摘要
人体通过辐射、对流、传导和蒸发与环境交换热量。热平衡方程S = M-E-(+/- W)- c - r中的每个热交换项都与环境条件和服装的影响有关，已作了进一步的详细描述。风速、平均辐射温度、空气中的水蒸气压、服装的隔热和透气性等因素都是考虑的因素。对于动态条件，或者对于需要考虑身体特定区域的条件，建议使用动态数学模型。
The human body exchanges heat with its environment via radiation, convection, conduction and evaporation. Each of the heat exchange terms in the heat balance equation S = M-E-(+/- W)-C-R has been described in further detail as related to environmental conditions and to the effect of clothing. Such factors as air velocity, mean radiant temperature, water vapor pressure in the air and thermal insulation and vapor permeability of clothing are factors which are considered. For dynamic conditions, or for conditions requiring consideration of specific areas of the body, the use of a dynamic mathematical model is recommended.
