对DEBUG实用程序的一点改进──使DEBUG能跟踪“反跟踪软件”

作者提出对ＩＢＭＰＣ系列微机上ＤＥＢＵＧ实用程序的一种改进方法，即通过修改单步中断和断点中断的处理程序，使之能跟踪“反跟踪软件”，这对软件解密和病毒分析无疑是有用的。     

Discovering Frequent Subtrees from XML Data Using Neural Networks

By rapid progress of network and storage technologies, a huge amount of electronic data such as Web pages and XML has been available on Internet. In this paper, we study a data-mining problem of discovering frequent ordered sub-trees in a large collection of XML data, where both of the patterns and the data are modeled by labeled ordered trees. We present an efficient algorithm of Ordered Subtree Miner （OSTMiner） based on two- layer neural networks with Hebb rule, that computes all ordered sub-trees appearing in a collection of XML trees with frequent above a user-specified threshold using a special structure EM-tree. In this algo- rithm, EM-tree is used as an extended merging tree to supply scheme information for efficient pruning and mining frequent sub-trees. Experiments results showed that OSTMiner has good response time and scales well.

The Translatology Process of the Word''''Gaze''''in Chinese Context

With reference to the concept of'cultural studies'and certain modern theories in translation studies,this essay makes a general analysis of the translation and introduction of the'gaze'concept in China.On the basis of this analysis,it explores how this concept spread to China and why,this concept Was explained and rewritten through translation and interpretation in the course of the spread;and what responses and reflections we should bear during the process.     

液体分子自由程压力系数与温度系数研究

Ｊａｃｏｂｓｏｎ在Ｅｙｒｉｎｇ分子模型基础上提出了液体分子自由程理论．根据这个理论，液体分子自由程即分子表面之间的距离应为Ｌ＝２Ｖａ／Ｙ．本文在Ｊａｃｏｂｓｏｎ理论基础上，给出了液体分子自由程压力系数与温度系数两个参量，研究了部分烷烃、烯烃、醇、苯及其卤代物的自由程压力系数与温度系数．在以后的研究中，我们还发现这两个参量与分子力及液体声速系数有密切联系
