【摘要】 对11名健康人的55个穴位及更多的非穴位机械振动测定,发现身体各部位有低频振动,频率在5～9Hz其频率与振幅在穴位或与其相邻5mm的非穴位上并无差别。各部位振动频率与心搏不同步,甚至在同一经上各点频率也不一定相同,所以体表机械振动不是主要来自心脏,不论穴位或非穴位对200Hz,等幅人工机械波的传播行为相同,振幅的自然对数随距离震源增大而迅速衰减,而与经络或穴位无关。机械波并不沿着任何特定的线路传播。 从实测的理论分析,人体上存在低频机械波导的可能性极小,不能把经络的本质简单地看作是物理上的机械波导。更多还原

【Abstract】 <ABSTRACT>It was thought that in human body there were low frequency mechanicalwave ("guides" being the essence of the channels in traditional Chinesemedicine ) and the vibration on the body surface came from the heart-beatand propagated through these guides .The mechanical vibration with lowfrequencies (5～9Hz ) was recorded in 11 normal subjects from 55 acupointsand a lot of unacupoints and results showed that there was no significantdifference between acupoints and unacupoints either in amplitude or infrequency of vibration. The frequencies of vibration from various parts werenot synchronous with the heartbeat. Besides, the frequencies of vibrationof various acupoints along the same channel were not identical. So, theauthors sugest that these mechanical vibrations seemed not to come mainlyfrom the heart-beat.Both the acupoint and unacupoint at various parts of the body havethe same display in propagating a 200Hz artificial mechanical wave withuniform amplitude emitting from a certain point of the body. It was shownthat the natural logarithm of the amplitude reduced rapidly with theincreased distance, but it was not related to the channels or acupoints. Themechanical waves propagated in all directions but not in a linear way.更多还原
