干涉计

These are clearest when the length of the two arms of the interferometer are equal.

当干涉计的两个臂长是相等的时候产生的干涉条纹最清楚。

What distances then are to be measured by our interferometer?

距离然后要被我们的干涉计测量什么？

Of these, the Michelson interferometer has been most important in the past and is still of some significance.

像这里，迈克尔逊干涉计就着非常重要而且至今也非常重要的仪器。

The Keck Interferometer will combine the light of the world's largest optical telescopes, extending our vision to new distances.

Keck干涉计将联合世界上最大的光学天文望远镜，以此扩充我们的视野到新的未知领域。

By the use of a Michelson Interferometer, most light sources can be made to produce interference fringes.

通过使用迈克逊干涉计，大多数的光源能够产生干涉条纹。

To help answer this question, Carilli, Riechers and the rest of their team used the Very Large Array radio telescope in New Mexico and the Plateau de Bure Interferometer in France to peer back to near the beginning of the universe, thought to be 13.7 billion years ago, when the first galaxies were forming.

为了回答这个迷，Carilli， Riechers 和他们的小组成员在新墨西哥州用非常大的阵列无线电望远镜和在法国用高原日布雷干涉计去探索宇宙的起源是在137亿年以前，也是第一个星系形成的时间。

Description: An interferometer, as suggested by its name, is a device that uses interference between two beams of collimated light to make measurements.

描述： 一个干涉计，如它的名字所，是在二照准光的光线之间的一个使用冲突的装置制造测量。

For this experiment, one of the mirrors constituting one of the two arms of the interferometer is attached to a micrometer translation stage.

对于这实验，构成干涉计的二双臂之一的镜子之一被附上到一个测微计翻译阶段。

The restriction to 100's of nanometers is not due to just the properties of interferometers but to the precision of the translation stages used to make the very small distance changes.

对 100 年代的奈米限制由于只是干涉计的财产是不但是对翻译阶段的精密过去一直作非常小的距离变化。

Scientists can then figure out which signals are from local disturbances and which are from gravitational waves by comparing data from interferometers in different parts of the world.

科学家们还将比较分布在世界各地的干涉计的检测结果，以判别信号是真地来自引力波还是来自于本地的干扰。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
