Waves of Probability and the Problems of Torsion for Quantum Effect

OuYang Shoucheng,Li Zhilan,Yuan Dongsheng

Strategic Study of CAE 2005, Volume 7, Issue 6,   Pages 1-6

Abstract:

In this paper, the numerical experiment is conducted for Schrödinger's equivalent equation with third order derivative for nonlinear variable. The results show that the probability of probability waves is the quasi-regular flow under given condition, and it's a result of comprehensive interactions among intensity of potential field and particle density and torsion (spin) field with the quantum effect. The pure quantum effect is represented only by irregular flow.
