Fundamental solutions for half plane with an oblique edge crack

An elastic half plane with an oblique edge crack is considered in this paper. A pair of concentrated forces or point dislocations is assumed to act at an arbitrary point in the half plane. The half plane with an edge crack is first mapped into a unit circle by a rational mapping function so that the following analysis can be carried out on the mapped plane analytically. Then the complex stress functions are derived by separating the whole problem into two parts; one is the principal part corresponding to the infinite plane acted on by concentrated forces or dislocations, the other is the holomorphic part, which can be determined by making use of the property of regularity of complex stress functions. The stress intensity factors of the crack can be calculated with different inclined angles of the crack, and the displacement and stress components at an arbitrary position in the half plane can be expressed explicitly.     

小波变换在红外图象处理中的应用

小波变换近年来在图象处理中的应用日益受到人们的关注。小波变换可能同时在时间（或空间）和频率域对信号进行分析，是多分辨率分析的有力工具。本文介绍了小波变换在红外图象处理中的应用，例如红外／可见光图象的配准与融合，红外图象增强，红外图像中的微弱目标探测等。     

化学结构式的拓扑描述

化学结构式的拓扑描述,是化学信息计算机化的手段之一。这里系统地建立了一整套的连接表(三类:紧缩连接表、冗余连接表、和连接方阵),用来进行结构式中原子之间连接关系的拓扑描述,对分子结构进行数值化。同时,阐述了连接表唯一化的方法,并介绍了不同类型连接表之间的转换关系和还原为平面结构式图形的绘图程序。

Microbial degradation of di-n butyl phthalate

Microorganisms capable of degrading di-n-butyl phthalate (DBP) were isolated. The characteristics of DBP biodegradation by immobilized and free cells were investigated. The experimental results showed that the rate of DBP degradation of immobilized cells was higher than that of free cells.
