In order to control the composition and microstructure of corrosion-resistant aluminum coatings, a layer of pre-coating was deposited on Q235 steel surface by magnetron sputtering, and then corrosion-resistant aluminum coating with a certain thicknes

Many available published times of light minima of the active binary system UV Psc have been collected and analyzed using a new method proposed by Kalimeris et al. (1994). Similar to what was seen in other RS CVn-type binaries, the orbital period of U

Many available published times of light minima of the late-type binary system ER Vul have been compiled and analyzed using a new method proposed by Kalimeris et al. (1994). It was shown that the orbital period of the system oscillation with a period

New two-colour observations of AH Tau in 1986 are given. The light curves changed appreciably since 1973, the new curves are symmetrical. A photometric solution is obtained using the Wilson-Devinney method. It has a degree of overcontact of 9.1%. The

Photoelectric photometric observations of DF Hydrae were made in 1985, including two primary and two secondary minimum times. The period was found to be varying and a new epoch formula is derived. An extensive search for the mass ratio q was carried

We give a new method of determining the absolute dimensions of a contact binary based on minimum light times and applied it to the system AW UMa. This method is independent of spectroscopic data. Our results show that Rensing's model for correcting f
