Some properties of inverse self-conjugate operator and inverse involutive transformation,the relations between them and orthogonal transformation are inverstigated.

When the noise-free dynamic system does not meet any shrink condition,but after some topological conjugate transformation it meets a shrink condition, in such case we prove that under some moment condition on the noise the corresponding autoregressive model has an unique stationary solution, which is geometrically ergotic.
若原系统不具有任何压缩性质,但是它的某种拓扑共轭变换后的系统满足一定的压缩性质,本文指出,当噪声适当小时,相应的带噪声的动态系统将有唯一的平稳解,而且是几何遍历的。
