n.游隙；气擦；偏差
It turned out that this method could assure bearing in optimal windage condition in concrete working condition, accordingly achieve the longest service life. 实践证明这种方法可以保证轴承在具体的工作条件下处于最佳的工作游隙状态，达到最长的使用寿命。
Through the comparison of the theoretic data and the measured data, the windage between the measured blade and the designed blade is judged to direct the manufacture of blades. 通过被测数据与理论数据的比较，判断被测叶片与设计叶片之间的偏差来指导加工。
