中文摘要: 
Here presented are the definitions of $(c)$Riordan arrays and $(c)$Bell polynomials which are extensions of the classical Riordan arrays and Bell polynomials. The characterization of $(c)$Riordan arrays by means of the $A$ and $Z$sequences is given, which corresponds to a horizontal construction of a $(c)$Riordan array rather than its definition approach through column generating functions. There exists a onetoone correspondence between GegenbauerHumberttype polynomial sequences and the set of $(c)$Riordan arrays, which generates the sequence characterization of GegenbauerHumberttype polynomial sequences. The sequence characterization is applied to construct readily a $(c)$Riordan array. In addition, subgrouping of $(c)$Riordan arrays by using the characterizations is discussed. The $(c)$Bell polynomials and its identities by means of convolution families are also studied. Finally, the characterization of $(c)$Riordan arrays in terms of the convolution families and $(c)$Bell polynomials is presented.
