提出了精确计算奇异积分的有效方法。奇异性在数值积分之前被移除,使用变量的改变、部分积分或两者的组合。变量的改变消除了x/sup -/spl alpha//,/spl alpha/ >类型的幂律奇点
Efficient schemes to accurately compute singular integrals are presented. The singularity is removed prior to numerical integration, using a change of variables, integration by parts, or a combination of both. A change of variables eliminates power-law singularities of the type x/sup -/spl alpha//, /spl alpha/ >
