本文测量了具有羧酸官能团的自组装硫醇单层包覆石英晶体微天平（QCM）在水溶液pH值变化时的谐振频率。随着pH活度的增加，拉伸应力的增加部分促成了QCM的响应，但主要的贡献是由于与QCM接触的水动力层的粘弹性特性的变化。参28。， 3个无花果。
The resonant frequency of the quartz crystal microbalance (QCM) coated with self-assembled thiol monolayers with carboxylic acid functionality is measured while the pH of the aqueous solvent is changed in this paper. Increased tensile stress with increasing pH activity partially contributed to the QCM response, but the major contribution was due to changes in the viscoelastic properties of the hydrodynamic layer in contact with the QCM. 28 refs., 3 figs.
