The average greatest grain-sizes of lithic fragments and pumice fragments in pyroclastic flow deposits decrease with increasing distance from the crater, indicating that gravity sorting and mechanical wearing did occur during the transportation of the pyroclastic flow.

火山碎屑流堆积中的岩屑和浮岩的平均最大粒度随着离开火山口距离的加大而减小，反映火山碎屑流搬运过程中存在重力分选和机械磨损作用。

Silicalites, predominated by pelitic silicalite, occur in collisional zones and back-arc basins. In the collisional zones, they occur as rock sheet as an important part ofophiolitic mé lange, belonging to ophiolitic mélange type silicalite. In the back-arc or interarc basin, they occur as pelitic silicalite intercalation varying in thickness, characteristic of "silica merl",and belonging to abyssal back-arc basin type or carbonate type silicalite. In the magmatic arc, they occur as intercalation related to volcanic hydrotherm or volcalic exhalation, belonging to volcanic arc type silicalite.

在硅质岩方面：冈底斯构造带侏罗系硅质岩主要属泥质硅质岩，在各个碰撞结合带和弧后盆地中均有产出，主要的产出状态有：①在碰撞结合带中呈岩块产出，构成蛇绿混杂岩的重要组成部分，属蛇绿混杂岩型硅质岩；②在弧后或弧间盆地中呈厚度不等的泥质硅质岩夹层产出，常具"硅灰泥"特征，属弧后深水盆地型硅质岩；③呈夹层状产于弧火山岩系中，属火山热液或火山喷气型硅质岩。

Magmatism in the form of volcanism and plutonism is predominant in the diwa maximummobility period which results in thick volcanic rock and all big intrusive bodies in the area.

岩浆作用(包括火山作用和侵入作用)在北京西山地洼激烈期中有强烈的表现，形成区内巨厚的火山堆积和大规模的侵入体。

But the volcano also produces a more deadly things: pyroclastic flow, that is composed of gas and rocks up to 1000 degrees Fahrenheit Clouds.

但火山还能产生一种更致命的东西：火山碎屑流，即由气体和岩石组成的高达华氏1000度的云状物。

Pyrocluster closes the gap between soft hazy 3D environment effects and puffy dense pyroclastic volcano clouds!

pyrocluster关闭火山云的差距软朦胧的3D环境效果和蓬松密集的火山碎屑！

The retreat of Rocca Bianca was at the top of a small mountain, which no doubt in former days had been a volcano--an extinct volcano before the days when Remus and romulus had deserted Alba to come and found the city of Rome

比卡山凹是在一座小山的山顶上，在从前这儿无疑的是一座火山，一座在雷默斯和罗默罗斯逃出阿尔伯，来建筑起罗马城以前就熄灭了的火山。

Some scientists have suggested that Toba caused the deep freeze and that perhaps such an event happening today could bring on a new ice age.

一些科学家们提出：是多巴火山引起了地球的深层冻结，假如当今有这样的火山爆发，或许会引起一个新的冰河时代。

Some 75,000 years ago a super-eruption from the site of Lake Toba in Sumatra blasted out more than two hundred cubic miles of ash over an area of over a million square miles.

大约75000年前，位于苏门答腊岛的一超级火山发生火山大爆发，其奔发出来的200立方英里的火山灰足以覆盖了一百万平方英里。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
