讨论了MARMA模型的平稳性条件和自相关函数。
The stationary conditions and autocorrelation function of the MARMA process are investigated.
在此较弱的条件下，本文不仅给出了平稳分布存在与唯一性的简洁证明，而且还给出了平稳分布的计算方法。
Under this weak condition, this paper gives not only a concise proof of the existence and uniqueness of the stationary distribution, and also the the computation method of the stationary distribution.
仿真结果还表明，车辆系统在弹性轨道条件下的运行平稳性优于刚性轨道条件下的运行平稳性。
The simulation results also show that the running stability of the vehicle system under the resilient track conditions is better than that under the rigid track conditions.
