一维转移矩阵中元素间关系的探讨

The discussion of elements'relations in one-dimensional transmission matrix

一维转移矩阵中元素间的关系可以通过多种方法求解.本文首先介绍了在V(x)=V(-x)条件下求解转移矩阵中元素间关系的一般方法,即在确定的宇称下如何找出元素间的具体关系;其次重点讨论了怎样利用波函数的对称性去探寻一维转移矩阵中元素间的关系.结果发现,后一种方法更直观,更简单,更能体现出对整个物理过程的把握和理解.因此在碰到类似的问题时,如能充分运用波函数的对称性,将会给问题的处理带来很大的便利.

The different solutions of elements＇ relations in one-dimensional transmission matrix are discussed. Firstly,if V （x） = V （ - x） is considered, the general method is introduced to find out the relations among elements in transmission matrix. Secondly, we especially discussed how to use the symmetry of wave func- tion to solve the same question. As a result, the later method is more simple and succinct. It also can help us to understand the whole physical process. If the similar situations are confronted, the second method can be used to work out the question. It is more helpful than the others.
