1、脉诊Pulse-taking脉诊Pulse-taking脉诊是医者用手指触按患者一定部位的脉搏，以体察脉象、了解病情的一种诊病方法。机理—略脉象的形成与诸脏腑、气血的功能密切相关。心脏与血脉紧密相连；心气心阳推动血液通过脉管而布运全身，内人五脏六腑，外至四肢百骸，运行不息，并导致脉搏的跳动。另外，心对于血液的生成具有一定的作用。肺主气，“肺朝百脉”，肺气的敷布是心对血液推动作用的辅助。脾胃为“气血生化之源”；脾又主统血，血液在脉管内流行不致逸出脉外，有赖脾气的统摄。肝主疏泄，对于全身气机的调畅起着重要的作用，并促进血液营

2、运不休；肝又主藏血，能调节血流量。肾藏精，肾中精、气、阴、阳是人体各脏腑阴、阳的根本；且精可以化生血，肾精充足，则血有所充。Pulse-takingmeansthatthedoctoruseshisorherhandtopresscertainpartofthepatient'spulsetoexaminetheconditionsofthepulseanddiagnosedisease.Thepulseconditionsarecloselyrelatedtothevisceraandqiandblood.Thehea

6、odinthebody.脉诊Pulse-taking机理--脉为血之府，是气血运行的通道。气血的盛衰和运行状况，脉管的紧张度、弹性、粗细等，直接对脉象产生影响。因此，人体各脏腑功能活动及气、血、津液的盛衰和运行状况，都可以直接或间接地对脉象产生影响。当致病因素作用于人体，引起脏腑、气、血、津液的功能失常，脉象亦随之发生改变。故通过诊脉可以诊察疾病。Thevesselsaretheorganstoholdbloodandthepathwaysforqiandbloodtocirculate.Theconditionsand
