其他摘要：Seven male students were exposed to four varied air temperature environments: hot (37℃) to neutral (27℃) (HN), neutral to hot (NH), cool (17℃) to neutral (CN), and neutral to cool (NC). The air temperature was maintained at the first condition for 20 min, then was changed to the second condition after 15 min and was held there for 20 min. Each subject wore a T-shirt, briefs, trunks, and socks. Each sat on a chair and was continuously evaluated for thermal sensation, thermal comfort, and air velocity sensation. Some physiological and thermal parameters were also measured every 5 s during the experiment. The correlation between thermal sensation and skin temperature at 15 sites was found to be poor. The subjects felt much warmer during the rising phase of the air temperature (CN, NH) than during the descending phase (HN, NC) at a given mean skin temperature. However, thermal sensation at the same heat flux or at the same value of the difference between skin and air temperature (Δ(T_ - T_a)) was not so different among the four experimental conditions, and the correlation between thermal sensation and heat flux or Δ(T_ - T_a) was fairly good. The multiple regression equation of the thermal sensation (TS) on 15 sites of skin temperature (T_; ℃) was calculated and the coefficient of determination (R) was found to be 0.656. Higher coefficients of determination were found in the equations of thermal sensation for the heat flux (H; kcal・m^<-2>・h^<-1>) at the right and left thighs of the subjects and on Δ(T_ - T_a) (℃) at 4 sites. They were as follows: TS=2.04 - 0.016 H_ - 0.036 H_; R=0.717, TS=1.649 + 0.013 Δ(T_ - T_a)_ - 0.036 Δ(T_ - T_a)_ - 0.223 Δ(T_ - T_a)_ - 0.836 Δ(T_ - T_a)_; R=0.752, respectively.
