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。

Thus the clearance on the fastening sealing part of the groove part on the shell side and the foot part in the outer lens side is not generated.
因此能够避免壳体侧的沟部与外透镜侧的脚部卡合的密封部上产生间隙。

This paper introduces a technique for the elimination of clearance between the explosive charge and the bottom of shell, besides a testing method adopted for the process is given.
