摘要
用ＮＹ１型高压毛细管式粘度计和恩氏粘度计，实测了ＳＲ２８高精度陀螺马达润滑油的压粘关系和粘温关系；测出了该油的介电常数随温度的变化规律；求出了压粘关系、粘温关系及介电常数随温度变化关系的拟合公式。拟合结果与实测结果的相对误差小于５％
The pressureviscosity and viscositytemperature relationships of SR28 high precision top motor lubricating oil were measured by using model NY1 high pressure caplastometer and Engler viscometer respectively. The dielectric constant of the oil was measured. Empirical formulas of pressureviscosity, viscositytemperature and dielectrie constanttemperature relationships of the oil were obtained respectively.
