| 摘 要： | 在航空发动机试车及传动润滑系统试验时，需要经常对油气腔进行量级极小的压力测量，其测量介质是油气混合物，经常发生测不准的情况。为此，根据流体力学的观点，对上述问题进行了分析探讨，并提出了解决方法。

| Abstract: | The measurement of minimal level pressure for the oil-air chamber （the measurement medium was the oil-air mixture） is performed frequently during the aeroengine rig test and the driving lubrication system experiment, and the measurement results are often inaccurate. Therefore, based on the fluid mechanics, the problem is analyzed and the solution is also presented. |
