摘要
许多文献认为|X|^(-1)的傅里叶变换象函数是(?),这是不正确的。本文用积分的求和定义估计了此象函数(积分),并在两种不同的积分主值定义下计算出此象函数为(?),其中C为欧拉常数,常数D与ω无关但依赖于积分主值的定义。
It is incorrect that the Fourier transform (integral) of the function |x|^(-1) is
(?) as many literatures have given. Two methods of integration show the
Fourier transform of |x|^(-1) (?), where C is Euler's constant,
constant D is independent of ω and is dependent on the definitions of the princi-
pal value of integral.
