英文摘要：

A hybrid model which combines Pennes equation with W-J equation, is used to model three-dimensional （3D） heat transfer in arm. The model is based on anatomy. The steady-state temperature field in arm by use of finite element method is calculated. The influences of heat transfer in arm caused by the blood perfusion, metabolized heat, environmental temperature and air convective heat transfer coefficient are especially analyzed. According to the results, blood perfusion plays an important role in maintaining the body temperature in the normal range. This research has great signification in analyzing the form mechanism of temperature distribution of the body surface.
