Description
Известны способы абсолютного намерени интенсивности ультразвука термическим приемником, теплоизолированным от окружающе среды, ио скорости его нагрева. Известны также способы абсолютного измерени интенсивности ультразвука термическим приемником, не теплоизолированным от окружающей среды, при котором интенсивность измер етс по установившейс температуре теплоперепада.Methods of absolute intent of ultrasound intensity by a thermal receiver, insulated from the environment, and its heating rate are known. Methods are also known for absolute measurement of the ultrasound intensity by a thermal receiver not thermally insulated from the environment, in which the intensity is measured at the steady-state temperature of the heat output.
Недостатком указанных способов вл етс трудоемкость их, ввиду сложности определени коэффициента теплопередачи, а также сложность конструкций, примен емых дл осуществлени способов.The disadvantage of these methods is their laboriousness, due to the complexity of determining the heat transfer coefficient, as well as the complexity of the structures used to implement the methods.
Предлагаемый способ значительно ироще известных. Это достигаетс возможностью применени дл абсолютных измерений обычных миниатюрных (не калориметрических) термических приемников беч теплоизол ции, используемых обычно дл относительных измерений и отличающихс простотой конструкции.The proposed method is much better known. This is achieved by the use of absolute thermal measurements for absolute measurements of conventional miniature (non-calorimetric) thermal receivers, heat insulation, commonly used for relative measurements and characterized by simplicity of design.
Кроме того, предлагаемый способ имеет то преимущество, что не требует дл своего осуществлени измерени коэффициента теплоотдачи . Сущность способа состоит в том, что измер ют скорость нагрева поглотител в начальный момент облучени при величине температурного перепада между поглотителем и окружающей средой, близкой к нулю.In addition, the proposed method has the advantage that it does not require a heat transfer coefficient to measure. The essence of the method is that the heating rate of the absorber is measured at the initial moment of irradiation with the temperature difference between the absorber and the environment close to zero.
