This feature gives a reasonable explanation for the mechanism of CAS. The phase velocity of diffraction fields for uniform plane wave on a circular aperture has been investigated. It is shown that diffraction can result in subluminous phase velocity at certain points of optical field in vacuum.

如果相对论电子能够注入到这一通道内，那么它与激光场间的相移就可能变得非常小，从而能够长时间地保持在加速相中得到极高能量。

There's a circularity to it that confused me for a long time.

We put up with it for a long time till Fly Molo finally gave up and when one of the teachers was quoting one of Von Clausewitz's stupider generalizations, Fly continued the quotation, sentence after sentence, paragraph after paragraph, and the rest of us joined in as best we could -- I mean, nobody has a memory like Fly, but we do OK -- and they finally got the idea that we could teach the stupid classes to them.

我们忍受了那么长时间直到弗莱·莫罗最终放弃，而有一个教师提供了一份冯·克劳斯维兹的愚蠢的计划。弗莱沿用了这个计划，一句句，一段段，保持我们最良好的加入。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
