Further Discussions on One Dimensional Infinitely Deep Potential Well Model

One-dimensional infinitely deep potential well(ODIDPW) model is one kind of the fundamental problems in quantum mechanics.This paper firstly uses the coordinate-momentum uncertainty relation and the operator theory respectively to prove why the energy of particles in ODIDPW is always greater than zero,and then makes a further discussions on stationary state wavefunction,the quantization of physical quantity,energy level interval,zero-point energy,the coordinate-momentum uncertainty relation and the applicable condition of the ODIDPW model.
