【摘要】 本文首先应用化学热力学方法推导出弛豫吸收公式和唯象理论的假定;其次借助于Debye-Hckel离子云理论,将所得结果应用MgSO₄水溶液中去,并对以往发表的有关工作进行了讨论;最终指出,MgSO₄水溶液的弛豫吸收机构用 MgSO₄Mg⁺⁺+SO型的反应来说明是不够恰当的。更多还原

【Abstract】 The assumption of the relaxation of the reaction MgSO4(?) Mg+++SO4-- to be the basis of sound absorption in water has not sufficient ground. In this paper, the author derives a formula for relaxation absorption based on the chemical thermodynamics, and the supposition from which the phenomenological theory started is also explained. With the consideration of Debye-Hükel ionic atmosphere theory, the formula obtained is applied to the water solution of MgSO4. A critical discussion is given to the existing theories.更多还原
