摘要
本文从数值积分的角度出发,利用变量代换,将越流类井函数具有无穷型零点的被积函数变换成不具无穷型零点的被积函数,将广义积分截断成常义积分,并用其计算越流类井函数值,结果令人满意。
Started from numerical integral and change the integrand with infinite zero point of leaky well function into integrand without infinite zero point by the replacement of variables, and cut off generalized integral into normal integral and use it for calculating the function value of leaky well. The result is satisfactory.
