中文摘要：

目的：通过比较分析督脉循行线上红外辐射轨迹（IRRTM）与微循环血流灌注量,探讨督脉循行线上IRRTM产生的原因。方法：分别使用红外热像仪系统和三通道激光多谱勒血流仪观察人体背部督脉IRRTM、表面微循环血流灌注量以及在督脉线上加热皮温扩展情况。结果：1在自然状态下,人体体表可以观察到与古典十四经脉循行路线基本一致的IRRTM,并处于动态变化过程之中。2背部督脉的IRRTM的出现率最高占50.56%。3督脉线上的命门、脊中、至阳、身柱4个穴位和十二胸椎1个非穴位的皮肤微循环血流灌注量均要比其左右两侧旁开1cm非经对照部位高,有显著性差异（P〈0.01）。4在督脉线上加热,皮温会沿着督脉方向双向传导,具有良好的导热特性。结论：督脉循行线上IRRTM的形成与其相关组织的微循环血流灌注量密切相关。

英文摘要：

Objective： Through comparing and analyzing the changes of infrared radiant track along meridian course（IRRTM） and micro-blood flow perfusion along DU meridian, to investigate the reason on the generation of IRRTM. Methods： Using infrared camera system and the three-channel laser Doppler blood flow meter, the IRRTM, micro-blood flow perfusion and extension of heated skin along human Du Meridian were observed. Results： 1IRRTM, which was consistent with the classical meridian line described in ancient books, could be observed on human body in normal condition with dynamic change. 2The emergence rate of IRRTM along Du Meridian was the highest occurrence rate of 50.56%. 3Micro-blood flow perfusion on DU4, DU6, DU9, DU12 and non-acupoint on twelve thoracic was highered than nonmeridian control points that 1cm from the left and right sides in normal condition, the difference was statistically significant（0.01）. 4Skin temperature displayed a two-way expansion along the meridian by local heating the acupuncture points on Du Meridian. Conclusion： Formation of IRRTM along Du Meridian is closely related to the organizations＇ micro-blood flow perfusion.
