蚁群算法是一种模仿蚁群行为的仿生优化算法，其实现机理包括两个基本阶段：适应阶段和协作阶段。在适应阶段，各可行解根据积累的信息不断调整自身结构，路径上经过的蚂蚁越多，信息量越大，则该路径越容易被选择：时间越长，信息量越小。在协作阶段，各可行解之间通过信息交流，以期望产生性能更好的解。(Ant colony algorithm is a mimic ant colony behavior of bionic optimization algorithm, its implementation mechanism includes two basic stages: adaptation and collaboration. In adaptive phase, the feasible solution according to the accumulated information constantly adjust their structure, path through the more the ants, the greater the amount of information, it is the easier path is chosen: the longer the time, the smaller the amount of information. The collaboration stage, through the exchange of information between the feasible solution, expecting to generate better solutions.)

计算了5 元侧射阵，阵间间距分别为0.25、0.5、0.8倍波长的方向图(Calculation of five yuan side shot array, the array spacing between wavelengths respectively 0.25,0.5,0.8 times pattern)

说明：  基于MATLAB的FIR带阻数字滤波器的设计 由于生物医学信号处理过程中易混入50Hz噪声的特点，本文利用程序设计法和FDATool设计法，设 计一带阻滤波器，并将设计的滤波器应用到一混和正弦信号，通过测试检验，该滤波器可以很好地消除50Hz的工 频干扰。(】To prevent the biomedical signals from being disturbed by 50Hz noise easily，the paper designs a bandstop digital filter by procedure and FDATool method．The filter is tested by a blended 81ne wave experimentally and the result shows that the filter can cancel the 50Hz noise very well．)
