摘要：
In potassium dihydrophosphate single crystals grown from aqueous solutions using the temperature lowering technique, the anomalous X-ray transmission (Borrmann effect) has been shown in experiment. The dependences of integral intensity of anomalously transmitted beam (T-i) and Laue reflected (R-i) one on the thickness t of the sample being studied have been found; these dependences made it possible to determine the dynamic approximation region for a "thick" crystal. Fot that region, the integral coefficients of dynamic absorption mu(i) and integral characteristic y(i) have been determined under dynamic approximation. The high sensitivity of the mu(i) parameter to the presence of coherent conjugation boundaries between the packages of growth layers is demonstrated.
