Numerical tests show that the proposed error estimation scheme can indicate the numerical errors of lbiem solution efficiently 数值算例显示，提出的误差估计方案能够有效地指示出真实的数值误差。
3.
Through careful analyses the author is able to conclude that the primary reason leading to niederkorn & ottino ' s incorrect conclusion is the numerical errors of velocity fields in their calculations and the errors of eccentricity in their experiments 分析表明，流场计算数值误差和实验偏心距误差是niederkorn & ottino得出不正确结论的主要原因。
