The empirical mode decomposition method is introduced to extract the trend item of gyro's drift, but the local mean estimation isn't precision and the end effects exist in the conventional EMD method. The two-tap adaptive time-varying filter and the adaptive border estimation are used to modify the EMD. After the trend extraction, the method of time series analysis is used to make the autoregressive moving average model for stationary time series.

根据陀螺漂移的特性，提出采用经验模分解的方法对其趋势项进行提取，但传统的经验模分解方法存在局部均值估值不准，插值过程存在端点效应的问题，因此，本文又引入二拍自适应滤波及自适应边界估值来对原方法加以改进；在成功提取趋势项后，通过采用时间序列的分析方法，建立了陀螺漂移平稳时间序列的自回归滑动平均模型；并得出陀螺漂移模型可近似为常值加一阶马尔可夫过程这样一个结论。

Most microorganisms, such as bacteria and fungi, are decomposers; they break down, or catabolize, the organic materials produced by plants and animals and make the nutrients contained in them available to successive generations of living things.

大部分微生物，例如细菌和真菌等，都是腐生物，可分解或分解代谢动植物所产生的有机物，而且还可把体内的养料供给生物世世代代享用。在某种程度上，我们可以把生物清理法看作是这些生物自然变化的一种延伸。
