说明：  这个是交通流ＣＡ模型，能够较为真实的仿真出交通流的运行状况，对交通流元胞自动机的人可以学习学习(The CA model of traffic flow, to a more realistic simulation of the operational status of the traffic flow, traffic flow cellular automaton can learn to learn)

灰色预测的模型，我们用它做过东北三省的数学建模比赛并取得不错的成绩。(The grey prediction model, we use it for the mathematical modeling contest in the three provinces of Northeast China and achieved good results.)

boost电路仿真，元件采用的是igbt，用触发脉冲触发的(boost simuliation The components are IGBT and triggered by trigger pulse.)

给音乐添加噪声再通过低通滤波器滤掉噪声，性能改善过后能明显看到效果。(Add noise to the music and through a low pass filter filters noise, performance improvement can be evident after the effects.)

基于matlab的字母识别，基于模板匹配，因为采用区域生长法，速度可能有些慢！(Base on matlab!)
