摘　　要：本文利用单裂纹扭转的位错型解答,使用有限部积分的概念和方法,最后将含有单根水平裂纹的柱体扭转问题归为解一个强奇性积分方程,并为其建立了数值求解方法,文末作了若干数值例子的计算,结果令人满意.From the dislocation type solution of the torsion of single crack, by using the concept of finite part integrals, we reduc; the torsion problem of cylinder with a single crack into an integral jquation with strong singularity. The numerical method is also obtained and several numerical examples are calculated successfully at the end of this paper.
