This causes an adiabatic compression in the front of the expansion and a large density difference is formed there. The difference with adiabatic energy is transported as an acoustic wave. This rapid heat transportation is called \u0027Piston Effect\u0027. In our study, an ultra-sensitive and high-speed density measurement system was developed to conduct a quantitative measurement of the \u0027Piston Effect\u0027. By using the system, we succeeded to directly observe the elementary process of \u0027Piston Effect\u0027. To demonstrate the performance of the system, the measurement of sound velocity in a critical fluid was conducted. Using the FFT method to the experimental results, the sound velocity could be precisely evaluated. The velocity profile versus temperature from the experimental results shows a good agreement with the simulation results and theoretical prediction, that is, the profile should have the scale universality. However, the profile from the experimental results obeys another scale universality if T-T(sub c) is less than 0.1 K. These indicate that our experimental system enables us to quantitatively discuss the critical phenomena.", "subitem_description_type": "Other"}]}, "item_3_description_32": {"attribute_name": "資料番号",
