小心坠落的岩石。
我尝试就在这儿拿一些光释光的样本，但是，当一些小的沉积开始在我周围坠落，我决定把一个金属馆子锤进岩石里当桩也许不是一个好点子。
I tried to get a sample for O.S.L. dating here, but when bits of the deposit started falling down around me, I decided that hammering a metal pipe into this rock pile might not be such a good idea.
因为该地区地情并不稳定，易于发生岩石坠落和山体滑坡。
The area is unstable and prone to rock falls and landslides.
研究表明，数值结果和实验结果比对良好，这种基于势流函数理论的数值模型能够有效模拟水中岩石坠落激发表面波的生成过程。
Comparisons show that the experimental and numerical results are in good agreement, and the numerical model can be used to simulate the wave generation due to the submarine rock falling.
落物保护结构是在有坠落物体(如树木、岩石等)时，对司机提供适当保护的安全结构。
Falling-object protective structure (FOPS) can block objects (such as trees, rocks) so that it supplies protection for the operator.
最严重的一次崖体坠落，发生在2013年到2014年那个暴雪肆虐的冬天，长达几英里的山崖岩石全部发生滑落，但这种小插曲绝不仅仅是极端天气导致的。
The worst cliff-fall in living memory occurred during a storm in the winter of 2013-2014 when several yards fell into the sea at once. But these episodes are by no means restricted to extreme weather.
MDAS还被用于模拟水槽中底部抬升、底部塌陷以及水中岩石坠落激发的表面波生成过程。
MDAS are also used to simulate the wave generations caused by the bottom elevations, the bottom collapses and the falling rocks in the wave tanks.
