【 摘 要 】

The paper describes methods for the analysis of cosmic rays mass composition and results for over a large time span. The data were obtained at Small Cherenkov array over 20 year period of continuous observation and 40 - years of observations at the main Yakutsk array. The experimental data indicates changes in the MC in the energy range 1016- 1018eV which confirmed by results obtained by other EAS arrays.
