| 摘 要： | 对一名中国南极考察队员在南极中山站长期居留期间的血压、心率、体温作了３４２天的连续观察，结果显示：除舒张压无明显变化外，晚间收缩压、心率、体温的总均值有明显升高，与气温、气压和相对湿度无明显关系。极夜期间的收缩压、体温无明显变化。夜间收缩压趋向升高，但未达到显著水平，而舒张压则有非常明显的下降，夜间心率也有明显的增加。极昼期间早晨的血压、心率、体温比夜间有显著升高，但未超出正常生理范围，此时期早晨的收缩压与气压、晚间收缩压与相对湿度、晚间体温与相对湿度均有明显正相关。极夜与极昼时相比早晨的收缩压、体温均无明显变化，只有心率变化显著；极夜期间的舒张压和体温均低于极昼期间的测量值。

| Abstract: | This paper reported a 342 day continuous observation of the blood pressure,heart rate and body temperature of a member during his long term stay at Zhongshan Station, Antarctica. The result showed that there was no obvious change in the subject diastolic blood pressure,but his night systolic blood pressure,heart rate and the average of his body temperature all increased obviously, unrelated to the changes in air temperature, atmospheric pressure and relative humidity. There was no clear change in his systolic blood pressure and body temperature during polar night. During the night, his diastolic blood pressure increased, though not to a significantly different level, his diastolic blood pressure dropped obviously, and his heart rate also clearly increased. During polar day, his blood pressure,heart rate and temperature were higher in the morning than in the evening, though both remained in the normal range. Also during polar day, his morning systolic blood pressure and the atmosphere pressure, his night systolic blood pressure and the relative humidity, as well as his night body temperature and the relative humidity were all obviously positively correlated. Comparing polar night and day, there was no obvious difference in his morning systolic blood pressure and his body temperature, while there was obvious difference in his heart rate. His diastolic blood pressure during polar night and body temperature were both lower than the measures during polar day. This study can possibly provide some valuable information for the study of Circulative Physiology and Applied Physiology in the special environments. |
