由于液压挺杆自动调节气门间隙为零间隙，同时可降低发动机噪声。

Because the hydraulic valve plunger automatic control valve clearance is zero gap, simultaneously may reduce the engine noise.

因此，实现了零间隙，即，在微透镜之间不存在 间隙，微透镜的填充系数被最大化。

Thus, a zero gap is realized, where no gap between micro lenses exists, and the fill factor of micro lens is maximized.

轴承表中给定的速度评级值适用于单一的安装，轻轻预装nke的主轴轴承(即零间隙操作)。

The values of speed ratings given in the bearing tables apply to single mounted, lightly preloaded NKE spindle bearings (ie operating at zero clearance).
