归纳定义

First it concludes elementary methods for product modeling such as feature recognition, feature-based design and feature mapping. Then it probes into the mechanism of constraint-based feature parametric modeling, representation of feature parametric model and methods for solving constraint in details. At the end it proposes a feature-based modeling system that makes good use of resources and synthesizes many feature modeling methods, and analyses the development of prototype system oriented to actual application.

接著我们归纳低维度的特性，并藉由定义出一组方程式-标准n维空间分割系统-来推广这些特性到一般的$n$维度空间中。

Then the informationtheoretic entropy measure and Laplace error rate evaluation functions are applied to the path search in extension matrix, and a heuristic algorithm ECA based on entropy is given The time complexity of ECA is also analyzed Finally, ECA is applied to several real-world domains such as sleep examples and handwritten digit recognition, and the experimental results show that ECA can produce more simple and efficient rules.

针对实际应用领域中的噪音问题，从统计学的角度，对扩张矩阵理论的定义加以扩充，放宽关于规则的概念描述限制：在训练例子集上归纳得到的概念，不一定完全正确分类训练例子集，而是以较大的正确概率分类训练集，并对新的例子有较好的预测能力。

In this part, there is a reasonable explanation to the definition of the reiterative by way of contrast,summary,accounting etc,and the writer has studied reiterative"s category, parts of speech, the function and so on, also made a research of reiterative"s features in HeLin YuLu systematically in an all-round way.

在这一部分对叠音词的定义作了合理的阐释，运用比较、归纳、统计等方法，分析了它的类别、词性、作用等，全面系统地研究了叠音词在《鹤林玉露》中的特点。

It establishes the uniform, singular and two kinds of normal distributions models of diffusion layer statistical distribution, the result shows that the more singular the statistical distribution of the cathode gas diffusion layer porosity is, the better the cell performance is, and the more uniform, the worse the cell performance is.

最后，从热力学的角度分析了燃料电池过程的能量转化形式，反应的焓变主要转变成电能和热能两种能量形式；归纳了燃料电池电化学的一些基本理论模型及简单的推导过程；描述了燃料电池效率的一些不同的定义以及对采用热电联供的方式提高燃料电池能量利用效率的分析。

An inductive learning method for classification based on information theory is proposed, which is a maximum contribution classification method according to the theory of channel transmission in information theory, the definition contribution is developed based on probability distribution of classified space, probability transfer matrices of classified space and feature space and mutual information, then entities is classified by the maximum contribution method.

提出了一种基于信息论的归纳分类学习算法－最大贡献分类算法。该算法根据信息论中信道传输的理论，把类别空间和各特征空间的概率转移矩阵以及互信息结合起来，定义了贡献的概念，从而得出了对给定的观测值，用它的最大贡献作为对实体进行分类的规则。
