类化

We adopt denotational semantic approach to describing semantics of inheritance, instantiation, object creation, message passing and method call.

本文采用指称语义的方法描述了类的继承、实例化、对象生成、消息传递、方法调用的语义。

Third, the algebraic specifications are used in order to reveal the essentials of denotational semantics and to get more modularity and less complexity. Chapter 2 introduces the basic concepts and notations used in this dissertation.

三是采用代数规约的框架，这有助于揭示将语法作为多类基调代数的型构定义，将程序作为表达式的指称语义方法之实质思想，也有助于形式定义文本的模块化，降低描述复杂度。

Well the majority of the tourists nowadays prefer to travel in groups with t heir entertainment and sight seeing included in the package. Some tourists pref er personalize tours which provide the comfort of a guide to show them aroun d the scenic sights and make all the necessary arrangements for them. These more independent tourists may request tour services though their hotel or a loc al travel agency.

大多数的游客现在都喜欢选择那种将娱乐和观光活动全部包括在内的团体旅游方式，也有一些游客喜欢个体化的旅游方式，这类游客聘用一名导游带领他们游览景点，为他们做一切必要的安排，这些独立性更强的游客可以在所居住的旅馆或当地的旅行社要求得到个体旅游服务。

This article summarizes recent progress in hybrid electroluminescent materials and hybrid liquid crystals based on POSS,and self-assembly behavior of POSS derivatives.

本文综述了近几年来POSS基有机/无机杂化的电致发光材料、液晶材料和POSS衍生物的自组装行为的研究进展，指出这类材料由于制作方便和热力学性能优良，在未来高科技领域中必有宽广的应用前景。

It generalized the traditional k-means algorithm from the point of view of prototype selection. In detail, the kPC algorithm substituted hyperplanes for points used in k-means algorithm to be the prototypes and got these hyperplanes by minimizing the sum of the squared distances between each point and its closest hyperplane.

它从原型选择的角度推广了传统的k-均值算法，用超平面替代k-均值算法中的中心点来表示聚类原型，并通过最小化样本点到最近中心超平面平方距离之和来求取原型超平面。

His current research interests include: biochemical studies of metallothionein-like metal binding proteins and phytochelatins in plants; immobilised algal biotechnology; and conservation strategies for mangroves and their application in sewage treatment.

目前他致力於研究以下项目：类金属硫蛋白的金属结合蛋白的生物化学以及植物的鳌剂研究；固定化微藻的生物工艺学研究；研究保护红树林策略以及利用红树林进行废水处理。

ECMAScript does not contain proper classes such as those in C++, Smalltalk, or Java, but rather,supports constructors which create objects by executing code that allocates storage for the objects and initialises all or part of them by assigning initial values to their properties.

ECMAScript没有像C++，Smalltalk，或者java中那样规矩的类，可是它支持通过执行分配空间的代码来创建对象、并初始化对象所有或者一部分属性的构造器。

The constructor of this class will take a reference to the io_service object and use it when initialising the timer_ member.

这个类的构造函数使用一个io_service对象的引用来初始化 timer_ 成员变量。

Once you have instantiated a copy of this class, you can begin using it immediately.

一旦你实例化这个类的副本，您可以立即开始使用它。

Since it is a static class, it can never be instantiated and all of its members must be static.

由于它是一个静态类，它不能被实例化及其所有成员必须是静态的。

I this is at that time, the opinion with peacockish true girl is full of in a heart.

这就是当时的我，一个心中布满虚荣的女孩子真实的想法。
