A complete theoretical analysis of the fluid and solid dynamics of the torsional quartz crystal viscometer is presented which for the first time, establishes a firm theoretical basis for two working equations whereby the viscosity of a fluid may be determined from measurements of the resonant frequency of the crystal and the width of the resonance when immersed in the fluid. Modern instrumentation means that it is possible to achieve higher resolution in the measurement of these two quantities than hitherto and the new theory opens the way to securing a concomitant accuracy in the determination of viscosity.

扭转石英晶体粘度计

对扭转石英晶体粘度计的流体和固体动力学进行了完整的理论分析,首次为两个工作方程建立了坚实的理论基础,从而可以通过测量谐振频率来确定流体的粘度。浸入流体中时的晶体和共振宽度。现代仪器意味着可以在这两个量的测量中获得比迄今为止更高的分辨率,而新理论为确保粘度测定的伴随准确性开辟了道路。
