摘　　要：利用积分方程方法讨论了一类抛物方程变系数非特征Cauchy问题,恢复了解的稳定性,得到了误差估计,并给出了数值算例.A noncharacteristic Cauchy problem for the parabolic equation with variable coefficient was investigated by the integral equation method. The stability of the solution was restored and the error estimate was also obtained. Finally, several numerical examples were presented to show the effectiveness of the proposed method.
