For the temperature distribution problem of multilayer thermal protective clothing, pde tool kit optimization and one-dimensional Matlab unidirectional search algorithm were used to establish a non-steady static human body-clothing-environment heat exchange pool and two-dimensional heat conduction model. In addition, Matlab, Lingo, and Excel were applied to solve a series of relevant problems. For the two-dimensional heat transfer problem, model optimization was conducted, and the values of time and space intervals were taken rationally to subdivide the grid and accelerate the rate of model algorithm.

Key words: X-ray absorptivity Fourier heat transfer model, one-dimensional Matlab unidirectional search, thermal protective clothing under high temperature
