摘要?目的：利用艾灸設備進行保健灸，建立正常人體艾灸的物理學劑量，為進一步研究患者艾灸劑量范圍提供依據。方法：利用自制高精度溫度傳感器測定手足部、胸腹部及腰背部等穴位灸前瞬時溫度，最高耐受瞬時溫度，并記錄產生最高耐受瞬時溫度所需要的時間，通過自定義公式：穴位艾灸的物理學劑量=（灸前瞬時溫度+最高耐受溫度）/2×產生最高耐受溫度所需要的時間，擬建立不同部位穴位的艾灸物理學劑量范圍，并分析艾灸不同部位的物理學劑量范圍差異。結果：手陰經的穴位艾灸時所需要的物理學劑量低于足陰經、胸腹部的穴位，手陽經的穴位艾灸時所需的物理學劑量低于足陽經、背腰部穴位，提示艾灸時手部經穴所需的物理學劑量低于足部及軀干部的穴位，說明手部穴位較之足部、軀干部穴位對光熱更敏感。結論：不同部位的穴位均有一定的劑量范圍，進行灸療時，只要達到穴位的劑量范圍，即可取得相應的效果。

Abstract?Objective：To establish the physical dosage of moxibustion in normal human body by using moxibustion equipment for health care moxibustion，so as to provide basis for further study on the dosage range of moxibustion in patients. Methods：Before moxibustion，the instantaneous temperatures of acupoints at hands，feet，thorax，abdomen，waist and back，and their maximum endurance instantaneous temperatures were measured by self-made high-precision temperature sensor. The time of each acupoint to produce the maximum endurance instantaneous temperature was recorded. The physical dose of moxibustion at each acupoint was defined as follows：（instantaneous temperature before moxibustion + maximum endurance temperature）/ 2×（the time required to produce the maximum tolerance temperature）. So，the physical dose range of moxibustion at each acupoint was to be established，and the differences of the physical dosage ranges among different parts of moxibustion were analyzed. Results：The physical dosage of moxibustion at each acupoint of yin meridians of hand was lower than that at each acupoint of yin meridians of foot，thorax and abdomen. The physical dosage of moxibustion at each acupoint of yang meridians of hand was lower than that at each acupoint of yang meridians of foot，waist and back. It suggested that the physical dosage of moxibustion at the hand meridian acupoint was lower than that at the acupoint of feet and trunk，indicating that compared with foot and trunk acupoints，hand acupoints were more sensitive to light and heat. Conclusion：Acupoints of different parts have certain dosage ranges. When moxibustion is carried out，the corresponding effect can be achieved as long as the dosage range of the acupoint is reached.

溫熱刺激是灸法臨床治病的最為關鍵的因素之一[1]，灸法的療效與溫熱刺激密切相關，而溫熱刺激的大小通過艾灸劑量即灸量來調節，現代研究對灸距及灸時上進行了規范研究，證實不同的灸量可以產生不同的治療效果，但灸量的調節仍然存在不可控因素[2]。……
