Abstract: 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.

Key words: node theorem, variation theorem, wave functions, bound states
