Through selectors and dynamic linkage the same function name will take different actions for different classes . such a function is called polymorphic 通过选择器动态链接不同类的相同的函数名，但会带来不同的结果。这样的函数被称作动态函数。
Programmer work with database as with abstract indexed collection of objects of different classes using object identifiers as index in this collection 程序员可把此数据库看做属于不同类的对象的带索引的抽象集合，在此集合中，对象标示符就是其索引。
These case studies will involve a wide variety of products , including flowers , computer software , power tools , watches , and even contact lenses for chickens ( seriously ) 这些案例会包括很多不同类的产品，比如花、电脑软件、电力工具、手表，甚至是小鸡用的隐形眼镜。
To achieve the loosely - coupled view of information sources from applications , information management in soa accesses and aggregates heterogeneous data and content sources this capability is known as 为了从应用程序中得到信息源的松耦合视图， soa中的信息管理访问并且聚合了不同类的数据和内容源（这种性能称为
On this classification base , thesis bring advance a route mean which hold many different forwarding information tables in single router , each classification data is forwarded according to different forwarding information table 在分类的基础上提出通过建立多个路由转发表，让不同类的数据通过各自合适的转发路径进行传输的方案。
He speculated that it was probably unlikely that they could all have arisen spontaneously as separate species and thought that it was more probable that they had evolved from a mainland species of finch , possibly from ecuador 他觉得这些不同类的雀科鸟类不太可能是作为独立的物种同时形成的，它们很可能是来源于厄瓜多尔的同一个祖先。
Clustering is the process of grouping the data into classes or clusters so that objects within the same cluster have high similarity in comparison to one another , but are very dissimilar to objects in other clusters 所谓聚类,是将一个数据单位的集合(数据源)分割成几个称为类或类别的子集,每个类内的对象之间是相似的,但不同类的对象间区别相对较大。
Clustering is the process of grouping the data into classes or clusters so that objects within the same cluster have high similarity in comparison to one another , but are very dissimilar to objects in other clusters . dissimilarities are assessed base on the attribute values describing the objects 所谓聚类，是将一个数据单位的集合(数据源)分割成几个称为类或类别的子集，每个类内的对象之间是相似的，但不同类的对象间区别相对较大。
Algorithms to combine the neural networks classifiers based on dempster - shafer theory and two kinds of fuzzy integral ( sugeno and choquet integral ) respectively are proposed . the influences of the fact that every classifier has different classification ability for different class are all considered in these two kinds of algorithms 提出了分别基于dempster - shafer组合公式和两类模糊积分( sugeno积分和choquet积分)进行多个神经网络分类器组合的算法，这两种算法都考虑了每个分类器对不同类的识别能力的不同这一经验知识。
Beside routine clinical work , the new machine will be used for the latest research projects undertaken by the division of cardiology . these involve the assessment of cardiac function in patients with a variety of cardiac disorders , the detection of abnormal motion due to shortage of oxygen supply to the heart muscle using a sophisticated colour doppler based technique , and also research into arterial diseases and the effect of various treatments 这部仪器可广泛应用于需求量激增的常规临床检查，包括测量颈动脉及其它动脉壁的厚度，有效诊断动脉血管病，亦可用于心脏科研究工作计划，如测量不同类的心脏病患者的各种心脏功能、诊断因心肌缺氧供应而引致的不正常心肌活动，同时又可研究动脉血管病及各种治疗的效果。
