[en] The work of JINR at Dubna, the first international scientific centre of socialist countries, is focused on studies in theoretical physics, high energy physics, nuclear physics, and low energy physics. Results are described obtained so far in the above fields as well as computer technology and data processing. JINR is also a centre for accelerator technology work. The U-300 three-meter cyclotron and the U-200 two-meter isochronous cyclotron were installed and the U-400 four-meter cyclotron is being built. The experience of JINR shows that the institute has become an educational facility for scientists and specialists from the participating countries. (J.P.)
