【Abstract】 Consider the asymptotic behavior of the solutions of nonlinear functional differential equation[q（t）x^2n-1（t）]^′+p（t）f[x（σ（t））]=e（t）.Some conditions to guarantee the solutions to be oscillatory are established.These results represent further improvements of the range of f（x） given by .更多还原
