摘要：

The work deals with the theoretical wave-optical diffraction description of X-ray phase image peculiarities of non-crystalline objects in the Phase Dispersion Imaging technique. The equation for diffracted beam amplitude E-k(x) coincides with the ones obtained by other authors, The equation for transmitted beam amplitude E-0(x) contains the additional term with the field derivative partial derivative E-0/partial derivative x. The comparison of computer simulation of the X-ray intensity distribution in the image plane of the test object with the experimental results demonstrates that the theory is satisfactory.
