常速英语:酒商使用低科技生物传感器检测水质

It is an old standard in the brewing industry the good beer starts with clean fresh water,so there’s all kinds of high-tech ways to monitor water quality throughout the brewing process.But this is a decidedly low-tech way to test for clean water.
这是酿酒行业的一个古老标准，好的啤酒从干净的水开始，所以在整个酿造过程中都有各种高科技的方法来检测水质，但这种测量洁净水的方法无疑是一种低技术含量的测试法。

“We have five crawfish controlling the water quality here, they’re connected to a computer and we are following their pulse activity and movement.When three or more crawfish move or change their pulse activity.We know that the water parameters have changed.We’re able to react quickly because we have the result within three minutes. ”
我们有五条小龙虾控制着这里的水质，它们与电脑相连，我们会关注它们的脉冲活动和运动。当三个及三个以上的小龙虾发生变动或脉冲活动时，我们就知道水的参数发生了变化，我们能够迅速作出反应，因为三分钟之内就能有结果。

But why crayfish? The Czech scientists who come up with the idea say, crayfish are really sensitive to all kinds of changes in their water.
但为什么是小龙虾？提出该想法的捷克科学家说，小龙虾对水中的各种变化非常敏感。

“Crayfish reacted very quickly to any nonspecific change, which is different to any other detectors, which react to a very low concentration of pollution but only to one specific agents.”
小龙虾对任何非特异性变化的反应都非常快，这与其他任何检测器都不同，虽然后者对浓度很低的污染有反应但是只对某一种特定的药剂产生影响。

The scientists say they are expanding their crayfish biosensor program into other areas where clean water course.
科学家们说，他们正在把小龙虾生物传感器项目扩展到其他清洁水源的领域。
