1、Parabolic dishes have the advantage that they point their beams to a single point at their focus, creating a clear and strong signal.───抛物面碟面的优点是能将波束在它的焦点处汇聚到一个单一的点，产生一个清晰、强力的信号。
2、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，Cao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。
3、move to the right of the parabolic trend line is an exit signal.───运行到抛物线形的趋势线右边是该趋势结束的信号。
