By studying the nonlinear functional equation with variable coefficients
x(g(t)) = P(t)x(t) + Q(t)
m 7i=1 | x(gki+M(t)) |?j sign x(gki+M(t))
the oscillation of the solution in this paper, we reached some new oscillation criterion. These criterion will expand or
improved some results of [1],[2],[4] and [6].
