In this paper, an object of study in EDN, the square barrier model is set up, the mechanism of electron tunnel effect is discussed in EDN, and the explanation of Bohr quantum theory is given on the spark phenomenon in EDN.

This article discusses the production of quantum theory and how Nernst advanced thermal theorem.

By using a full quantum theory, We investigate the time-evolution properties of the atomic dipole squeezing of the degenerate quantum-beat three-level atom intensity-dependently interacting with a single-mode coherent field, and explore effects of splitting of the lower energy levels .
