摘　　要：黑球低温卡他温度计是评价环境气温、风速与太阳辐射所形成的综合冷强度的一种仪器,它由玻璃制成,结构简单,不需要电子元件和特殊电源。体积小,重量轻,价格便宜,利于推广使用。提出了由降温时间及其推导出的黑卡等效温度来综合评价环境冷强度的可行性。Two low temperature katathermometers (LTKs) of different temperature scales, from 2℃ to -2℃ and 6℃ to 0℃, were designed to evaluate cold environment. Under various air temperature (Ta,℃), wind velocity (V, m / s) and the intensity of simulated radiation, (R, kJ· m^2·h^(-1)) in a climatic chamber, the time (T, min) required to reduce the temperature from the upper limit to the lower limit of the scale were recorded. The regression equations between T and meteorological parameters (Ta, V and R) were established with data of 1 064 measurements. The black kata equivalent temperature (BKET,℃) was advanced to appraise the stress of the cold envi- ronments.
