OBJECTIVETo describe physiology of channels and circulation of qi and blood from the point of view of mechanics.

METHODSThe equation of no compressive normal Newtonian fluid electric osmotic motion are solved by using numerical value method.

RESULTSThe results of numerical value calculation show that the flow rate of fluid of channel lines is confirm to the migration velocity of middle-small molecules in literature. When the osmotic coefficient of blood vessel wall and blood pressure of the end of artery changes, the flow rate of qi will correspondingly change, which is confirm with the physiologic reaction at acupuncture. If the static pressure of the channel lines and the inflow condition are changed, it can explain the theory of qi stagnation and blood stasis, and flow of qi inducing blood circulation.

CONCLUSIONBy using the equation of electric osmotic flow, the theory of traditional Chinese medicine can be explained, which is conducive to understanding the conduction phenomena of electric wave and electric current of channels and collaterals.
