完成多项式的运算，可以输入完整的多项式，包含括号，加减乘除求余等-complete polynomial arithmetic, can be imported complete polynomial, includes brackets for the arithmetic, etc. I

实现两个多项式之间的运算：加法和乘法（输入多项式系数）-Between two polynomials operations: addition and multiplication (input polynomial coefficients)

Delphi 多点曲线光滑拟和，实现1次多项式最小二乘、2次多项式最小二乘，最终显示实验值、a+bx+cx^2拟合、ae^(b/x)拟合值，以控制台窗口方式显示出运算结果。-Delphi more smooth curve fitting, the realization of 1 polynomial least squares, 2 polynomial least squares, the final show experimental values, a+bx+cx^2 fitting,
