光纤技术为滑坡监测开辟新领域

Aaron Sidder, freelance science writer by Aaron Sidder 30 August 202230 August 2022

为了研究中国三峡水库沿线的一处滑坡,研究人员在现场布设了光纤传感器,来监测地下温度、湿度和应变。

A copper mine delves deep into the orange rock of an Arizona desert. More than a dozen even steps have been excavated leading down to a roughly circular depression in the ground. Some of the steps have patches of oxidized copper, a blue-green color. A smooth path large enough for heavy machinery spirals down into the bottom of the mine.
