此为一款基于J2ME的手机游戏，《重装机兵》源代码，本源码并未在手机上测试，可以编译成功。这款游戏基本实现了必须的所有功能，如碰撞探测、地图转换、NPC对话、事件处理,、横版回合制战斗系统等，并根据原游戏的特色加入了人、车两战斗系统，在玩的过程中，你可以用方向键控制人物行走；回车键弹出游戏菜单，"1"键进行命令取消。-This is a J2ME-based mobile phone games, the " capacity of soldiers," the source code, the source has not been tested on cell phone, you can compile successfully. The basic implementation of the Games must be all the features such as collision detection, map conversion, NPC dialogue, handle case, cross-version of turn-based combat system, and in accordance with the characteristics of the original game by adding the person, the two fighting vehicle system, playing process, you can use the arrow keys to control the character walk Games Enter the pop-up menu, " 1 " key to cancel the order.

虽然Windows下可视化开发工具如VC、Delphi、C＋＋ Builder等都有专用的定时器控件Timer，而且使用很方便，可以实现一定的定时功能，但最小计时精度仅为55ms，且定时器消息在多任务操作系统中的优先级很低，不能得到及时响应，往往不能满足实时控制环境下的应用。不过Microsoft公司在Win32 API函数库中已经为用户提供了一组用于高精度计时的底层函数，如果用户使用得当，计时精度可到1ms。这个计时精度、对于一般的实时系统控制完全可以满足要求。现将由C＋＋ Builder 4.0提供的重新封装后的一组与时间相关的主要接口函数（函数名、参数、功能与Win32 API基本相同）说明如下： -visual development tools such as Visual C++, Delphi, C++ Builder and others all have dedicated Timer timer control, but it is convenient. can achieve a timing function, but only the minimum time of 55 ms accuracy. Timer news and multi-task operating system in the low priority that is not to respond in a timely manner, often fail to meet the real-time control environment applications. However, Microsoft Corporation in the Win32 API function has been to provide the user with a group for high-precision the bottom was a time function, if the user is properly utilized, time accuracy can be a ms. Accuracy this time, and for most of the real-time control system can meet the requirements.

This paper discusses the establishment and relevant accomplishments of a simple facility used for students learning aids based on the Keplerian Orbit parameters. Three major areas in Orbital Mechanics are discussed in this paper, Orbit of a satellite, Field of View of a satellite and Constellation of Satellites. -This paper discusses the establishment and relevant accomplishments of a simple facility used for students learning aids based on the Keplerian Orbit parameters.
