Abstract: The recent ten-year research progress in the approximation expressions for the temperature integral In the field of thermal analysis kinetics is reviewed. Some new approaches to approximate the temperature integral are introduced, and the relationship between various approximation expressions is presented. The accuracy in calculating kinetic parameters by different integral methods with different approximation expressions is commented, and the methods to avoid the problem of the temperature integral are summarized. The research tendency about the temperature integral is also suggested.
