2-Cocycles of Original Deformative Schr\"{o}dinger-Virasoro Algebras
  Both original and twisted Schr\"{o}dinger-Virasoro algebras also their deformations were introduced and investigated in a series of papers by Henkel, Roger and Unterberger. In the present paper we aim to determine the 2-cocycles of original deformative Schr\"{o}dinger-Virasoro algebras.
