The purpose of this article to discuss realization of journal information resources sharing and develop ing and using. It is very effective that building a journal union catalog database retrieval system undernet environment, the system can realize journal information resources union building, sharing in mo re range.

旨在探讨期刊信息资源共享和开发利用的实现途径，认为建立期刊联合目录数据库，并将WWW 技术与数据库技术紧密结合，开发基于W eb 平台的期刊数据库应用系统，则是在更大范围内实现期刊资源共知、共享、开发利用的基础和行之有效的途径。

In this thesis, an improved method is proposed to overcome the problem that the circular color histogram method does not take the spatial information of colors into account , combines spatial distribution information with image color features. The presented method adopt color space which has the visual uniform , three components carries on no laddered quantification, three components weighting summation composes the row of the circular color histogram construction, and improves retrieval quality, while rotation and translation invariance of color histogram are kept.

针对颜色直方图对图像的空间信息表现不够的问题，本文提出并实现了环形颜色直方图的改进方法，将图像颜色特征和颜色的空间分布信息相结合，采用具有视觉一致性的颜色空间，并把各通道分别进行非等间隔量化，采用各通道向量加权的形式把各通道组合为一个特征向量，提高了检索质量，并保持了原有算法的有效性和旋转不变性。
