且亮带的辉度与热感的程度呈正变关系;而3This paper reported the observd results on changes of the infrared thermal image of upper extremity induced by needled“Hega” (LI 4)

“Daling”(P 7) and “Neiguan” (P6) points. The results indicated that 10 out of 23 cases whose higher and middle temperature bands of upper extremity distribted along the “Daehang” (Large Intestine) channels

when they felt phenomena of propagated sensation along the “Dachang” channels induced by needled “Hegu” points. Those effects did not appear in the objects who didnot feel PSC along the “Dachang" channels induced by needled points. Above results provide an objective basis for the phenomena of channels and suggest that the phenomenon of PSC is an objective fact in human body.
