摘　　要：我们曾用不同针术刺激同一穴位,在相关的皮神经和肌神经上都可引导出各具特征的、可以作为针下反应对比性指标的“针刺诱发电位图”,进而指出皮神经和肌神经中传导针刺信息的纤维类别亦因针术不同而有差异。这些现象的出现必然和浅、深感受器的针刺反应有着不可分割的内在联系。本文报导不同术式针刺与皮肤感受器放电反应的规律性关系。Nine typs of mechanoreeceptors of hair skin in 46 rabbits were identified by recording discharges of single afferent fiber in posterior femoral cutaneous nerve from fine filaments by' dissection. When seven manipulations, i.c.lift and thrust,twist and twirl,rotate,serape,flike the needle and finger-pressure were used to stimulate each receptor,their responsive discharges were observed,Data at 165 units were collected totelly,89 units in which were for the relatiou between manipulations and discharge patterns,and the other 76 units for discharges responding to mauipulations at different distances from the receptive field. Nine types of receptors having been observed are able to responde to any acupuncture manipulatins,it is thus clear that there is not any special 'acupucture receptor.' Same kind of discharge pattern existed in different types of receptor when stimulated by the same acupuacture manipulation, whereas clifferenct discharge patterns can be found at the same unit when the manipulation changed.We belive that it is due to the movement form, force amount and time duration of the manipulations. Receptors responding to acupuncture were not limited to one point only, but involving a certain field surrounding the needle point.The size of this field varied with the types of receptors and kinds of manipulations. Our previous articles had reported that the acupuncture photograph leading from nerve and building on impulses induced by acupuncture and the groups of afferent fibers conducting acupuncture signals changed with different manipula- tions,in this paper the reasons for that have been expounded by presenting the relationship between the responsive discharges of receptors and the manipulations The significance of revealing the relation between acupuncture manipulations and systems for the research of acupuncture mechanisms and to advance the acupuncture manipulations is discussed properly,and point out in the meantime that there have with substantial scientific contents within the acupuncture manipulations
