Abstract
In this paper,some new concepts and properties abou t affine sets and affine transformations are proposed.For affine sets,the concep t of maximal affinely independent quantities is defined,and we point out the rel ationship between the maximal linearly independent quantities and the maximal af f inely independent quantities in the case of trivial and nontrivial affine sets .For affine transformations,we find that they can be determined uniquely by thei r functions on one affine basis.
