摘　　要：以电动吸痰机作为润滑油吸入器和清洗器,利用SYP1003型运动粘度测量器测定了4010和4106航空润滑油在不同温度时的运动粘度,并确定了它们在Walther-ASTM模型下的粘温表达式。结果表明:粘度较低或油的温度较高时,润滑油显示出较好的粘温特性;4010润滑油的粘温性能好于4106润滑油。在0-100℃温度范围内,可用Walther模型预测上述两种油的粘温关系。The kinematical viscosities of aviation lubricating oils No.4010 and 4106 in several temperatures were investigated with SPY1003 viscosity instrument and electric sputum collector. The visco-temperature expressions of these two oils based on Walther models were determined. The results show that 4010 has better visco-temperature performance than 4106 and the lubricating oil has better visco-temperature performance at higher temperature or lower viscosity. The viscosities of these two oils within the temperature range of 0 - 100℃ can be obtained with the Walther models.
