老虎吃兔子是一个典型的非线性系统,当老虎数量多的时候,兔子就容易被吃,兔子数量减少,兔子数量较少,老虎捕兔困难,老虎就饿死,老虎数量减少后,兔子繁殖加快,从而使得兔子数量增加,老虎捕食又变得容易了。利用C语言编程、利用4阶龙格-库塔法就可验证老虎与兔子的非线性生态现象。-Tiger eating rabbit is a typical nonlinear system, when the tiger population and more often, it is easy to be rabbit food, rabbit decrease in the number of rabbit small number of rabbits caught tiger difficulties, tiger starved to death, reduce the number of tigers, the rabbit breeding to speed up, resulting increase in the number of rabbit, the tiger has become easy prey. The use of C language programming, using 4-order Runge- Kutta method can verify the tiger and rabbit non-linear ecological phenomena.

信息社会的高科技,商品经济化的高效益,使计算机的应用已普及到经济和社生活的各个领域。计算机虽然与人类的关系愈来愈密切,还有人由于计算机操作不方便继续用手工劳动。为了适应现代社会人们高度强烈的时间观念,考试系统软件为教学办公带来了极大的方便。该软件是以VB编程语言为主实现语言,其功能在系统内部有源代码直接完成。通过操作手册,使用者可以了解本软件的基本工作原理。-information society technology, commodity economy of the high effectiveness and the application of computers have access to the economy and society in all areas of life. Although computer and human relations more closely, it was inconvenient for computer operators continue to use manual labor. In order to adapt to modern society was highly strong concept of time, the examination system software for teaching office brought great convenience. The software is Visual Basic programming language mainly to achieve language, and its function within the system active code directly completed. Through the operations manual, users of the software can understand the basic principle.
