中文说明： 使用大量的有限元法求解偏微分方程，连续相位调制信号(CPM)产生，分析了该信号的时域、频域、倒谱，循环谱等,从先验概率中采样，计算权重，用谱方法计算流体力学一些流动现象的整体稳定性,用平面波展开法计算二维声子晶体带隙。
English Description：
Using a large number of the finite element method for solving partial differential equations, continuous phase modulation (CPM), analyzes the signal in time domain, frequency domain, cepstrum, cyclic spectrum, sampling from the prior probability, calculate weights method is used to calculate overall stability of fluid flow phenomena, using the plane wave expansion method for calculation of band gap of two-dimensional phononic crystals.
