1、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。
2、Most antennas are made in the shape of a dish to collect and reflect the radio waves to the sub reflector, in the same way as a curved mirror focuses visible light to one point.───大多数天线被制成碟形，用以收集和反射无线电波至亚反射器，就像曲面镜将可见光聚焦于一点一样。
