摘　　要：通过两个具体实例，说明了Ｍａｔｈｅｍａｔｉｃａ在传递矩阵法中的应用．特别介绍了用Ｒｅｄｕｃｅ命令求振动系统固有频率的方法，并把所得结果与已有结果作了对比，显示了这一方法的优越性．In this paper, the application of Mathematica in transfer matrix method was demonstrated by two examples. A method using 'reduce' command was given to find the proper frequencies of a vibration system. The result obtained was compared with that in reference [2], which shows the effectiveness of this method.
