导出了新的单位波长超额声吸收和弛豫频率的计算公式。这些方程是在假设（AB）（A）+（B）类型的解离过程因假设的平衡压力依赖性而受到声场不可逆扰动的假设下推导出来的。将这些方程应用于稀硫酸镁溶液中的过量声吸收问题，通过使用二氧六环和水的混合物来改变溶剂的介电常数，实验研究了改变溶液中离子库仑相互作用力的影响。定量地解释了这项工作和其他研究者对稀硫酸镁溶液中过量声吸收的研究，并测定了硫酸镁在水和水-二氧六环溶液中的离解比速率和离子缔合比速率。良好的协议之间的质量作用平衡常数的值确定的声学手段和值d…
New equations for the excess sound absorption per wavelength and the relaxation frequency have been derived. These equations are derived on the assumption that a dissociation process of the type (AB)⇌(A)+(B) is irreversibly perturbed by the sound field due to assumed pressure dependence of the equilibrium. These equations are applied to the problem of excess sound absorption in dilute magnesium sulfate solutions.By using mixtures of dioxane and water to vary the dielectric constant of the solvent the effect of varying the ion Coulombic interaction forces of the ions in solution has been studied experimentally. This work and the work of other investigators on the excess sound absorption in dilute magnesium sulfate solutions is explained quantitatively.The specific rates of dissociation and ion association for magnesium sulfate in solutions of water and water‐dioxane have been determined. Good agreement is found between values of the mass action equilibrium constant determined by acoustic means and values d...
