Scientific paper

The formation of the spatial structure of DQ Her 1934 and HR Del 1967 shells is considered. It has been shown that polar caps are formed due to the influence of the satellite on the angular distribution of mass shell depths. The formation of the equatorial ring is caused by the interaction of the nova main shell and the circumstellar shell. The ratio of mass shell depths in the equatorial ring to the one in polar caps is 1.13 for DQ Her and 2.7 for HR Del. The ratio of maximum density in the equatorial ring and in the polar caps is about 3 for DQ Her and about 70 for HR Del.
