在J506船往返航行于东经122°32′、北纬29°50′至东经172°33′、南纬7°00′之间的过程中,测定了相应环境参数和36人共44人次的6项生理指标。舰船在热带海域航行,舱内平均三球温度指数不超过32℃、劳动负荷不大的情况下,机电人员的6项生理指标(体温、脉率、心电图、3小时出汗率、24小时尿量和尿盐量)根据测得的结果,作出初步结论:均在生理耐受范围以内,但在加大体力负荷时,可使机体迅速产生热蓄积,引起体温升高和脉率增加。 在从高纬度短时间内进入低纬度海域执行任务前,应该根据该海域的气象条件进行热适应训练,否则会发生热不适应,甚至增加中暑的发病率。 舰员在热带海域航行期间3小时出汗量为0.5～1.5 L,水、盐代谢仍能维持平衡,不必进行特殊补充。
During the round-trip voyage of J506 between 122 ° 32’E, 29 ° 50’N, 172 ° 33’E and 7 ° 00’S, 6 environmental factors and 36 persons with a total of 44 persons were measured Physiological indicators. The ship navigable in the tropical sea, the average three-ball temperature index in the cabin does not exceed 32 ℃, and the work load is not large, the six physiological indexes (temperature, pulse rate, electrocardiogram, 3hours sweat rate, 24 hours Urine volume and urinary salt) According to the measured results, the preliminary conclusions are made: all within the range of physiological tolerance, but increase the physical load, the body can quickly generate heat accumulation, causing increased body temperature and pulse rate. Before carrying out the task of entering the low latitude area from a high altitude in a short period of time, it should be acclimated according to the meteorological conditions in the sea area. Otherwise, it will cause thermal acclimation and even increase the incidence of heat stroke. Crew in the tropical waters 3 hours during the sweating volume of 0.5 ~ 1.5 L, water, salt metabolism can still maintain the balance, without special supplements.
