摘要
本文通过对奥氏粘度计测量公式的推导 ,阐明了粘度计中毛细管两端口的压强差△P随时间的变化关系 。
This paper makes a detailed calculation and analysis of viscosity coefficient in Ostwald viscosimeter,and demonstrates the change of pressure difference(△P) at the two openings of the capillary along with the change of time(t),and further derives the regular measure equation from this relation.
