The Review of the Phase Transition Radiation

The paper considers the infrared characteristic radiation (IRCR) during the first order phase transitions (crystallization, condensation and sublimation) of water. The experimental results show that when the particles (atoms, molecules, clusters) transfer from a higher energetic level to a lower level, partly of the latent heat will be liberation as the photon. By analyzing and summing up of a large number of references, in this paper, the radiative transfer mechanism is given and the radiative transfer equation is shown correspondingly. Besides, this paper also discusses the experiment of the phase change of water vapor condensation. IRCR can be used to solve some climate problems as well as the energy problem. The purpose of the paper is to have a study of the phase transition process, which will be helpful to us to have a further research about the cloud infrared laser that will contribute to search a forth source of ecologically pure energy by make full use of the energy in the clouds.
