    • This invention relates to a method for deciding an amount of correction factor for the viscosity of a fluid test sample needed for correcting a calculation or measurement of the density based on the viscosity. The method for deciding the viscosity of the fluid test sample, during a density measurement performed by an oscillating densitometer where there is a peak point on the viscosity-attenuation constant characteristic of the test sample at the specific order oscillation, is to decide whether the attenuation constant of the viscosity-attenuation constant characteristic of the test sample at the other specific order oscillation is larger or smaller than that corresponding to the peak point, to decide according to said decision whether the viscosity detected by the attenuation constant obtained at the specific order oscillation belongs to either side larger or smaller than the peak point, and then to decide upon and determine the viscosity of the test sample according to the above two decisions.
    • 本发明涉及一种用于基于粘度来确定校正密度的计算或测量所需的流体测试样品的粘度的校正因子的量的方法。用于确定流体测试样品的粘度的方法 通过振荡密度计进行的密度测量,其中在特定次序振荡下测试样品的粘度 - 衰减常数特征具有峰值点,是确定测试样品的粘度 - 衰减常数特性的衰减常数 其他特定顺序振荡大于或小于对应于峰值点的振荡,根据所述判定来确定由特定阶振荡获得的衰减常数所检测的粘度是否属于峰值点以上的任何一侧,然后 根据上述两个d来决定和确定测试样品的粘度 决定。
