高温作业的评价是一个比较复杂的问题,既要综合各种气象条件(气温、气湿、辐射热和风速),又要结合劳动强度、劳动方式和机体情况,包括机体的适应能力。因此在多数情况下,都难以根据一个单一的数值来进行评价。目前国内外一些常用的高温作业评价指标,如热量交换计算、湿球—黑球指数,有效温度、干球—黑球—相对代谢率指数,以及四小时出汗率等,都是从一定的特点来考虑高温对机体的影响。这些评价指
Evaluation of high-temperature operation is a complex issue that combines both meteorological conditions (temperature, humidity, radiant heat and wind speed) as well as labor intensity, working style and body condition, including the body’s ability to adapt. Therefore, in most cases, it is difficult to evaluate based on a single value. At present, some commonly used indicators of high temperature operation at home and abroad, such as heat exchange calculation, wet bulb - black ball index, effective temperature, dry bulb - black ball - relative metabolic rate index, and four hours of sweat rate are from a certain Features to consider the impact of high temperature on the body. These comments mean
