In this paper, the gray-white relation R ( ) = R ()°R is developed on the basis of a white relation R on Cartesian set X×Y and a gray relation R( ) on X{}×X. At the same time, the degree of gray-white is defined, and some theorems about relation R() and degree of gray-white of R() are given. The analyses of the inundation, whitening, equated values, interval on the degree of gray-white of R(), and some other results have provided a mathematical tool for analyzing and solving a kind of gray systems.
