Scientific paper

Between December 1980 and March 1984, photoelectric observations of SZ Lyn were made on 15 nights and were recorded 19 maxima times. Combining with those published, we now have a total of 139 times of maxima. Applying a second-order least squares reduction to this data, it is found that the period of SZ Syn is definitely increasing at a rate of 0.165 seconds per 100 years or (6.32 + or - 0.62) x 10 to the -12th d/period.
