摘　　要：通过对付里叶变换积分性质的运用研究，指出付里叶变换微分性质运用时容易产生的错误；并提出确定冲激项存在与否的新途径，进而说明付里叶变换积分性质运用的广泛性，尤其对时间有限函数更为突出。Through a research of the application of the integral properties of Fourier transform,this paper lists some mistakes easily caused in applying the differential properties of Fourier transform,puts forward a new method of determining the existence of an impulse response,and gives the facts of a universal application of the integral properties of Fourier transform,especially to limit function of time.
