| 摘 要： | 弹性函数是研究当自变量有微弱变化时 ,函数的相对变化率 .本文构造一条初始弹性直线 ,弹性函数就是函数的切线斜率与初始弹性直线斜率之比 ;也是函数在弹性支点的微分与初始弹性直线在弹性支点的增量之比 .

| Abstract: | Elastic function is the research into the relative change rate of the function where the independent variable has a slight change. This paper constructs an initial elastic straight line. The elastic function is the ratio between the tangent slop of the function and the initial straight line slope; is also the ratio between the differential of the function at the elastic fulcrum and the increment of the initial elastic straight line at the elastic fulcrum. |

| Keywords: | elastic function initial elastic straight line elastic fulcrum elastic angle geometric interpretation |
