摘　　要：针对轴对称热传导问题边界元分析中奇异积分的处理提出了一种新的统一处理方法,在此基础上通过数值试验进一步给出了一种更为简洁的处理方法。数值计算及应用结果表明,本文提出的方法计算工作量小,便于形成具有良好结构性能和高效率的通用分析程序。In this paper, an new and unite method about singular integral of boundary element ana-lysis for steady axisymmetric potential problem is presented. On this basis, an new simple method to solve above problem is developed. The results of numenrial analysis and application show that the method developed by author is successful.
