| 摘 要： | 针对小样本情形下用传统方法对参数进行估计难以得到满意结果，在采用矩法由历史数据估计先验分布参数的基础上，将先验信息和后验信息相对化，采用动态修正Bayes估计法，对零均值正态分布的方差进行估计，建立了动态递推模型．并用蒙特卡罗法进行仿真模拟，结果表明，所采用的方法提高了估计精度．

| Abstract: | In consideration of the relativity of prior and the posterior information, the method of dynamic revised Bayesian was introduced to estimate the variance of normal distribution with zero mean. A model of dynamic recurrence estimate was developed. The results of monte carlo simulation showed that the method improved the estimated accuracy, and it was practical. |
