摘要
为准确、有效地区分引起石英晶体微天平(QCM)频偏的质量效应与阻尼效应,运用能量传输模型(ETM)的基本原理,推导出液体粘度和密度的乘积与石英晶体谐振器表面最大的振动幅度之间的显性函数关系式。可通过测试QCM的谐振频率与幅值信息将其负载效应分开,为QCM免疫传感器在医学中的诊断提供了一种理论基础。
In order to accurately and effectively distinguish the effects of mass loading and damping loading of a quartz resonator vibrating in damping environment, the energy transfer model（ETM） was introduced to deduce functional relationship between the product of absolute viscosity and density of the liquid deposit and the maximum amplitude of vibration at the quartz-resonator surface. Then the effect of mass loading could be rapidly distinguished from damping loading by measuring the frequency shift and the amplitude of QCM simultaneously. This method pro- vided a new theoretical basis for the application of QCM immunosensor in medical diagnosis.
