According to the professional characteristics of economy and management and social demands of economy and management talents this article put for ward a new experimental teaching system including four modules based on ability cultivation.

针对经管类专业教学特点和社会对经管类人才要求，提出了一种基于能力培养的4模块的经管类新型实验教学体系结构，并对体系结构内容进行了讨论，总结了新型实验教学体系特色。

Any class with an abstract method is automatically abstract itself, and must be declared as such.

任何有抽象方法的类自动变成抽象类，而且必须被声明为抽象类。

Protected受保护:members of class are accessiable from within same class or from members or from members of their derived class.

类的受保护成员比类的私有成员多一条被访问通路。它可以被该类的衍生类的成员所访问。

The second-class accommodation on a train or ship is the ordinary accommodation, which is cheaper and less comfortable than the first-class accommodation.

In this master thesis, we mainly discuss the adjacent vertex- distinguishing total chromatic numbers of some special graphs and prove that Zhang"s conjecture holds for these graphs. Then we get the adjacent vertex-distinguishing total chromatic numbers of the Halin Graphs. Moreover, we investigate the Generalized Petersen Graphs, prove that some classes of positive integers can"t structure the Generalized Petersen Graphs and get the result that the adjacent vertex-distinguishing total chromatic number is 5. Finally, based on the number and the parity of circles contained by the graph, we get the adjacent vertex-distinguishing total chromatic number of two classes of graphs.

本学位论文首先主要针对几个特殊图类讨论其邻点可区别全色数，验证了其满足图的邻点可区别全色数的猜想；再证明了非轮的Halin图的邻点可区别全色数；接着研究的是广义Petersen图，讨论了不能构成广义Petersen图的几类正整数，并证明了该图的邻点可区别全色数等于5；最后，根据图所含圈的个数及其奇偶性得到了两类图的邻点可区别全色数。

And abstract nouns were categoried as: nominal abstract, verbal abstract and adjectival abstract nouns.

抽象名词又分为名类抽象名词、动类抽象名词和形类抽象名词。

At the same time, we prove that the best linear unbiased prediction of a linear predictable variable Qy and the best linear unbiased prediction βn=(X"sV-1Xs)-1 X"sVs-1ys of regression coefficients of the finite populations βn=(X"V-1X)-1X"V-1y are admissible under matrix loss function and in the class of the linear predictions and the class that contains all predictions, and under quadratic loss function in the class of the linear predictions.

在线性预测类和一切预测类中是可容许预测，而在二次损失函数下其在线性预测类中是可容许预测。

The dendrogram shoe that the 55 materials were divided into five class at the line L_1,the agnate No.4 was a class and matriline longwangmao was a class,the other three agnate and hybrids were regular cluster,only agnate No.1 and P6-N-4、P6-N-7、P6-N-8 etc.14 hybrids were cluster,show partial male type.

另由树状图得知在L_1处可将55份供试材料分成5大类，除父本4号与母本龙王帽各自成一类外，其余3个父本与杂交苗有规律的聚类在一起，但只有父本1号与P6-N-4、P6-N-7、P6-N-8等14个杂交苗聚类到了一起，表现出偏父型。

Chapter 4 presents five design criteria of S-boxes of block ciphers, develops a method of constructing large S-box by use of algebraic group operation, proves the balance property of these large S-box, tests the strict avalanche and independence of avalanche variables properties of S-boxes in NEA cipher, analyses the nonlinearity and best linear approximation of the S-box, and finally defines the differential of input/output of S-boxes of this cipher and analyses the distribution of them.

第二部分即第三章，提出了一种新的分组密码类NEA(NEA-4A，NEA-8A，NEA-4B，NEA-8B)，完整地描述了该密码类的加解密过程和密钥协议；证明了NEA-4B和NEA-8B的完全对合性和没有不动点的性质；分析了该密码类的安全特征；具体地介绍了实现该类密码的途径；给出了NEA-4A的计算机C语言程序和样本数据。

Two-phase-learning is adopted. The strongpoint is that intuitionistic knowledge can be used to control the segmentation by using input-weight and distant-weight. Examples prove that segmentation using SOFM network is right and efficient. Surface fitting is an absolutely necessarily process in REGM. Surface fitting includes algebraic and parametric surface fitting. Algebraic surface fitting has not extra requirement for data distribute format and boundary shape.

第三种方法把人工智能用于反向工程的数据分区，因为数据分区的实质是相似特征的聚类，而神经网络可以实现自组织特征映射，在本论文中第一次把自组织特征映射神经网络用于多视图点云的数据分区，通过神经网络对数据点的坐标、法向量等几何特征进行聚类，并且运用了快速稳定的训练方法——两阶段训练算法，最重要的是，通过距离权值和输入权值可以把用户观察所得的直观知识加入聚类过程。

But we don't care about Battlegrounds.
