1990年，日本发射了一个小型探测器，完成一次靠近月球的短暂飞行。

In 1990, Japan launched a small probe completing a brief fly-by the moon.

因此很多这类微型通信设备可能仅需一节小型的五号电池（AA型，电压1.5伏）就可以工作，而传统的雪崩光电探测器需要20-30伏的电量供应。

Thus many of these tiny communication devices could potentially be powered by just a small AA-size battery, while traditional avalanche photodetectors require 20-30V power supplies.

由于SpectraFluidics公司的爆炸物探测器基于纳米技术，因此体积较小，能够装载在小型手持探测器中使用。

Since the SpectraFluidics explosives detector is based on nanotechnology, it is naturally small and can be engineered to operate within a small handheld detector.
