【 摘 要 】

WeperformedspectroscopicobservationsofCometTabur(C/1996Q1)from1996September14toOctober16,on9nights.Thegas-to-dustratiowasdeterminedforC/Tabur,andcomparedwiththatofCometLiller(C/1988A1),whoseorbitalelementsarequitesimilartothoseofC/Tabur.Thegas-to-dustmassratioobtainedforC/TaburisoneorderlargerthanC/Liller.Becausethissimilarityoftheorbitsindicatesasplittingofthesecometsinthepast,theobtaineddifferenceinthegas-to-dustmassratioshouldbeduetoaninhomogeneityofthecometarynucleus.
