摘要：
The problem of measurement of flaw dimensions in diamond wire-drawing dies is discussed. An analytical expression for the modulation depth of diffraction rings as a function of the flaw dimension is given, and analytical calculations are compared to numerical calculations for various types of flaws. Changes in the symmetry of the diffraction pattern due to a local flaw on the hole surface are described.
