物化分析的数学工具是可拓集合,可拓集合是用关联函数来刻划的。本文试图建立一种新的关联函数构造法。使关联函数的取值范围充满整个实轴,以拓广物元分析应用范围。

The maths tool of matter element analysis is extension set. Extension set is described by dependent function.This article tries to bulid a new kind of construction of dependent function.It will make a dependent function in range of the measure full of the number axis of real number.And the range of apply can be wided.
