模态参数的时域识别方法，即在时间域内识别试验结构模态参数。(Time-domain modal parameter identification method, that is, the structure in time domain modal parameter identification experiments.)

建立现行规划模型，求最优解（最大值或最小值）。(Establish the current planning model, find the optimal solution (maximum or minimum value).)

成像处理一般包括三个步骤：1、距离向脉冲压缩，对一个合成孔径内的每个回波脉冲均进行压缩；2、距离徙动矫正，把属于同一点目标的脉冲校正到等距离线上、3、方位向脉冲压缩。(Imaging process generally comprises three steps: a distance to the pulse compression of echo pulses each have an inner aperture compression 2, range migration correction, the pulses belonging to the same point in the correction target line equidistant , 3, azimuth compression to pulse.)

程序1：周期信号（方波）的展开 程序2：用图形表示DSB调制波形及其包络线 程序3：通过傅里叶变换找出被随机信号淹没的信号频率 程序4：DSB-AM 双边带幅度调制和解调 程序5：AM调制和解调(Procedure 1: periodic signal (square wave) Program 2: graph DSB modulation waveform and its envelope Application 3: through the Fourier transform to find out the submerged by random signal signal frequency Program 4: DSB- AM double sideband amplitude modulation and demodulation Program 5: AM modulation and demodulation)

说明：  seir模型模拟传染病 人在康复以后产生了抗体就不会再得病。不同于SIS模型，我们在模型中引入康复者(The Recovered)，用 [公式] 表示，并满足总人数 [公式] 。这个时候就是SIR模型。一旦变为康复者，就不会再传染，即在概率传递过程中，一旦变为康复者，就没有概率再次转移为感染者或者易感者。我们假设感染者变为康复者的概率为我们来看下SIR模型的微分方程(SEIR model simulating infectious diseases)
