An artificial random disturbance is carried out for some seismological observation data in the allowance range of seismological observationalerror with random disturbance method.
采用随机干扰方法，在地震观测误差容许值范围内，对地震观测资料进行人为随机干扰。

Using the statistically optimal inversion method 50 sets of simulation microwave radiation data are retrieved. The influence of observationalerror on the inversion accuracy is discussed.
运用统计最优反演方法对50组模拟的微波辐射资料进行了反演，并讨论了观测误差对反演精度的影响。
