本程序可进行一维非线性曲线拟合，并绘制拟合后的曲线图。-This procedure can be one-dimensional non-linear curve fitting, and after drawing curve fitting.

对于已知少量的点，使用多项式对其曲线进行近似拟合，从而预测未知的点的函数值。-For a small number of the known points, its curve is approximated using a polynomial fit to the prediction function value of the unknown point.
