Streams of lava light up Mount Etna during a two-hour eruption on Tuesday night-the peak of the Italianvolcano's fiery week (Mount Etna map).
星期二晚,埃特纳火山两小时喷发中,流淌的岩浆照亮了这意大利火山的山峰。
This, in turn, will lower the depth and turbidity of water in mountain streams, increasing the amount of damaging ultraviolet light that reaches the stream beds.
这反过来又会降低山区溪流的深度和浑浊度,增加紫外线到达河床造成的损害。
To investigate this effect, Clements and his team placed screens over small segments of a dozen mountain streams to block ultraviolet light, and left them there for 60 days.
为了调查由此产生的影响,克莱门茨和其研究小组选取了十几条山间溪流,将遮盖板放置在溪流的某一段以阻挡紫外线对溪床的照射。
