic rough set concepts and extended to the equal relation of set in the indefinite system,namely,the upper and lower approximation space of research set is expressed in the form of conditional probability;then,according to the measure of probability rule,the attributes reduction is carried out and the classification rule is extracted by using the related parameters of condition attributes' impend precision from the angle of conditional probability;Finally,the related simulation test result is given and the result shows the classification rules with probability measures is more rational.

首先在经典粗糙集概念的基础上分析概率规则的分类，并将其推广到不确定系统的集合等价关系中，即用条件概率的形式表示研究集合的上下近似空间；然后根据概率规则的测度从条件概率的角度利用条件属性的逼近精度的相关参数进行属性集的约简进而提取分类规则；最后给出了相关的仿真实验结果，结果表明带有概率测度的分类规则更合理。

在分类部分，我们提出具有学习能力的混合型分类树，针对离子植入机里正在运作晶圆的配方进行分类，所得到的k-交叠相互验证错误率则用来作为分类结果的准确性。

Experiment result manifested that the parallel method has higher classification accuracy level than single decision tree, and it optimizes classification rules while keeping up good interpretability for classification results.

实验结果表明，该并行分类方法比单个决策树具有更高的分类精度，并在保持分类结果良好可解释性的基础上优化了分类规则。

Firstly, it studies the definition of implication and its classification, basing on this, deeply analyzes the relations between implication and the connective "if, then" universally used in our ordinary life. Then the article points out that implication is logical abstract to the connective "If, then" used in the natural language. However, because of different understanding and mastering to it, implication may have different classification, it can't be given a right definition. We must master it by all kinds of concrete implications. According to different criterion, implication has different categories. This article mainly discusses its classification from two sides: Ancient Greece and Medieval's and metalogic's.

首先，论文简要地考察了蕴涵概念的界定，指出蕴涵是对自然语言中连接词"如果，则"的逻辑抽象，而对它的意义的不同理解和把握，则可以有不同种类的蕴涵，不能笼而统之地对蕴涵下一定义，只有通过各种具体蕴涵去掌握有关蕴涵的理论；依据不同的分类标准，蕴涵可以有不同的类型，本文主要讨论古希腊及中世纪对蕴涵所作的分类及从记号学这一元逻辑的角度出发对蕴涵作的分类。

On the basis of the geological engineering conditions and rock mass quality classification, the change of wave speed of rock mass is used to analyze systematically the control of dissolution of calcareous sandstone over rock mass quality. The modificatory standard of rock mass quality classification was bring and the system of rock mass quality classification in the hydroelectric station.

论文在坝址区工程地质条件评价及岩体质量分级的基础上，利用岩体弹性波速的变化，深入研究了钙质砂岩溶蚀对岩体质量的控制作用，提出初步的岩体质量分级修正标准，得到坝区的岩体质量分级体系。

The four aspects are mainly optimized in this thesis: ABC classification is combined with fuzzy evaluation, which is applied in the inventory classification of automotive parts, and a right model is established for the classification management; the stock is controlled with order point and multistage programming and the flow charts are designed for reducing the inventory cost and assuring the smooth produ

论文主要从四个方面开展优化工作：将ABC分类法与模糊评判法结合，应用到汽车零部件库存分类中，建立合理的库存分类模型，实现货物的分类管理；应用订货点法和多阶段规划法进行库存量的控制，设计方法流程图，实现降低库存成本、保证生产流畅通的目的；以精益管理思想为指导原则建立全新的仓储作业流程，以此提高管理的信息化水平，提高工作效率；应用储位编码方法对货位进行编码，在作业流程中添加分配库位模块，实现货物智能存取功能。

In fact, combined classification is not only a trend in pattern recognition field, but an effective method for sure that has been proved. Based on these problems, multiple features of the nephogram data have been extracted in this paper, and according to the theory of information fusion, a classification method of multiple features of nephogram has been constructed. Recurring to the idea of information fusion, the performance of classification has been remarkably enhanced.

另外，针对目前卫星云图分类研究大多集中于利用单一特征集结合分类器进行云图分类，从而忽略了各特征相结合所具有的分类潜能问题，本文提出了一种卫星云图多特征融合分类方法，借助于信息融合的思想，使得分类器的性能得到明显的提升。

The result shows that the requirements and testing methods for flammability of building materials are similar between the United State and Canada, and they mainly are engaged in the test of combustibility and flame spread. In European Union, a new classification system for flammability of building materials was implemented in 2001, which includes two systems; one is for floor coverings and the other for all other building units. In Japan, the interior materials are classified into non-combustible, quasi noncombustible and fire-retardant materials according to Cone Calorimeter method (ISO 5660). China has established a non-combustible test, a three-class classification system for combustible wall and ceiling interior finishing materials and a two-class classification system for combustible floor coverings.

通过研究认为：美国和加拿大对建筑材料燃烧性能的要求和试验方法基本相似，他们主要针对材料的燃烧性、火焰传播进行检测；欧盟于2001年颁布了新的燃烧性分级体系，该分级体系包括专门针对铺地材料部分和针对其他所有建筑构件材料和产品部门；日本采用锥形量热计法(ISO 5660)将内装饰材料分为不燃、准不燃和阻燃材料3个等级；我国对建筑材料的试验方法包括不燃性试验方法、墙和天花板内装饰材料的三级分级体系和铺地材料两级分级体系。

"Second Life is remarkably easy to work with, and is very popular,"

"第二次生命是显着容易的工作，并且很受欢迎，"

For example, we usually assume that materials are homogeneous and isotropic and free of internal defects or flaws.

为了得到适合有限元分析的模型，我们必须经过如图2所示的简化步骤。
