reverse curve

A large amount of computation results indicate that the reverse generating operation of the second order differential model based on first-order accumulated generating operation can fit the a-N curve at high precision. The proposed method can be extended to other engineering fields satisfactorily.

大量计算表明，由一次累加生成值建立二阶微分方程模型后再还原的模型可以高精度拟合aN试验曲线，可望在工程上推广应用。
