Abstract: It is one of multiple creative researches of the American mathematician,Solomon W.Golomb,that Rubik's cube is taken as a model of quark confinement.In this paper,reviewing its concept and analyzing its drawbacks,an improved solution was proposed.The torsion forms of the Rubik's cube block were extended form 3 kinds (0°、+120°、-120°) to 5 kinds (0°、+120°、+240°、-120°、-240°),strengthening the expression of the model so as to represent all types of the mesons and the baryons formed by the quark confinement.
