摘要
针对一维定态薛定谔方程的束缚态,基于量子力学的变分原理,证明了其波函数的节点定理.基本思路是根据束缚态波函数的节点构造恰当的试探波函数.
Based on the variation theorem in quantum mechanics, we prove the node theorem of wave functions for bound states of the one-dimensional stationary Schrodinger equation. The basic idea is constructing proper trial wave functions according to the nodes of the bound states.
