中文摘要:
      本文研究了硫酸水溶液的超声波特性。用脉冲回波法在0~75℃温度范围测量了不同浓度硫酸的声速,并计算得诸如摩尔声速、声阻抗、绝热压缩系数、分子间自由程以及纯H2SO4液体的声速等参数,另外还推算出逾量声速、逾量绝热系数、逾量分子间自由程。
英文摘要:
      In this paper, an ultrasonic study has been made of the state of sulphuric acid in water. Ultrasonic velocity of sulphuric acid in water as a function of concentration has been measured using pulse-echo method in the temperature range 0~75℃ and various parameters such as molar sound velocity, specific acoustic impedance, adiabatic compressibility, intermolecular free length for the solution and the ultrasonic velocity of pure sulphuric acid have been computed from the measurement results. Excess ultrasonic velocity, excess adiabatic compressibility and excess intermolecular free length have also been calculated.
