Influence on expanding the scale of Introducing high-efficient new machinery In the national economy Is extremely significant because there are many examples Illustrating that new designed machines, equipment, devices. materials, technologies are not mastered for a long time or are mastered In very little volumes. Programs fpr splylng maJpr sc!ent!tlc-techno!pglcal prpblems. are elaborated for Individual problems of major national economic significance and associated with the development of principally new technologies and types of machinery, and raising them to practical realization. as well as with the development of scientific research and technical development along the most prospective directions of science and technology for carrying out work In anticipation of the forthcoming period. These programs lack the aim of wide-scale Introduction of new machinery and technologies. They are fulfilled mainly up to the beginning of mastering the novelty In production. and they are restricted frequently by research and developments required for the selection and scientific substantiation of optimum ways of solving the problem and determining the future work, by experimental and experimental-Industrial testing, manufacturing and al !-round Investigation of the demonstration samples and objects. The programs for solving scientific-technological problems render no direct effect on the current economy but they create our future scientific-technical and Industrial bases. It Is necessary to note that targetS and T programs may comprise also Individual assignments for expanding research and developments for work In anticipation of the near future. The content of the final targets of the at 1-unlon scientific-technical programs can be clearly Illustrated by the example of programs realized for l981-1985. The State five-year plan of economic and social development of the USSR tor the XI five-year period comprises 170 approved. all-union S and T programs. They have been selected as a result of thorough analysts of hundreds of maJor scientific-technical problems,
