查询词典 class function

Fully taken consideration of the features of the XML Schema, the structures of the logical UML class diagram are concise. Through a series of steps, the logical UML class diagram can be translated from the original conceptual UML class diagram, thereafter the XML Schema can be available in a one to one manner.

给出的逻辑层UML类图充分利用了XML Schema文档的嵌套结构特点，结构清晰简明，经过一系列的转换步骤，可以由概念层的UML类图生成逻辑层UML类图，并最终得到XML Schema设计。

This mangling is done without regard of the syntactic position of the identifier, so it can be used to define class-private instance and class variables, methods, as well as globals, and even to store instance variables private to this class on instances of other classes.

这种混淆不关心标识符的语法位置，所以可用来定义私有类实例和类变量、方法，以及全局变量，甚至于将其它类的实例保存为私有变量。

If a class has no , and teaching is meaningless to the development of the teacher or the students, or teaching has side effects, then teaching human being means teaching objects, so teaching is worse than no teaching; If a class is of no effect, then teaching means nothing; If efficiency can not be found , what is the difference between a class and a campaign in which you annihilate a maniple of enemy at the cost of a brigade? more a loss than gain; Without magnetism, like a sheet of loose sand, crystal will not come into being, full development will be out of the question, let alone sustainable development.

如果一堂课没有价值，教学对学生、对老师的发展没有意义或者造成负面的影响，那么教人等于教物，教小于不教；如果一堂课没有效果，那么教等于白教；如果一堂课没有效率，无异于战役中吃掉了敌人一个连，自己损失了一个旅，得不偿失；教学没有磁性，好比一盘散沙，没有结晶，谈不上充分发展，更不用说可持续发展了。

The method optimizes the features according to the class separable criterion of margin of within-class and among-class distance and selects the optimized feature vector combination based on four kinds of features,such as gray histogram feature,wavelet transform feature,gray level co-occurrence matrix feature and moment invariants feature,with 26 dimension feature vectors in all.

针对冷轧板带材常见表面缺陷图像识别的特点，提出了板带材表面缺陷多特征优化组合方法，该方法以直方图统计特征、小波变换特征、灰度共生矩阵特征、不变矩特征等4类特征共26维特征向量为基础，依据类间类内距离差的类别可分离性判据对特征进行优化，选出最优特征向量组合。

For the monotone class of filters, the robust stability test is similar to that of Kharitonov theorem, which only needs to test four extreme polynomials of the class. However, for the non-monotone class of discrete systems, the test must examine possible combinations of all extreme polynomials.

单调系统簇的稳定性检验与Kharitonov定理的检验类似，只需检验集合中的四个端点或复多项式，而非单调系统需检验所有可能的端点复多项式的组合。

As a student union officer, I organized collage magazine show, paper competition; As a class committee member, I organized Mid-autumn Festival trip, New Year party; As the commissary in charge of studies, I moot a case to practice court debate, in charge of communication between professors and students; As a class member, I took part in debating competition and won the first prize; Not only did I win the scholarship but also I was awarded "the excellent graduate","the best Party member","the excellent student council leader" and "the excellent class leader".

作为一名学生会干事，我组织了校刊杂志展示，征文比赛；作为一名班委员会成员，我组织了中秋节之旅，新年联欢；作为学习委员，我模拟一个案件进行法庭辩论，负责沟通教授和学生间的信息；作为一名班级成员，我参加了辩论比赛并获得了一等奖；我不仅赢得的奖学金，而且被授予"优秀毕业生"，"优秀共产党员"，"优秀学生会干部"和"优秀干部"的荣誉。

For example, if we extend class Animal to create class Tortoise (which might respond to a move message by crawling one inch), we need to write only the Tortoise class and the part of the simulation that instantiates a Tortoise object.

例如，如果我们扩展类动物，创造一流的龟（这可能响应消息通过抓取移动1英寸），我们只需要编写乌龟类和模拟的实例化一个龟对象的一部分。

Among others, every URI that is used as a class name must be explicitly asserted to be of type owl:Class, every individual must be asserted to belong to at least one class (even if only owl: Thing), the URI 's used for classes, properties and individuals must be mutually disjoint.

而选择 OWL DL 或是 OWL Full 主要取决於使用者应用的范围是否需要 RDF 的元件模组化（meta-modeling）机制，（例如：定义类别的类别或是为替类别附加新的属性）。

In 42 ACME-arcA-positive isolates, 8 isolates harbored SCCmec V, 8 isolates harbored class C1 mec complex and ccrAB_, 22 isolates harboring class C1 mec complex and 4 isolates harboring class C2 mec complex were negative for all known ccr allotypes.

本研究在ACME-arcA基因阳性菌株中发现整合酶基因ccr的一种新亚型ccrAB_(SHP.42株ACME-arcA基因阳性菌株，8株携带V型SCCmec，8株携带C1型mec基因复合体和ccrAB_，剩余26株携带C型mec基因复合体和未分型ccr。

Firstly, the eigenvalue problem of a class of second order elliptic equation with critical potential and indefinite weights is considered. Then, using critical point theory, Trudinger-Moser inequality and the properties of the first eigenvalue, we prove the existence of a nontrivial solution for a class of nonlinear elliptic with critical potentialand indefinite weights in R~2. Secondly, we prove the existence of nontrivial solutions for a class of subcritical and critical elliptic systems with indefinite part in R~2 byusing a generalized linking theorem, Trudinger-Moser inequality and concentration-compactness principle.5. The existence of at least three weak solutions for discrete boundary value problem is established by using a three critical point theorem introduced by Ricceri.

首先，讨论了R~2中一类带不定权且含临界位势的二阶椭圆型方程的特征值问题，并借此特征值问题的第一特征值性质，利用山路引理及Trudinger-Moser不等式，证明了R~2中一类带不定权且含临界位势的非线性椭圆型方程非平凡解的存在性；其次，利用广义环绕定理，Trudinger-Moser不等式及集中列紧原理，得到了R~2上一类具有强不定部分的半线性椭圆型方程组在非线性项分别为次临界增长和临界增长情形下非平凡解的存在性。

A strange and mysterious deep sea creature.
