When they turned these measurements into a series of waves using a mathematical trick called a Fourier transform, the waves increased in magnitude as their frequency decreased.
当他们把测量结果通过傅立叶变换分解成一组波时，这组波随着频率减小而增幅巨大。

A series of primary pictures are made by optical Fourier transformation and convolution operation.
这种方法是通过对光学傅氏变换所获得的一系列初始图像进行卷积。

In this paper by using the property of Fourierseries a compound series consisting of trigonometric series and power series is established.
