	Abstract:  
	Zero-difference balanced(ZDB) functions were  introducedby Ding in connection with  construction of optimal constant composition codes and optimal and perfect difference systems of sets. In this talk, the zero-difference balanced function is generalized to be the generalized zero-difference balanced function(G-ZDB), several classes of generalized zero-difference balanced functions are constructed.And then based on G-ZDB functions,  some Constant Composition Codes or Difference Systems of Sets are obtained.
