One part is a targeted search using the world's largest radio telescopes, the American-operated telescope in Arecibo, Puerto Rico and the French telescope in Nancy in France.
"其中一部分是有针对性的搜索，使用了世界上最大的射电望远镜，分别是：在波多黎各阿雷西博的由美国操作的望远镜，在法国南茜使用的望远镜。
Puerto Rico's Arecibo Observatory is only 300 meters in diameter.
波多黎各的阿雷西博天文台望远镜直径仅300米。
However, in practice, we find the signal provided by Arecibo isn't 100% correct.
然而在实践中，我们发现阿雷西博说提供的信号并不是100%正确的。
The signal collecting area of each system would be at least100times greater than that of the arecibo telescope.
每个系统的收集信号的区域至少一百倍于阿雷西博望远镜。

每个系统的收集信号的区域至少一百倍于阿雷西博望远镜。
A sphere, in contrast, concentrates its beam to a line - which is why a "line feed" antenna was originally used at Arecibo.
球形的则不同，它会把波束汇聚到一条线上——这就是为什么阿雷西博先前使用的是“线反馈”天线。
This means that the SETI receiver was perched permanently above the Arecibo dish at the base of the aging line feed antenna.
也就是说SETI的接收器永久的占据着阿雷西博碟型天线上老化的线性馈源的底部。
Over time, even without being granted dedicated telescope time, the piggy back SETI receiver managed to scan the entire sky visible from Arecibo.
随时间流逝，即使没有获得专门的望远镜时间，附加式的SETI接收器也能扫描完整个天空。
The Gregorian dome, due to its unique geometrical shape, focuses the signal reflected by Arecibo spherical dish one a single point inside the dome.
“罗马穹顶”由于它独特的几何外形，将阿雷西博球形碟面反射来的信号聚焦到它内部的一个点上。

He wants to use the world's largest radio-telescope dish, at Arecibo in Puerto Rico, as a transmitter to beam some kind of radio greeting towards nearby stars.
他想要使用位于波多黎各的阿雷西博，世界上最大的无线电天文望远镜天线，作为发射器向邻近的恒星发射各种无线电问候。
Because it is so hard to acquire sufficient telescope time for a sky survey, SETI observations at Arecibo were conducted up to now in the in the piggy-back mode.
因为很难得到充足的望远镜使用时间进行全天调查，如今SETI在阿雷西博的观测采取的是一种附加式的模式。
New data from the arecibo radio telescope in puerto rico seem to hint that this is the case but only the cassini orbiter and the huygens probe can provide confirmation.
由波多黎各的阿雷西波望远镜获得的新资料似乎暗示这个情形，但是只有卡西尼号轨道船和惠更斯号探测器能加以确认。
You will be amazed by the greatness and beauty of the nature captured by talanted photographer Carlos Gotay from Arecibo, Puerto Rico, and will try to find right epithets to describe your feelings.
这些来自波多黎各阿雷西博市的天才摄影师卡洛斯戈泰的作品，让你惊讶于自然界的宏伟与美丽，并一直在脑海里搜索合适的词语来形容你的感受。
This is significant because of the unique geometrical features of the Arecibo telescope: whereas most radio dishes are parabolic in shape, the Arecibo dish is a giant half-sphere dug into the ground.
这非常重要，由于阿雷西博望远镜的独特几何结构：尽管绝大多数的射电望远碟面都是抛物面型的，而阿雷西博的碟面是在地上挖出的一个巨大半球。
