In this paper, a random coefficient functional autoregressive model is proposed and the sufficient condition of the geometric ergodicity is obtained.

提出了随机系数泛函自回归模型，得到了几何遍历性的充分条件。

During the modeling for functional gradient materials, one needs to modify continually the coefficient of material composition functions to satisfy the design requirements.

功能梯度材料实体建模过程中，需要对材料成分方程系数进行不断修改以满足设计要求。
