在这个原理被发现之前，工程师们已经制造了利用这个原理的仪器，例如测量船下的海洋深度。

Before this was discovered, engineers had already built instruments to exploit the principle, for example to measure the depth of the sea under a ship.

成本的降低使得研究人员、业余爱好者甚至小学生能够将简单的仪器放入近地轨道，甚至可以由国际空间站对它们进行部署。

This decrease in cost allows researchers, hobbyists and even elementary school groups to put simple instruments into LEO or even having them deployed from the ISS.

他们的仪器探测到了频率为3千赫的非常微弱的无线电波。

Their instruments detected very faint radio waves at a frequency of 3 kilohertz.

So, our detection devices are a little bit limited here today, we're actually only going to be using our eyes, so that means that we need to stick with the visible range of the electromagnetic spectrum.

我们今天所有的探测仪器十分有限，实际上我们要用我们的眼睛来观测，这意味着我们只能看到,电磁谱中的可见光区间。

So basically, what he wants us to do is redesign this and produce something better and then possibly patent that.

所以，医生希望我们能重新设计这种仪器，发明出更加先进的仪器，有可能的话，还可以申请专利。

I don't think it very relevant whether the death comes about because you withdraw life support, like a ventilator, or because you actually decide to end that child's life by giving the child a lethal injection.

我觉得这也与造成死亡的原因无关,无论是通过撤走维持生命的仪器，比如呼吸机，还是通过药物注射,结束孩子的生命。
