A model is presented of heat transfer and temperature distributions in the skin and superficial tissues. It is based on a finite difference numerical solution of the one-dimensional multilayer coupled bioheat equation. In this paper, the model is used to investigate the influence of the values of parameters chosen to represent the physiological and heat transfer processes on the temperature of the skin under resting conditions and after insulation of the skin surface. Equilibrium resting temperatures were strongly influenced by deep body temperature especially at lower heat transfer coefficients on the skin surface, but slightly affected by the values chosen for skin blood flow and metabolic heat generation; both the heat transfer coefficients and environmental temperature strongly influenced the surface temperature. After surface insulation the temperature elevation was strongly influenced by the thermal conductivities of tissues, skin blood flow and deep boundary temperature; metabolic heat generation was only significantly at unphysiologically high values.
本文提出了一种皮肤和浅表组织中热传递及温度分布的模型。该模型基于一维多层耦合生物热方程的有限差分数值解。在本文中，该模型用于研究选择用来表示生理和热传递过程的参数值对静息状态下以及皮肤表面隔热后的皮肤温度的影响。平衡静息温度受深部体温的强烈影响，尤其是在皮肤表面传热系数较低时，但受所选皮肤血流和代谢产热值的影响较小；传热系数和环境温度都对表面温度有强烈影响。皮肤表面隔热后，温度升高受组织热导率、皮肤血流和深部边界温度的强烈影响；只有在非生理的高值时，代谢产热才具有显著影响。
