以随机微分方程组(1)作为地极移动(钱德勒摆动)的数学模型,求出了(1)的解。此解是二维的正态、平稳、马尔科夫随机过程,它具有遍历性.找到了它的转移概率密度和相关函数.通过对相关函数的研究,如果取ω=5.274,则钱德勘周期重合于强相关周期2π/ω;此外,还发现了另一个周期,即独立性周期π/ω.最后,研究了地极移动模型的最佳预测公式和预测误差. Taking the stochastic differential equation (1) as the mathematical model of the pole-to-pole movement (Chandler swing), the solution of (1) is obtained. This solution is a two-dimensional normal, stationary, Markov random process, which has ergodicity and finds its transfer probability density and correlation function.By studying the correlation function, if we take ω = 5.274, Period coincides with strong correlation period 2π / ω, and another period is found, ie independence period π / ω.Finally, we study the best prediction formula and prediction error of the moving model of the earth.
