根据ANSYS分析得到位移时间数据点后，可用MATLAB拟合其衰减曲线(ANSYS analysis based on data obtained after displacement time point, the attenuation curve fitting is available MATLAB)

OSCAR is an optical FFT code used to calculate the steady state optical eld circulating in Fabry Perot cavities. The code can integrate non-sperical mirrors and any arbitrary input elds. Recent applications for OSCAR have been: calculation of thermal lensing eect and calculation of diraction loss and cavity eigen modes for mesa beams. One great advantage of OSCAR is the simplicity and exibility of the code, everyone with only minimal knowl- edge of Matlab can easily modied OSCAR code to suit specc purposes.

这是一个超级方程,运用MATLAB进行解得,直接设置参数,即可得到方程解.(This is a super-equations, the use of MATLAB to solve for, directly set the parameters, equations can be obtained.)

运用粒子群优化算法对ARMA(p,q)模型的阶数进行优化是可行的，且利用优化后的ARMA模型对航空发电机状态趋势进行分析的结果十分准确，与原始数据所表现出的航空发电机状态变化趋势基本一致。经计算，此时分析结果的平均相对误差较小，仅为1.38 ，与优化前构建的ARMA模型相比，平均相对误差降低0.23个百分点，优化效果明显。(Using particle swarm optimization algorithm to optimize the order of the ARMA (p, q) model is feasible, and the use of the results of the ARMA model optimized air generator status trends analysis is very accurate, and the raw data showed aviation the generator status consistent trend. Calculated analysis of the results, the average relative error is small, only 1.38 , compared with the the ARMA model built before optimization, average relative error is reduced by 0.23 percentage points, to optimize the effect is obvious.)
