摘要 通过引入最小误差函数,并将其应用于传统的热平衡积分法,改进的热平衡积分法和替换的热平衡积分法,在求解的过程中来确定近似多项式的次数,有效降低了事先给定多项式次数引起的误差,通过对计算结果的比较,得出此方法求得的结果要明显优于传统的热平衡积分法,进而实现精度的提高. A minimum error function is employed in Heat Balance Integral Method, Refined Integral Method and Mternative Refined Integral Method, and the exponent of the approximating polynomal is deter- mined during solution process. The new solutions are compared with the known solutions,which surpass the traditional HIMB. So, the accuracy of the solutions is improved
