Is considered a problem of definition of characteristics of systems of queueing GI/G/1 with infinite turn, with final turn and losses. At present there are no exact methods of the analysis of such systems. In work, on the basis of twodimensional a diffusion approximations of fundamental processes of receipt and leaving of demands, are received analytical expressions for definition of the basic characteristics such queueing at level of average values and dispersions of distributions of times of receipt and service.
