中暑是人们在高温高湿的环境中工作所引起的体温调节障碍、水盐代谢紊乱及神经系统功能损害。 1.野外人员中暑的常见原因野外地勘人员发生中暑,以7月份为甚。从一天的时间来看,上午10点钟到下午3点钟这段时间容易发生中暑。夏季室外日光直射下的辐射强度约62.80J(1.5卡)/(cm~2·min),即等于人能耐受的强度。一般来说,气温超过34℃,就可能发生中暑。地勘露天作业人员,出于长时间在炎热的阳光曝晒下工作,不仅受日光直射,而且还受到地面上大量物体的高温二次辐射,同时夏天相对湿度又大,特别是在荆棘丛生的山地
Heat stroke is a disorder in body temperature regulation, disturbance of water and salt metabolism and nervous system dysfunction caused by people working in a high-temperature, high-humidity environment. 1 field common causes of heat stroke field geologists in the heat stroke, July is even more. From a day’s time, 10 o’clock in the morning to 3 o’clock this time prone to stroke. The intensity of radiation under outdoor direct sunlight in summer is about 62.80J (1.5 calories) / (cm ~ 2 · min), which is equal to the intensity that human beings can tolerate. In general, the temperature exceeds 34 ℃, heat stroke may occur. Open-pit crews, exposed to prolonged exposure to the sun’s rays of heat, are not only exposed to direct sunlight, but are also subject to high-temperature secondary radiation from a large number of objects on the ground while their relative humidity is high in summer, especially in thorny mountainous areas
