Basically, the traditional way may involve method of time series, multi-linear regression and the Fourierexpansion, etc.
传统方法中主要有时间序列法、多元线性回归法及傅立叶展开法等。

The method approaches the unknown integrating factor with FourierExpansion and deducts a kind of computer simulation formula which is similar to the Adams arithmetic.
该方法利用傅立叶展开来逼近未知的积分项，导出一种类似于阿达姆斯方法的计算机仿真计算公式。

Basedg on Fourier optical principle, the imaging property of grating illuminated by expansion source is analysed in this paper. Hence an innovative grating imaging displacement sensor is designed.
