| | This paper will brief you on establishment of one kind of GIS system-PURSIS (Peking University Remote Sensing Information System) on microcomputer, IBM PC/XT, AT, and simply explain its basic characters, functions for data processing, digital data formats, picture data base system and expert system. Based on the idea of modular programming, we should organically combine many thematic GIS, each of them becoming a subsystem. The data collected and stored by GIS can be shared b'y any subsystem. The main system... | | 本文介绍了北京大学遥感技术应用研究所(国家遥感中心技术培训部)于1988年4月推出的地理信息系统通用软件PURSIS的设计原理与方法。由于它是在IBMPC/XT,AT及系列兼容机上研制的,因此便于推广使用。为了克服微机在速度和容量上的种种限制,PURSIS系统采用了一些较复杂的技术手段,使得与其它系统相比,具有如下明显特点:(1)利用软件技术,为图形的输入和编辑创立了一个良好的交互式工作环境,使用户能方便地输入和修改各种地图。(2)采用压缩编码技术存贮图形和图像数据,从而大大减轻了微机系统的空间负担。(3)设计了高效率的数据格式转换算法,使矢量数据能快速转换为网格数据。(4)设计了COLOR 136软件,将廉价的COLOR-400卡支持的16种颜色扩充为136种颜色,成功地解决了专题图件的显示问题。(5)解决了图形数据和属性数据的联合操作问题,使用户能在图的逻辑概念上进行多种操作。此外,数字地形模型和其它数据在操作时的联系甚为紧密。(6)提供了一些常用的应用工具,如专家权重、叠加分类、专家命题等模型。使用户在这些模型支持下解决一些各自的专业问题。(7... | | 文摘来源 | | Glucose Oxidase is the key enzyme instrument of blood-glucose determination. This article studied the techonology of ferment production glucose oxidase and its method of compounding enzymic reagent kit, of which we used penicillium notatum AS3. 3871 strain. The developed production conformed to the technical index of clinical laboratory center of the Health Ministry of P. R. China.
