说明：  抛物线法求解 方程的构造方法:给出[0,1]区间上的随机数(服从均匀分布)作为方程的根p*. 设你的班级数为a3,学号的后两位数分别为a2与a1,从而得到你的三次方程 例如:你的31班的12号,则你的方程是21x3+60x2+2x+a0=0的形式. 方程中的系数a0由你得到的根p*来确定.
(Constructor method for solving parabolic equations: given [0,1] random number (uniformly distributed) as the root of the equation p* Let your a3 interval for the number of classes, and after a two-digit student number were a2 and a1, so get your cubic equation example: Your 31 classes of the 12th, then your form of the equation is 21x3+60x2+2x+a0 = 0 equation coefficients a0 to you get to determine the root of p*.)
