Abstract: Is it possible to express the concept of life in mathematical terms? This is a challenge for life scientists. Meridian circulation is closely related to life. Life would end, if meridian circulation stops. Therefore, by analyzing the factors that influence the human meridian circulation, the mathematics of life may be derived: linking up capacity: U=f(a, b, c, ......); linking up efficiency: η=U_R/U_T, η<1. (a - vitality, b - reactive resistance,c - inducing factor, variation... etc., R - reality, T - theoretical.)

Key words: Chinese natural comprehension, meridian science, liquid media contained in the apposite membrane structure, regulation of low resistance passing, efficiency of meridian linking up

摘要： 生命能否以数学表达，这是生命科学家感兴趣的难题。经络循行是与生命共存的：经络循行停止，生命则终结。因此，可以通过表述人体经络贯通能力的变量，用数学公式表达生命。贯通能力U是影响贯通因素——生命活力a，反应阻力b，诱发因素c，变异等的函数。而贯通效率η是实际贯通程度U_R，与理论贯通程度U_T之比。
