Inverse Fourier integral transform and integral formulas with infinite interval principal value along the real axis

CAI Dai-ping1,YIN Ji-wu2,LONG Shu-ming2(1.Department of Mechanical and Electrical Engineering, Ankang Vocational and Technical College,Ankang 725000,China; 2.School of Physics and Telecommunication Engineering, Shaanxi University of Technology,Hanzhong 723000,China)  
Fourier integral transform is an indispensable analysis tool in the engineering technology and scientific research,but inverse Fourier integral transform computation is very difficult.Research has found that the inverse Fourier integral transform can be transformed into closed path integral of the complex functions,using the residue theorem to complete calculation.The principal value integral formulas derived,can be used for inverse Fourier integral transform fast calculation.
