Arranging opening time, back beam height, tension, opening Angle, drafting, reed-in reasonably were adopted in weaving process. These practice ensures no loop and enhance weaving efficiency.

织造工序要合理设置开口时间、后梁高度、上机张力、开口角度，并合理安排穿综及穿筘工艺，保证了经纱不起圈，且织造效率提高。

Then you send laser light through a beam splitter to divide the beam between the two arms, and let the light bounce back and forth a few times before returning to the beam splitter.

然后你通过分光器发射一束激光，让光线在两条边不断反射再回到分光器。

If the two arms have identical lengths, then interference between the light beams returning to the beam splitter will direct all of the light back toward the laser.

如果两条边一样长，分光器发射的激光将被完全反射回分光器。

And then I could put a couple of plates and I could raster the beam so that when I am looking here,the beam goes back and forth about 80 times a second.

然后我放了两个感光片,我可以检测到光束所以,当我观察时,电子束以每秒80次的速度来来回回了。

Controllers are still activating Curiosity's instrument package, and all antennas that will beam back data to JPL "work perfectly, " mission manager Jennifer Trosper said Wednesday.

One thing we can confirm, though, is that it has a camera on board to beam back images and (per the picture to the right) Seiko Epson has all kinds of sci-fi delusions in mind for its future uses.

From a standing start, the reconstructed beam sped back up to the normal speed of light.
