Therefore, remember to change oil in the oil pan and air compressor into winter-use oil when winter comes; change gear oil in the transmission, transfer case, differentials and steering gear into winter-use oil, after cleaning the hub bearing; add bearing lubricants of low viscosity; change into winter-use oil with low solidifying point, for diesel engines in the severe cold area.

因此记住当冬天来临时要把承油盘和空气压缩机里的油换成冬天用油；在清洁完轮毂螺栓后，把在传送装置、变速箱、差动齿轮和操纵装置中的齿轮油换成冬天用油；加入低粘度的轴承润滑剂；对于处于非常寒冷的地区的柴油发动机，冬季用油要有较低的凝点。

Comparing the unsteady flow fields obtained by CFD with the measurement results with SPIV, it can be found that the CFD results can capture the main characteristics of the flow fields observed in the experiment results, however, the precision of the CFD needs to be further improved, and to predict the detail flow structures, such as the tip leakage vortex in the compressor rotor, by CFD still has some difficulties, thus, some work should be done to improve the turbulence model for more accuracy prediction of the flow fields by CFD for the complex flow in turbomachinery.

定常计算结果和非定常计算结果都不能很好地反映出转子叶尖泄漏流，转子尾迹和泄漏流在静子通道中的演化，及其与静子的相互作用等复杂流动情况。开展叶轮机适用的湍流模型研究，对于提高叶轮机内部复杂流动数值模拟的准确性具有非常重要的价值。

SPIV was applied to a large-scale low-speed compressor facility with the configuration of the two CCD cameras placed on either side of the light sheet to make the measurement of the complex flow in hub-to-tip cross sections possible and to avoid the disturbance from the light sheet probe as used in the periscope-type configuration, which can also be easily used in multistage and high-speed turbomachinery.

本文将数字式SPIV技术应用到低速大尺寸压气机实验台上，解决了压气机内部非定常复杂流动瞬态场的技术难题，所发展的SPIV测量技术同样适用于多级叶轮机械；并在设计状态和近失速状态下，对转子槽道内叶尖区域及转静干扰条件下静子槽道内叶尖区域多个截面内的三维瞬态速度场进行了成功测量。
