While directly measuring the cycle time of the tyre and shell, the dynamic clearance be-tween the tyre and shell can be carried out by some calculations.
其原理是通过直接测定轮带和筒体的回转周期，来自动计算轮带与筒体之间的动态间隙。
I have made a cycle check on No. 1 auxiliary engine and a general check on the clearance between the intake and exhaust valves.
我已对一号辅机作了循回检查，并对进排气阀的间隙进行了惯例检查。
