摘要该文将超松弛重叠及非重叠区域分裂法与矢量有限元方法、边界积分方程法相结合对三维电大尺寸开口腔体的电磁散射特性进行分析。

If the pattern has a low rate of convergence, the time of the human and machines will be wasted and the answer are not surely attainable.So,we must look for the patterns with the high rate of convergence or try to settle some parameters of the iteration patterns (for instance the overrelaxation parameter of SOR iterative method).

本文第二章针对AOR迭代法考察了当线性方程组的系数矩阵A为(1，1)相容次序矩阵且其Jacobi特征值为纯虚数或零时的迭代收敛范围，最优参数(即最优松弛因子和最优加速因子)及与之相应的谱半径，并将此最优谱半径与相应的SOR的进行比较，定量的给出在不同条件下，AOR和SOR迭代法各有其优越性，从而圆满的解决了在这两种迭代法之间如何适当的选择最佳迭代法的问题。

结论一次性使用输液器连接高分子导管进行清洁灌肠法效果明显优于一次性使用肛门管清洁灌肠法，是一种较理想的灌肠方法，尤其对于肛门括约肌松弛的老年便秘病人。

objectiveto determine the effect of the furlow's method combined with bilateral relaxant incision on reconstruction of the soft palate fissure after palatorrhaphy.methods8 patients, who suffered from soft palate fissure after palatorrhaphy, were operated with the furlow's method combined with bilateral sufficient relaxant incision from 2003 to 2007.resultsall patients' wound healed well without oronasal fistulas or palate fissure.

目的：探讨采用furlow法整复腭裂术后软腭复裂的效果。方法：选2003年～2007年间我科收治的腭裂术后复裂患者，对其中8例软腭复裂的患者采用furlow法联合双侧松弛切口进行修复。结果：8例患者伤口均愈合良好，未见腭部穿孔或伤口裂开。

Follow-up 1 month later, the patients had good function of velopharyngeal closure.conclusionthis technique is useful to repair soft palate fissure after palatorrhaphy and reconstruct the palatopharyngeal function.
