The first is distributed data processing , such as physical simulations , radio signal analysis , genetic analysis , computer graphics rendering and financial modeling 第一类是分散式资料处理，像是物理模拟、无线电讯号分析、遗传分析、电脑绘图计算，以及金融模型。
Another branch of astrobiology , through a programme called seti search for extra terrestrial intelligence is concerned with trying to locate radio signals emitted by alien civilizations 天体生物学的另一究科目，是透过寻找地外智慧生命计划seti试图接收外星文明发出的无线电讯号。
As the intensity of radio - frequency interference in our environment grows , we have to raise the volume of radio signals so that they can be heard over the electromagnetic background noise 由于环境中的无线电波干扰日渐增强，因此我们必须提高无线电讯号的强度，才能从背景的电磁杂讯中分辨出讯息。
Instead of wastefully broadcasting personal communications ? such as cell - phone calls ? in all directions , these innovative antennas track the positions of mobile users and deliver radio signals directly to them 这种新型天线会追踪行动用户的位置，把无线电讯号直接发射给他们，而不会浪费地朝著四面八方播送个人通讯（比如行动电话） 。
Throughout the descent , shifts in the frequency of the probe ' s radio signal will be monitored to infer the strength of titan ' s winds , and the huygens atmospheric structure instrument ( hasi ) will measure temperature , pressure and electrical fields that could indicate the presence of lightning 下降过程中将持续监测探测器无线电讯号的频移，以推算土卫六风场强度；而惠更斯大气结构仪（ hasi ）会量测温度、气压以及可能显示闪电是否存在的电场。
