‎This paper deals with the singular Sturm-Liouville expressions‎
‎\ell y =‎ -‎y''+q(x)y=\lambda y‎
‎on a finite interval‎, ‎where the potential function $q$ is real and‎
‎has a singularity inside the interval‎.
‎Using the asymptotic estimates of a‎
‎spectral fundamental system of solutions of Sturm-Liouville‎
‎equation‎, ‎the asymptotic form of the solution of the‎
‎equation (0.1) and the eigenvalues are obtained‎, ‎and proves the stability of the‎
‎solution of the inverse spectral problem.
