摘要

the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 to control the tightness of hollow products and u043fu043eu0437u0432u043eu043bu00a0u0435u0442 increase sensitivity in the control of small u0442u0435u0447u0435u0439. the first cavity u0434u0438u0444u043cu0430u043du043eu043cu0435u0442u0440u0430 communicate with the product and the first additional capacity, the second model of the second additional capacity. create the test pressure in the product, both supplementary and reference u0435u043cu043au043eu0441u0442u00a0u0445.in u0432u0440u0435u043cu00a0 extracts u0440u0430u0437u043eu0431u0449u0430u044eu0442 cavity u0434u0438u0444u043cu0430u043du043eu043cu0435u0442u0440u0430 with product and the reference intensity and reduce the amount of additional storage capacity in equal amounts. u043eu043fu0440u0435u0434u0435u043bu00a0u044eu0442 change u0434u0430u0432u043bu0435u043du0438u00a0 in u043fu043eu043bu043eu0441u0442u00a0u0445 u0434u0438u0444u043cu0430u043du043eu043cu0435u0442u0440u0430, which u0441u0443u0434u00a0u0442 degree of u043du0435u0433u0435u0440u043cu0435u0442u0438u0447u043du043eu0441u0442u0438 u0438u0437u0434u0435u043bu0438u00a0. 1 il.
