SAMPLE to set the sensitivity of ultrasonic devices

摘要

1.the sample u0434u043bu00a0 tuning sensitivity of ultrasonic devices consists of a block in the upper part of which is located u0440u0430u0431u043eu0447u0430u00a0 installation surface u0434u043bu00a0 conversion u0437u043eu0432u0430u0442u0435u043bu00a0 and reflector made inside the block, u043eu0442u043bu0438u0447u0430u044eu0449u0438u0439u0441u00a0 what lens are located on both sides and at the bottom of the specimen is cut, u0440u0430u0431u043eu0447u0430u00a0 power which parallel the upper working surface of moon.a height difference of height and depth of the cut is u043au043eu043du0442u0440u043eu043bu00a0, the size and the shape of the side surfaces are cut in such a manner that the lens from the p ole visibility reflected rays transducers mounted on the working surface of the cut, u0440u0430u0441u0441u0442u043eu00a0u043du0438u0435 from u043eu0442u0440u0430u0436u0430u0442u0435u043bu00a0 to cut u043eu043fu0440u0435u0434u0435u043bu00a0u044eu0442 of u0443u0441u043bu043eu0432u0438u00a0:;b2htg - s;where b is the u0440u0430u0441u0441u0442u043eu00a0u043du0438u0435 from u043eu0442u0440u0430u0436u0430u0442u0435u043bu00a0 prior to cleavage.;h is the depth of u043au043eu043du0442u0440u043eu043bu00a0;;is the angle of the beam u043fu0440u0435u043eu0431u0440u0430u0437u043eu0432u0430u0442u0435u043bu00a0;;s - arrow u043fu0440u0435u043eu0431u0440u0430u0437u043eu0432u0430u0442u0435u043b;2. model 1, u043eu0442u043bu0438u0447u0430u044eu0449u0438u0439u0441u00a0 so that the lens u043fu043bu043eu0441u043au043eu0434u043eu043du043du044bu0445 holes made in the form or in the form of lateral cylindrical holes, either in the form of their u0441u043eu0447u0435u0442u0430u043du0438u00a0.
