摘　　要：通过分析三次多项式型迭代方程的特征根,并利用其特征解所描述的通解一般迭代式,作者在新的特征分布下给出了连续解的若干性质.The third order polynomial-like iterative equation is discussed. By analyzing its characteristic roots and applying the general iteration formula of solutions, which is described with characteristic solutions, some properties of continuous solutions in some new characteristic distributions are obtained.
