The mean of jdbc is normative on programming , clear on interface , high efficient on researching . so the database of the cement kiln simulation is managed by use of relational database and jdbc ( java database connection ) programming technology 根据java语言具有很强的网络编程能力及很多优点， jdbc方式编程规范、接口清晰、开发效率高的特点，选定关系型数据库和jdbc编程技术对水泥窑仿真系统数据库进行管理。
This article is useful to developers who are new to java native interface programming and want to test their jni programming skills on linux for power distributions , such as red hat enterprise linux 3 and suse linux enterprise linux v9 对那些刚接触java本地接口编程，并且想要在用于power的linux发行版本（比如red hat enterprise linux 3和suse linux enterprise linux v9 ）上检验其jni编程能力的开发者来说，本文会有所帮助。
Based on the investigation and g1s software of arc view , an environmental geochemistry gis of the shallow groundwater in city zone and close suburb of beijing is developed . the system can do many jobs for the environmental data of groundwater such as collection , storage , management , analysis and calculation , which shows a powerful function in spatial search , analysis , display and programing . in the two years of 2000 and 2001 本文在详细调查北京城近郊区浅层地下水污染情况的基础上，根据需要，对地理信息系统软件arcviewgis3 . 2a进行了二次开发，建立了北京城近郊区浅层地下水环境地球化学gis系统，实现了对地下水环境数据的采集、存储、管理、分析、计算和图形显示等多种功能，展示了强大的空间查询、分析和编程能力。
At the same time , the java mightness network programmable and the interface technology to vrml are discussed deeply , which realize the control action to vrml , by anatomy of event in , eventout , script and so on , in particular , according to the demand of network learning to participate the simulate experiment , the eai is analysed in detailed as well 同时，本文比较深入地探讨了如何利用java的强大网络编程能力及其和vrml的接口技术，来实现对vrml行为进行控制的机制，对eventln 、 eventout及script节点等进行了剖析；另外，针对网络学习者如何参与仿真实验(交互)的要求，对eai (外部创作接口)也作了比较详细的分析。
Abstract : a kind of microcomputer control system for teaching is presented . this system is composed of 89c51 microcomputer and its periphery circuit . many kinds of experiments of software and hardware can be done by this system , and the students can be trained in both programming and operational ability 文摘:介绍了一种用于单片机实验的多功能教学控制系统.该控制系统以89c51单片机为核心，进行了串、并行口的扩展和外围电路的设计，可进行单片机教学的多种软、硬件实验，这样既可以锻炼学生的编程能力，又有助于提高学生的操作能力
