摘要
The term "thermal stability of the human body" is introduced by an analogy with the stability of the stationary state of an irreversible thermodynamics system. The measure of stability of the human body thermal state, evaporative resistance parameter h(e)(-1) hPa. (W.m(-2))(-1), is applied. The parameter expresses a deviation (in hPa) in the human body thermal state caused by the change with 1 W.m-2 of intensity in affecting heat Bows. Estimates of the dynamics of the parameter h(e)(-1) are used to determine the body's thermal stability with relation to the change in environmental thermal parameters and altitude. The human body thermal comfort stability is also discussed. (C) 1998 Elsevier Science Ltd. All rights reserved.
