The results of experiment show that the servo method can meet the requirement of non circular cutting system for high frequency, high accuracy and robustness performances.

实验结果表明：该方法能够满足非圆数控车削系统高频响、高精度和强鲁棒性的要求。

During summer on the top half of Earth, our planet is actually farther from the sun than during winter, a fact owing to our non-circular orbit around the sun.

在地球的上半部分为夏季的时候，实际上这时的地球离开太阳的距离比在冬季还要远。所以会这样，是由于我们围绕太阳运行的轨道，并不是圆的。

With the linear motor as the micro-feed servo mechanism, the numerical control machine can solve non-circular machining problem.

数控机床采用直线电机作为刀具的伺服进给机构，可以解决非圆零件的加工问题。

It would have 80 independently rotating, non-circular floors.

ECONOMIST: Monitor

But again, if you accept the circular logic of appeasement - that always puts the burden of proof on the non-aggressor - then you will never learn these, or any other lessons.

The chamber was packed, with the MEPs - including Robert Kilroy-Silk making a very rare appearance, sitting in the non-aligned section with Jean Marie le Pen et al - parked behind their computer screens in semi-circular rows.
