| 摘 要： | 系统辨识在系统工程、自动化及控制等领域都起着非常重要的作用。分析了单输入多输出（SIMO）系统的辨识问题，讨论了用最小二乘方法所给出的估计参数的统计特性，从统计学的角度证明了估计参数是否具有无偏性以及相合性等性质，另外还提出了一个关于有偏估计的猜想。

| Abstract: | The identification problem in a SIMO system is considered and the statistical properties of the estimated parameters given by the least square method is discussed, Whether the estimation is unbiased and consistent have been proved from the statistics point of view. A conjecture has also been presented. |
