摘要

the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 to measurement technique and can be used to control the hardness of the piston rings for internal u0441u0433u043eu0440u0430u043du0438u00a0 engines (ice). purpose u0438u0437u043eu0431u0440u0435u0442u0435u043du0438u00a0 u00a0u0432u043bu00a0u0435u0442u0441u00a0 improved accuracy and simplify the structure. controlled piston ring 4 is installed in the ring u043eu0431u0435u0447u0430u0439u043au0443 1 of the optically active material placed between the u043fu043eu043bu00a0u0440u043eu0438u0434u0430u043cu0438 3 and covering the parallel pooch one of the world.the resulting interference compared with the standard and the largest deviations from standard fringe size of u043eu043fu0440u0435u0434u0435u043bu00a0u044eu0442 u044du043fu044eu0440u0443 radial u0434u0430u0432u043bu0435u043du0438u00a0 piston ring in the cylinder wall of ice. 2).
