lagrange piece wise interpolating function 分段lagrange插值函数
piece-wise quadratic Lyapunov function 分段二次Lyapunov函数
In order to describe this phenomenon, we characterize the overall dose-response relationship with a piecewise function that consists of a quadratic curve which is assumed to be U-shape curve and another quadratic curve at high dose levels.
因此我们这里用两个二次函数组成的分段函数构成了这种毒物兴奋效应现象的剂量—反应模型,其中较低剂量水平下的二次函数是U形曲线。
