论脉象与“位、数、形、势”的关系

On the relationships between pulse tracing and position,rate,shape and force attributes

"位、数、形、势"是晚清医家周学海提出的正脉之纲领,是脉象的4个关键属性,其与脉象的本质都是"象",分属不同层次。"位、数、形、势"与脉象之间有着复杂的关系,除4者之间的从属关系、动静关系外,与脉象之间还存在着双重关系。

Four key attributes, position, rate, shape and force, are programs of pulse tracing put forward by ZHOU Xue-hai, a medical practitioner in late Qing dynasty. The essences of four key attributes are ＇images＇ of different levels. There are complex relationships between pulse tracing and position, rate, shape and force attributes, which include not only subordinate relationship and static-dynamic relationship between four attributes but double relationship between four attributes and pulse tracing.
