从能量角度透视提插补泻与徐疾补泻

Discussion on reinforcing-reducing method by lifting and thrusting the needle and slow-rapid reinforcing-reducing method from the point of view of energy

目的:解决提插补泻与徐疾补泻在论述上的矛盾。方法:在一定的条件下,利用动能定理,推导出外力(术者施加于针的作用力和一切阻碍针体运动的力的合力)和针体运动速度的关系,从而得出当术者用力下插或上提针时,针的运动速度增加。结论:提插补泻中重插轻提与轻插重提的轻重应理解为进退针幅度的大小;徐疾补泻中的徐疾应理解为速度的快慢。

Objective To resolve the contradictory in expounding of reinforcing and reducing by lifting and thrustion the needle and slow-rapid reinforcing and reducing method. Methods In a certain condition,the relationship between the external force （the joint force of both the force pressing on the needle and the force arresting the needle＇s moving） and the speed of needle＇s moving is deduced by means of kinetic energy theorem, so, when the needle is heavily thrust or lifted, the speed of its moving will be increased. Conclusion In the reinforcing and reducing method by lifting and thrusting the needle, ＂heavily＂and ＂gently＂ of heavily thrustiing and gently lifting or gently thrusting and heavily lifting should be considered as differences of the amplitudes of lifting and thrusting the needle; ＂slow-rapid＂ of slow-rapid reinforcing and reducing method should be considered as difference of the speeds.
