Under the high temperature conditioning in fireground and in order to protect people with high temperature protective clothing, this paper has divided the structure of human body into four parts according to characteristics of human body structure and established the heat transmission model from interior side of human body-skin layer-gap layer-protective clothing layer-environment. The temperature distribution situation has been summarized with explicit difference method and C-N implicit difference method respectively. By comparing the actual situation in fireground, the protective clothing can protect people under both two different methods which illustrates that this model is suitable for solving the temperature change of special clothing for high temperature operation. Considering the human skin stratification and compared with the explicit difference, the deviation of implicit difference solution is smaller. The model solution method in this paper is more stable and the result is more suitable to actual situation. [ABSTRACT FROM AUTHOR]
