图论程序：图的关联距阵，最小生成树，深度搜索，欧拉图，连通性，权值矩阵等，有GUI(The correlation of the graph, the minimum spanning tree, the depth search, the Euler diagram, the connectivity, the weight matrix, etc., with a GUI)

OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。(OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.)

随机共振程序可以直接用。非常好的(Stochastic resonance program can be used directly.Very useful)

对于给定的结构振动响应数据（时间序列信号）， 该程序可以分解成多个订单这些响应信号 小波子信号，然后计算出分信号能量spectum。 (For a given structural vibration response data (time series), the program can be decomposed into multiple sub-orders for the response signal wavelet signal, and then calculate the sub-signal energy spectum.)
