%X 作者对秩为2的无挠的李共形代数进行了刻画. 在这些代数中, 作者主要关注Virasoro{-}型李共形代数. 并且, 作者描述了一种特殊Virasoro{-}型李共形代数的共形导子、 秩为1的自由共形模和中心扩张.<br>In this paper, the torsion-free Lie conformal algebras of rank 2 are characterized. In these algebras, the authors pay more attention to the Virasoro-type Lie conformal algebras. Moreover, conformal derivations, free conformal modules of rank one and central extensions of a special Lie conformal algebra of Virasoro-type are determined.
