这个程序是由关礼物的，挺好的，很实用，省的自己算不过来(this program is about gift)

汽车大灯开关节点C语言编程，基于飞思卡尔芯片程序(Automotive headlight switch node C programming language, based on Freescale chips)

中国海域潮汐预报软件Chinatide的应用(China Sea tide forecasts Chinatide application software)

随着社会发展的不断进步，民航事业的壮大，人们消费水平的提高，乘坐民航的消费着也越来越多。预定查询系统因此在各机票预定网点中的作用也越显重要，因此，开发一套实时机票预定系统更现紧迫。机票预定系统应克服存储乘客信息少，查询效率低下等问题外，更重要的是其安全性，可靠性，这关系到航班和乘客的安全及准确，本系统因面向广大机票预定网点。重点是销售系统中的方便快捷。(with social development progresses, the growth of civil aviation, people raise the level of consumption. CAD ride to the consumer more and more. Scheduled inquiry system in booking tickets for the networks is the role of the more important, therefore, development of a real-time ticket reservation systems are more pressing. Ticket reservation systems storage passengers should overcome the scarcity of information, inquiries inefficient issues, even more important is their safety, reliability, the relationship of flights and passenger safety and accuracy, the system for booking tickets for the large-oriented networks. Focus on the marketing system convenient and quick.)

该项目首先是利用单片机对鱼缸的温度进行智能控制。首先通过外部按键对鱼缸所需温度进行设定。温度传感器 DS18B20 采集温度信息在外围的 LCD 上显示出来。其次是利用光电耦合器判断有无鱼饵，若无鱼饵，发出提示，若有鱼饵，则执行自动投食或手动投食功能。(The project first is the use of single-chip microcomputer to control the temperature of the fish tank. First, the temperature of the fish tank is set by the external button. The temperature sensor DS18B20 collects the temperature information to display on the periphery LCD. Followed by using photoelectric coupler to determine whether the bait, if there is no bait, alert, if there is a bait, automatic throw in and throw food or manually cast and functional food.)

面向对象、设计模式与性能 有些C/C++开发者有些奇怪的观念。他们认为使用面向对象和设计模式会降低程序的性能。但V8证明了这种观念是错误的。V8的实现使用了许多设计模式，但依然非常高效。 下面列出V8中使用的两个模式： 工厂模式 当Javascript引擎执行一个脚本时，引擎为遇到的每个变量、函数或数组都创建一个实例。JSObject是所有这些对象的父对象(Object oriented, design patterns and performance Some C/C++ developers have some strange ideas. They believe that the use of object-oriented and design patterns will reduce the performance of the program. But V8 proved that this idea is wrong. V8 implementation uses a number of design patterns, but still very efficient. The following lists the two models used in V8: Factory mode When a Javascript engine s a script, the engine creates an instance of each variable, function, or array encountered by the engine. JSObject is the parent of all of these objects.)

以定时的方式接收下位机传送的多帧数据，接收准确，实时性很强(In time to receive the next crew of the multi-frame data transmission, receive accurate, real-time strong)

说明：  用VB语言写的asp.net程序，主要是针对实例进行编写，适合初学者(VB language Asp. Net written procedures is targeted mainly to prepare for example, for beginners)

假定一维整型数组a[n]中的每个元素值均在[0,200]区间内,分别统计出落在[0,20],[20,50],[50,80],[80,130],[130,200]等各区间内的元素个数；(Assume a one-dimensional integer array a [n] each element of the values ​ ​ are in the range [0,200] interval, respectively, the statistics fall [0,20], [20, 50], [50, 80], [, 130] , element number [130,200], etc. of each interval )
