| 摘 要： | 液体的粘度和表面张力系数是表明液体性质的两个重要参数，人们常常用不同的仪器和方法去测量。在教学中发现，奥氏粘度计不仅可以测量液体的粘度，而且可以测量液体的表面张力系数，同样采用比较法，其测量的精度比用拉脱法的高、省事．所用样品量少、易掌握。这样用一种仪器测量同一个样品的两个物理量，对于研究液体的性质是方便的．

| Abstract: | Viscosity coefficient and coefficient of the tensien are two important parameters.Many researcheres have used different instruments and methods to measure both of them. In this paper,it is shown tbat Ostwald's viscometer can meausre boh of them. Experiment proves that akindaof measure ment are accurate,times and samples are saved,and it is easy to master. |
