The magic of nature forever fascinated mankind. With the development of The Times, science and technology has been continuously progress and electronic computer technology is also with each passing day, which promote and inspire people continue to ascertain world charm. Reentrant phase transition behavior of complex liquid is one of the very popular topic,More and more researchers have joined in the research.The phase transition of the system is generally the traditional phase transition. But the study reentrant phase transition of the system has made many achievements, and also constantly further improved. This article first briefly describes the differences between reentrant phase transition and phase transition of the traditional, and briefly introduces the research background and research status of reentrant phase transition behavior of complex liquids, as well as the research significance. At last, the paper introduces the origin, classification and critical phenomena of phase transition, as well as complex liquid reentrant phase diagram.The study of complex liquid reentrant phase transition is more complex, so it is necessary to simplify some of the physical and mathematical models, to facilitate the calculation of research work. The Ising model is the most simple model, and it has long been applied to the study of phase change. The third chapter of the paper briefly introduces the research background and progress of the Ising model research, Also introduces the mathematical framework and characteristics of the Ising model, and introduces the research progress and research methods of some models, which focuses on the Monte Carlo(Monte Carlo) simulation technology.In the fourth chapter, we study and analyze the phase diagram of the phase transition behavior of the complex liquid. Through some phase diagrams and the relative density curve, we can find some parameters such as the exchange interaction parameters of the phase diagram, the transverse magnetic field coupling parameters, sequence parameters and so on have larger influence on phase diagram. The global phase diagram of the reentrant phase transition of complex liquid is also introduced. Using the control variable method, by changing various parameters, the computer software is used to describe the various 3D phase diagram, the study found that there is correlation between various parameters of the system. The research method and also is helpful to explore and research phase change of the other systems.On the whole, the related knowledge and technology of the phase transformation, especially the complex liquid, can be summarized in the paper, which provides some knowledge and technical framework for the study and exploration of the transformation of the later generations. Some calculation methods and ideas mentioned in this paper, as well as the Ising model can even be applied to the study of various phenomena in various fields, such as the evolution of the complex network of public opinion, forest fires, urban complex traffic etc.
