本文叙述一种特别适于在很宽的温度和饱和液体蒸汽压范围内进行测量的毛细管粘度计。饱和液体可能是腐蚀性的,不能与合成橡胶接触,或者得到的数量少至1ml。粘度计的准确度大约是3%。利用最近发展起来的致冷剂(其中某些目前还不能大量得到)对仪器进行了测试。图1(略)和图2表明粘度计的构造。该 This article describes a capillary viscometer that is particularly suitable for measurements over a wide range of temperatures and in the vapor pressure of saturated liquids. Saturating liquids may be corrosive, do not come into contact with the elastomers, or be as little as 1 ml. Viscometer accuracy is about 3%. The instruments were tested with recently developed refrigerants, some of which are not currently available in large quantities. Figure 1 (omitted) and Figure 2 shows the viscometer structure. This
