1.This machine is either a backscatter X-ray or millimeter wave scanner.

这类机器是反向散射或是毫米段波。

2.If the machine just looks like a flat wall, it's probably a backscatter X-ray scanner.

如果这个机器看起来像一堵墙，它可能就是反向散射。

3.She has yet to analyse the data fully, but preliminary investigation indicates that both snow depth and temperature influence backscatter.

她还没有充分分析数据，但初步调查表明，雪的深度和温度会影响后向散射。

4.They're the cylindrical machines that look like futuristic phone booths, and they use the same basic principles as backscatter scanners.

它们呈圆柱形状，看起来像电话亭，它们的工作原理和反向散射一样。

5.So when you shoot lasers through the fibers, those impurities backscatter some of the light right back to the laser source.

因此当你通过送激时，这些杂质会将一部分反射回激源。

6.Buried fibre-optic networks can detect underground vibrations by the " backscatter" they cause in the photons travelling through the cables.

埋地网络可以通过地下振动在穿过电缆的子中引起的“反向散射”来检测地下振动。机翻

7.As they towed it, they sent radar pulses on the frequency bands used by the satellites downwards into the snow and measured the amount of backscatter.

当他们拖着雪橇的时候，他们在卫星使用的频段向雪中射雷达脉冲，并测量反向散射的数量。

8.The deflection of the signals in this backscatter gives a picture of how particular snow conditions might be changing the way the satellite's radar is returned.

散射中信号的偏差说明了特定的雪况可能会如何改变卫星雷达返回的方式。

9.The amount of X-ray radiation you're exposed to in a backscatter scan is extremely low, a tiny fraction of the amount you're about to be exposed to by flying on a plane.

反向散射器辐射非常小，比在飞机上接受的辐射少得多。
