摘　　要：为观察模拟失重条件下体温调节的特点，５名健康男性－６°头低位卧床７ｄ、对照３ｄ、恢复２ｄ。结果表明：卧床中体温保持了觉醒－睡眠的昼夜变化规律，但节律发生了一定改变，直肠温度昼夜节律的改变主要出现在卧床初期；卧床期间，淋巴细胞胞浆中热应激蛋白（ＨＳＰ７０）的含量明显增加，头颈部皮肤温度明显升高，温度分布改变。The effect of simulated weightlessness on thermoregulation was studied in 5 subjects.The experiment consisted of 3d baseline measurements, 7 d head-down bed rest and 2d recovery. Circadian rhyth was assessed by continuous measurements of rectal temperature and skin temperature with 2 h intervals. Heat Stress Protein 70(HSP 70 ) was measured by Western-blot Dot method and the facial surface temperature distribution was measured by HR-2 infrared thermography. The results showed that rectal temperature keeps the wake-sleep variation, but the circadian rhythm changed during bed rest, and the change of rectum temperature rhythm appeared mainly in the early-days of bed rest; HSP 70 and facial surface temperature increased during bed rest.
