Description

Известные приборы дл  определени  интенсивности ультразвука, основанные на использовании эффекта нагревани  ультразвуком звукопоглощающей жидкости и содержащие в качестве индикаторов термометры или пьезометрические датчики, имеют невысокую точность измерени , св занную либо с неоднородностью температурного пол , вследствие поперечной неоднородности ультразвукового пучка, либо с больщой теплоотдачей в утолщенные стенки прибора.The known devices for determining the intensity of ultrasound, based on the use of the effect of ultrasonic heating of a sound-absorbing liquid and containing thermometers or piezometric sensors as indicators, have a low measurement accuracy associated either with the heterogeneity of the temperature field, due to the transverse inhomogeneity of the ultrasonic beam, or with a large heat transfer in thickened walls of the device.

Предлагаетс  прибор дл  измерени  абсолютной интенсивности ультразвука , основанный на использовании теплового расщирени  жидкостей , нагревающихс  при поглощении ультразвукового излучени , в котором , в отличие от известных приборов, использующих тот же эффект, определение интенсивности производитс  по скорости подъема нагреваемой жидкости в капилл ре между двум  фиксированными делени ми щкалы. С этой целью прибор содержит вакуумно-теплоизолированный сосуд (типа Дьюара), заполненный звукопоглощающей жидкостью, который имеет отверстие дл  приема ультразвукового пучка, закрытое пластинкой , толщиной меньщей или равной длине полуволны ультразвука, и сменные капилл рные трубки, в которых определ етс  скорость подъема нагреваемой жидкости.A device for measuring the absolute intensity of ultrasound is proposed, based on the use of thermal expansion of liquids heated by absorption of ultrasonic radiation, in which, unlike the known devices using the same effect, intensity is determined by the rate of rise of the heated liquid in the capillary between two fixed divisions. mi sckaly To this end, the device contains a vacuum heat-insulated vessel (of the Dewar type) filled with sound-absorbing liquid, which has an opening for receiving an ultrasonic beam, covered with a plate with a thickness less than or equal to the half-wavelength of ultrasound, and replaceable capillary tubes in which the ascent rate is determined. fluid.

Прибор дл  определени  интенсивности ультразвука (см. чертеж), состоит из стекл нного сосуда J с тонкими двойными стенками, давление между которыми равно мм рт. ст. Рогообразна  форма сосуда выбрана дл  более полного поглош-стш  ультразвукового пучка, поступающего через круглую стекл нную пластину 2, плотно прижимаемую сменным колпачком 3 к стенкам сосуда дл  предотвращени  вытекани  жидкости . Через стекл нное горлыщко 4 в сосуд ввод тс  взаимозамен емые капилл рлые трубки 5 различного внутреннего диаметра. Шкала 6 служит /:-.; определени  скорости подъема нагреваемой жидкости по капилл ру .;;A device for determining the intensity of ultrasound (see drawing), consists of a glass vessel J with thin double walls, the pressure between which is equal to mm Hg. Art. The vessel's horn-shaped shape is selected for a more complete, continuous ultrasound beam, which flows through a circular glass plate 2 tightly pressed by a replaceable cap 3 to the vessel walls to prevent liquid from leaking out. Through the glass neck 4 interchangeable capillary tubes 5 of different internal diameter are introduced into the vessel. Scale 6 serves /: - .; determine the rate of ascent of the heated fluid through the capillary ;;;
