Abstract: In this paper, the property of orientation distribution function composed of second and fourth legendre polynomials was studied. It was pointed that this function can he used to describe four kinds of orientation distribution models. Corresponding to the four models, four regions of order parameters and were given. The orientation distribution polar graphs were observed when the order parameters were changing.

Key words: Two-dimensional condensed phase, Order parameters, Orientation distribution function, Orientation distribution polar graph
