In effect, the Gregorian dome transforms Arecibo's spherical dish into the equivalent of a parabolic dish.
效果上“罗马穹顶”将阿雷西博的球形碟面变成了抛物面形碟面。
Parabolic dish concentrators are similar to trough concentrators, but focus the sunlight on a single point.

To increase the solar pump power, the structure of multi-mode fiber array or parabolic dish concentrator array combination with tapered fiber bundles is put forward.
为了提高太阳能泵浦功率，提出通过光纤集束熔锥侧面耦合器构成多模光纤阵列或者聚光器阵列的结构。
When using a line feed, telescope operators produce a unified signal by adding up the different parts of the signal, but the results are never as strong and clear as they are with a parabolic dish.
使用线形馈源时，操作者产生一个标准信号叠加到信号的不同部分，但是结果从不会像使用抛物面碟面得到的那样强大、清晰。
In addition to parabolic troughs and power-towers there is also a third solar-thermal technology, which combines curved, dish-shaped mirrors with heat engines.
