MEMS陀螺随机误差建模算法研究。MEMS陀螺精度较低，随机漂移较大，严重影响系统的性能。对MEMS陀螺随机误差进行了时间序列分析，并建立了ARMA模型。使用MATLAB计算所选模型参数建立随机误差的系统方程，采用经典卡尔曼滤波器验证了在静态条件下，滤波后的信号标准差为滤波前的3．88％。针对动态条件下，常规卡尔曼滤波器滤波效果下降的问题，推导并设计了渐消卡尔曼滤波器。仿真结果表明，渐消卡尔曼滤波器能显著改善动态条件下的滤波效果，并且滤波精度较高。

经典的潮汐分析方法，在引用这一分析原理时，首先把实测潮位记录中的各分潮（如太阴分潮系、太阳分潮系等）分离出来，再进行调和分析。求出每一分潮的振幅和位相角，再经天文因素订正后，即得该分潮的调和常数。用潮汐调和分析可推算一定期间内的潮汐变化和分析该区的潮汐性质。(Classical tidal analysis methods, in applying the principle of this analysis, the first record of the measured tide in the sub-tidal (such as the Department of Taiyin tide, solar tide line, etc.) separated from the harmonic analysis further. Calculated for each sub-wave amplitude and phase angle, and then revised by the astronomical factors that have to reconcile the sub-tidal constants. Using tidal harmonic analysis can be projected a certain period of time the tides change and analysis of the tidal nature of the area.)
