但是将这种推力转化为一种拉力需要更加复杂的光学，比如，在格里尔的设计中，是通过一种螺线管状光束。

But turning this push into a pull required more sophisticated optics -in Grier's case, a solenoid beam.

如果分模面不能在单一平面，利用设计的对称性来减小侧向推力不失为一种好方法。

If the parting line cannot be on a single plane, then it is good practice to use symmetry of the design to minimize the side thrust forces.

MSH系列产品作为针对高压应用的设计，轴向推力通过平衡室系统和圆盘一起进行平衡。

The MSH range is designed for high pressure applications and the axial thrust is balanced by the combination of the drum and disc.
