摘　　要：本文观察了中国南极中山站越冬队员在不同季节的血压、心率、体温和体重的变化，结果表明：在极夜期间，平均收缩压低于对照和回国后的测量值；而舒张压则在极昼时高于回国后的水平；从早晨到夜间（无论极夜或极昼）血压呈逐渐升高的节律性变化。不同季节所测心率的平均值全部低于对照值，在极夜期间降到了全年的最低水平；心率在一天内的变化趋势与血压有很大的相似性。越冬队员体温的变化均低于对照值，但未达到显著的水平；就一天内不同时相而言，早晨的体温均低于其他时相。在中山站，越冬队员每月平均体重与对照值相比均有增加。上述各项生理指标变化的原因有待进一步研究。这些观察与研究为了解人体在极端环境中适应性生理功能的变化提供了基础数据。his article shows the survey results of 20 Antarctic expedition members' blood pressure and pulse rate in different seasons of a year. The statistical analysis indicate that during polar nights the systolic pressure was lower than the observed in other seasons, and it was at the lowest level of the year and the margin of the highest and lowest level was 6.94 mmHg. The diastolic pressure during polar days was higher than the value observed after the expedition members came back to homeland. The systolic pressure was getting higher from morning to night. The pulse rate value of residents in Antarctica was even lower than baseline, and during the polar nights it reached the bottom value of the year. The body temperature was higher than the basic value during the days in Antarctica, and the charging pattern during a day was quite similar to the systolic pressure. These results provide some physiological parameter of adaptation for winterer in Antarctica. They also provide the basal data to special natural environment.
