In this situation, the books will gradually become the access to and the main way to increase my knowledge, and the library would naturally occupy in people's lives in a certain location, how to scientifically manage the library is not only related to the convenience of the reader to seek knowledge level is also related to library development, therefore, develop a comprehensive library management system will become essential, and this paper describes the environment in the Visual Basic6.0 adoption of the "top-down master plan, bottom-up application of development "strategy of development of the detailed process of this system is proposed to achieve the library information management, the basic objective of sharing resources, thus promoting the pace towards the digital library and described the system architecture design and functional design, from the warehouse of books Registration to the query view, from the library card issued to the lending of books, forming an overall automated management model, from the perspective of software engineering, scientific and rigorous exposition.

在这种形势下，书籍就渐渐地成为人们获取并增长知识的主要途径，而图书馆就自然而然地在人们的生活中占据了一定的位置，如何科学地管理图书馆不但关系到读者求知的方便程度，也关系到图书馆的发展，因此，开发一套完善的图书馆管理系统就成不可少了，本文介绍了在Visual Basic6.0环境下采用"自上而下地总体规划，自下而上地应用开发"的策略开发本系统的详细过程，提出实现图书馆信息管理、资源共享的基本目标，从而推动迈向数字化图书馆的步伐，并阐述系统结构设计和功能设计，从图书的入库登记到查询浏览，从借书证发放到图书的借阅，形成了一个整体自动化管理模式，从软件工程的角度进行了科学而严谨的阐述。

Actually, I saw there has been the result when the reader's query.

其实，我看到读者的提问时就已经有了答案。

The model of the thesis s forecasting method is synthetical use of experience model method and mine-reserach information adding power model method of mineral resources assessment based on GIS. It use several kinds of analysis means for multi-sources data. Firstly the gold-research prospective domains of this area are forecasted through the spatial query and ana-lysis by means of GIS,based on geological and mineral information of thearea, synthesizing geochemistry anomaly information. Gridding inserting value transforms geochemistry data of sampling point of the south of Acixiarega from scattering data to grid data by means of the development of Delphi and Mapobjects, using distance reciprocal inserting value method. After deposit orientation analyse and spatial overlapping analysis by means of CIS, the gold-research prospective domains of the area are forecasted.

本文所建立的预测方法模型是基于GIS矿产资源评价方法的经验模型法及找矿信息加权模型法的综合使用，对多源数据采用多种分析手段，先以研究区1：5万区域地质资料和矿产资料为基础，综合地球化学异常资料，通过Mapgis的空间检索与分析，做出全区成矿有利区分布图；而阿次夏热嘎南部地区离散的采样点的地球化学数据，是采用面向对象编程语言Dephi与GIS控件Mapobjects为开发工具，运用距离倒数插值法进行插值网格化，从而将离散的数据转换为栅格型数据，矿床定位分析、GIS空间迭加分析，预测出该地区成矿有利区。
