火山

Suggested causes of ice age periods include the positions of the continents, variations in the Earth's orbit, changes in the solar output, and vulcanism.

导致冰河期形成的可能原因包括：大陆的位置，地球轨迹的变化，太阳辐射的输出，以及火山的作用。

Another possibility is vulcanism: Although there is no evidence of currently active Martian volcanoes, ancient methane trapped in ice "cages" called clathrates might now be released.

另一种可能性是vulcanism ：虽然目前没有证据表明火星上的火山活动，古甲烷被困在冰"笼子"称为clathrates现在可能被释放。

Praxis apparently played host to the largest of these, and Lang, to name one, has speculated that the Pits not only gave rise to extinct creatures, but succeeded in regressing the entire planet to a formative stage of destructive vulcanism.

普拉西斯上的起源坑，显然是它们中最大的一个。朗等人推测起源坑不仅仅能复活已灭绝的生物，而且能使整个行星回退到火山活动频繁的成型时期。

In this ***, T_2 cutoff value of glutenite cores mostly distributed between 10 and 30 ms, carbonatite cores were about 100ms. T_2 cutoff values of vulcanite cores changed great with lithology, and average T_2 cutoff value of rhyolite cores was 87.91 ms, tuff was 52.02 ms, and volcanic breccia was 36.28 ms.

在本文所测岩心中，砂砾岩岩心T_2截止值大多集中在几ms～30ms之间，碳酸岩岩心T_2截止值均在100ms左右，火山岩岩心T_2截止值随岩心岩性变化较大，大庆油田岩心中流纹岩均匀值为87.91ms，凝灰岩均匀值为52.02ms，火山角砾岩均匀值为36.28ms。

The site continues to enrich the field of vulcanology .

群岛仍然继续丰富火山学领域的研究。

I have never seen a waterfall like that before .

我还从来没见过火山。

Or, you can send burning flows of lava from a well-placed volcano.

或者，也可以从一个位置不错的火山那里释放出燃烧着的熔岩之流。

Wilberforce: I was just reading about supervolcanoes. It's a very interesting subject.

威伯福斯：我正在读超级火山的文章，这是一个很有趣的主题。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
