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。

They point to the Sakhalin-2 project off Russia's Far East coast, where Gazprom gained majority control from Royal Dutch Shell last year, after Russian authorities refused to give Shell environmental clearance for the scheme.
