利用Llibre的代数不变式理论，首先由二元二次和二元四次多项式的分类结果，对一次和三次齐次多项式微分系统进行代数分类，同时补充了已有结果中出现的漏洞；其次，由称共变张量空间的性质，对缺二次项的三次微分系统在保证轨线走向不变的前提下进行代数分类，使分类后同类系统的示性多项式有相同零点；最后通过讨论一类简单系统的有界性说明了分类的方便方处。

This paper proposed a new algorithm for eyes detection in the images. First, in a known face image, the homomorphic filter was used to enhance the contrast of the image and the iterative thresh choosing algorithm changed the gray images into binary ones. According to certain priori knowledge, it could get the candidate field of the eyes.

Because the characteristic is combining explosive, it is advised that using Binary SLNN to solve the problem. In order to test the liability of the results, this study will use random researching method in comparison with Weighted Hungarian Method. It is found that the testing result of SLNN is superior to Weighted Hungarian Method in solution-effect and random searching is the worst one.

由於问题具组合爆炸的特性，故本文拟以自我学习神经网路解多目标指派问题，另为使解答有比较之依据，在此与随机合法解及加权匈牙利法的解答作比较；经测试，在解答品质及稳定性方面，以自我学习神经网路表现最佳，加权匈牙利法次之，随机合法解效果最差。

According to the characteristic of hybridize and sudden change of binary coding chromosome in classical genetic algorithm,this paper defines the rule of hybridize and sudden change of continuous variables .

根据传统遗传算法中对于二进制编码染色体的杂交和突变的特点，定义了连续变量的杂交、突变规则。

In this paper, with 2-oxo-propionic acid salicyloyl hydrazone as a ligand, one calcium complex, three copper complexes and thirteen rare earth(RE=La, Ce, Pr, Nd, Sm, Eu. Gd, Tb, Dy, Er, Tin, Yb and Lu) complexes have been synthesized. The crystals of four complexes were obtained, and the crystal structures were determined by single crystal X ray diffraction. One of the crystals is calcium complex, the other are binary and trinary complexes of copper.

本文选用2-羰基丙酸水杨酰腙作为配体，在水中分别与钙、铜、稀土(RE=La、Ce、Pr、Nd、Sm、Eu、Gd、Tb、Dy、Er、Tm、Yb和Lu)的盐反应，共制得了17种未见文献报道的配合物，另外还培养了2-羰基丙酸水杨酰腙、咪唑与铜、钙的二元及三元配合物的四种单晶，对La-Gd的稀土的配合物进行了溶解热的测定，并用Gauss-98软件包对铜的配合物进行了有关量化计算。

To overcome the false result with piecewise constant regions produced by the binary zero-crossing decision process, a hyperbolic tangent function is used to substitute the symbol function, governing softly the varieties of gray levels of pixels beside the zero-crossing of edges.

为了克服二值的零交叉决策过程导致的虚假的分片常数图像，利用双曲正切函数代替符号函数，柔和地控制边缘的零交叉点两侧像素的灰度值变化。

Constructed by standard binary classes support vector machine, present multiclass SVMs are usually very slow to be trained. When a large number of categories of data are to be classified, the training work could be very difficult. By extending the hypersphere one-class SVM to a hypersphere multiclass SVM, we build a fast training classifier HSOC-SVM. Its training speed is higher than that of the present multiclass classifiers, because each category data trains only one HSOC-SVM.

目前的多类分类器大多是经二分类器组合而成的，存在训练速度较慢的问题，在分类类别多的时候，会遇到很大困难，超球体多类支持向量机将超球体单类支持向量机扩展到多类问题，由于每类样本只参与一个超球体支持向量机的训练，因此，这是一种直接多类分类器，训练效率明显提高。
