在改进

Firstly, we select features by using CHI distribution. Secondly, we cluster the selected features by using an improved method which based on density. In virtue of the sort distribution information, we reduce the number of features twice and the information lost few. Lastly, based on the sort of texts, we use the distributing of probability to express text with matrix. By using matrix norm, we realized the text categorization.

首先通过分布对特征项进行选择，然后使用一种改进的基于密度聚类方法对选择后的特征项进行聚类，借助类别分布信息，在尽量减少信息缺失的前提下先后两次对文本特征维数进行了压缩；在基于类别概率分布的模式下实现文本的矩阵表示，借助矩阵理论进行文本分类。

The results showed that fishes of 11 orders, 18 families, and 46 species were represented in Changshu section of the Yangtze river. After the season, the total catch per unit effort increased sharply in the section; the dominant species were mainly commercial fishes such as Coilia ectenes, Mugil cephalus and Parabramis pekinensis and the annual change of dominant species was not obvious. The CPUE of Coilia ectenes had risen up and the trend of resource deterioration had been kept within limits. The caught rate of pintsized and juvenile fish rose markedly. The Margalef's index and Wilhm's index had an evident tendency of rising, while McNaughton's index and Pielou's index waved slightly.

研究结果表明：4~6月间常熟江段出现的鱼、虾、蟹类渔获物共有11目、18科、46种；春禁后，该江段总CPUE显著增加；优势种更替不明显，历年以刀鲚、鲻鱼、长春鳊等经济鱼类为主；刀鲚CPUE有所回升，资源衰退受到遏制；小型鱼类、幼鱼在渔获物中的比例明显上升； Margalef物种丰富度指数、Wilhm改进指数呈明显上升趋势，均匀度指数J′、优势度数Dw在窄幅范围波动。

In this article, we use the Genetic Algorithms to solve the problem of optimal path of merchandize distribution and realize it in the computer with Language C.

Even if some failures can be attributed to the Bush administration, the most important reasons for Katrina's deadliness may lie in decisions that predate the current president, from Jean Baptiste le Moyne de Bienville's decision to found the city in its precarious location, in 1718, to the more recent "improvements" in the area's maritime navigability that have damaged south-eastern Louisiana's wetlands.

虽然一些因素可以归结为布什政府，但卡纳里亚致命袭击最重要的原因是在现任总统以前造成的，归根于Jean Baptiste le Moyne de Bienville在1718年的决定：建城于这个不稳定不安全的地区，而最近的海上可航行性的"改进"则破坏了路易斯安那州东南部的沼泽地区。

The optimal models and algorithms for making up pairs and non-pairs locomotive turn-around diagram are given out. Specially, a more efficient way to consider both the optimum and the equilibrium of this problem is also presented as follows: at first formulate the network flow model of this problem and solve it by the method of the minimal cost flow and then use the labeling method to readjust the solution.
