摘　　要：年轻成年被试在现代人类觉醒期间“标准环境温度”(standard ambient tem-perature)(～20℃)和人体产生和散发热量保持最佳平衡状态的睡眠期间“热中性”(thermal neutrality)环境温度(～30℃)条件下。24-h昼夜测量体(口腔)和皮肤(中背,耳后,肘,手背,足背)温度。皮肤温度借助特制WMSX-01巡回检测温度仅远距离连续测温和自动打印。结果表明;(1)在“标准环境温度”(～20℃)和“热中性”环境温度[～30℃间可见四肢(特别足部)]皮肤温度呈现显著相位性倒转。(2)“非午睡组”和“午睡组”均可见在14:00左右呈现一个体温“钟”的“次要低谷”(Minor nadir),从而表示成年人的体温“钟”也可能具有“半24-h昼夜节律”(Circasemidian rhythm)的内源性特征。Temperature 'clock' was measured by 24-h continuous recordings of body(oral)and skin(middle back, postaural, elbow, hand, foot) temperature in 23healthy young adults. Experiments were undertaken under 'standard ambienttemperature' (～20℃) and 'thermal neutrality' (～30℃) conditions, respec-tively.The former simulated standard temperature condition during wakefulness,whereas the latter simulated the commonly 'quilt' ambient temperature duringsleep. Measurements of skin temperature were done by a specially-equippedmultiple thermographic device model WMSY -01,which allowed 24-h automa- tic recordings of 10 different skin positions of the body at a glance. Resultsshowed: (1) Skin temperature of the extremities (especially foot) showed signi-ficant reversal under 'thermal neutrality' temperature condition(～30℃)whichsimulated the commomly 'quilt' ambient temperature during sleep. (2)A minornadir was observed around 14:00 between 10:00 and 16:00 of the temperature'clock' of both 'non-siesta' and 'siesta' groups, indicating the possible in-volvement of the secasemidian nature of temperature 'clock' in young adultsubjects.
