By using nonoverlapping domain method,a 3-D viscous code had been developed to calculate flow field in a cascade with tip clearance and craping along casing. 本文给出了一种基于区域分解算法的可考虑动叶顶部间隙和机匣刮削作用的涡轮级计算方法。
Special multicrown designed gearing with limited radial clearance perfectly centring the rotating pieces and eliminating lateral vibrations. 专门采用多齿轮冠设计的齿轮装置，其限定的径向间隙能够完美地实现与旋转部件的对中，消除了横向扰动。
The radial clearance can be adjusted on certain versions, which means the user can achieve clearance-free or preloaded guidance systems. 该径向间隙可以调整的某些版本，这意味着使用者可以达到清除免费或预装的导航系统。
