尾轴

In this way, the formation of a groove it ABCDEA "i" shape of the seal space (such as single-head screw, the axial groove to Shun Rao screw plate to the mouth through the smoke emission and can not form a seal).

那样，凹槽ABCDEA也便组败一个&i&形的密封空间(如采取双尾螺纹，则凹槽将逆轴向盘饶螺杆，将吸排口贯通，无奈构成稀封)。

C. The quality problem of head annulus and tail wheel itself, make their coaxial is spent and demand of radial round jumpy precision is insufficient.

头轮和尾轮本身的质量新问题，使得他们的同轴度和径向圆跳动精度要求不够。d。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
