在一个具有几个顶点的连通图G中，如果存在子图G 包含G中所有顶点和一部分边，且不形成回路，则称G 为图G的生成树，代价最小生成树则称为最小生成树(If there subgraph G ' contains all vertices in G, and part of the side, and does not form a loop, then G' in a few vertices connected graph G is the spanning tree of a graph G consideration of the minimum spanning tree is called minimum spanning tree)

基于RBF神经网络的短期客流预测，开发环境matlab，两个m文件，一个是选择数据的，另一个是主文件(Based on RBF neural network short-term passenger flow forecast, the development environment matlab, two m documents, is a choice of the data, the other is a master file)

说明：  模拟有限元仿真中的力分布，变形量大小分布(force distribution simulation in FEM)

说明：  使用matlab/simulink进行风机叶转矩角的模糊控制模型。采用模糊控制器件直接进行搭建(Using matlab/simulink for fan leaf angle torque fuzzy control model. Fuzzy control device built directly)

相干与非相干成像系统的比较。复习光学传递函数OTF的概念，以及该函数与相干传递函数CTF的关系。用OTF完成单透镜系统成像的计算。(The comparison of coherent and incoherent imaging system.Review the concept of OTF, optical transfer function and the function relations with CTF coherent transfer function.Complete the single lens imaging system with OTF calculation.)

说明：  悬臂梁振动主动控制，pid控制，控制效果非常好(Active control of cantilever vibration, PID control, control effect is very good)

灰色系统知道系统的一些简单信息，但是并没有完全了解该系统，只能根据统计推断或某种逻辑思维来研究该系统。(The gray system know some simple information system, but did not fully understand the system, to study the system can only be based on statistical inference, or some kind of logical thinking.)
