标题： The rotation curve and mass-distribution in highly flattened galaxies

摘要： 提出了一种新方法，可通过任意光滑的角速度分布，借助两次简单的数值积分来重建有限半径的银河盘表面密度分布。 证明了在旋转曲线解析延拓到盘的隐藏（非辐射）部分的过程中，盘的质量和半径存在上限。 显示英文摘要

摘要： A new method is developed which permits the reconstruction of the surface-density distribution in the galactic disk of finite radius from an arbitrary smooth distribution of the angular velocity via two simple quadratures. The existence of upper limits for disk's mass and radius during the analytic continuation of rotation curves into the hidden (non-radiating) part of the disk is demonstrated.
