考虑奇点位于区域内部的二维高分数阶奇异积分.利用Hadamard关于发散积分的有限部分的思想,给出了其Hadamard主值的表达式,并得到其可微性性质.
Two dimensional singular of the domain are considered. The formula egrals of high fractional order with the singularity of the Hadamard principal value is obtained by lies in the interior using the idea of Hadamard on the "finite part" of divergent integral,and the differentbility property is derived.
