| 摘 要： | 针对传统时域傅立叶变换方法的缺点,笔者首次提出了一种从角域到倒角域的傅立叶变换方法,并推导了该变换的理论公式.该变换从角度域来考察信号的信息及其特征,反映了信号的一些空间性质,可以很方便的解决旋转机械的非稳态问题.

| Abstract: | According to the shortcomings of traditional time domain Fourier transform,one new method of angle domain Fourier transform is put forward at first time,and theoretical formulas are deduced.This transform can research the information and character of signal from angle domain,especially some space character.The nonstationary problem of rotary mechanism can be resolved easily with this transform. |
