数据归一化处理，对数据进行一个标准化处理，将各个不同单位的变量，转换成无量纲的量(Data normalization, a standardization of data processing, will be different units of variables, into dimensionless quantities)

完成不带PML边界的2维声波介质波场正演(Forward modelling of the wave field in two-dimensional acoustic medium)

最小二乘法拟合进行n次多项式拟合，N用来控制拟合的次数，例如N=5时进行4次多项式拟合，还回的是拟合系数(Least squares fit polynomial n times, N is used to fit the number of control, e.g., N = 5 When quartic polynomial fitting, further back are fitting coefficients)
