1 ?距离差 与TDOA类似的一种方法是计算不同传感器与目标之间的距离差（range difference，RD），它等于信号在传播媒质中的传播速度与TDOA的乘积。一般认为空气中电波的传播速度为光速。

The difference between today's workplace and the "dress for success" era is that the range of options is so much broader. 如今的职场与“为成功而着装”时代的区别在于，选择的范围要广泛得多。 - 2
Those creatures have long had four-color vision, but a key difference is that their fourth type of color detector is in the high-frequency ultraviolet range, beyond where humans can see. 这些动物早已拥有四色觉，但关键的区别是，他们的第四种颜色位于高频的紫外线区域，在人类可视范围之外。 - 3
We can think about the Lyman series, which is 1 where n equals 1. We know that that's going to be a higher energy difference, so that means that we're going to be in the UV range. 我们可以来看看Lyman系,也就是n等于,我们知道它的能量差更大,所以它在紫外光区内。
