Chad: The small round pieces of paper waste produced during the production of punch ed paper tape and punch cards.

孔屑：纸带或咭在打孔时所产生的圆形纸屑。

A punched tape wherein only partial perforation is completed and the chad remains attached to the tape.

一种穿孔带，打孔时紧紧完成部分穿孔，而孔屑仍附着在打孔机上。

The environmental factors such as air temperature and humidity also affect the putrefaction and decomposition of plant litter, and the rise in air temperature and the increase in humidity will enhance the decomposition of plant litter by microbes.

环境因素对藨草残体的腐烂分解有着十分重要的影响，温度升高、湿度增大，则加速微生物对植物碎屑的分解。

Most people can easily escape the lava flow, pyroclastic flow, but escape is not so easy.

人们可以轻易地躲开大部分的熔岩流，但躲避火山碎屑流却不那么容易。

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。

Pyroclastic rocks are a kind of transitional and complex rocks between lavas and sedimentary rocks.

火山碎屑岩是介于熔岩和沉积岩之间的过渡类型岩石，岩类复杂。

Its volcanic geological formation is complicated, varying from hard lava magmas to weathering pyroclastic debris.

火山形成的地层非常复杂，从坚硬的火山熔岩到松软风化的火山碎屑堆积物都有存在。

On the basis of the past schemes, new classifications of pyroclasts and the petrographic as well as the petrogenetic classification of pyroclastic rocks are proposed in this paper.

中国学者提出的火山碎屑岩分类时间较早，有自己特色，在一定的范围得到了应用。

The author deals with mainly the sequence and distribution of the pyroclastic deposits of the 800 a. B. P. eruptions.

主要论述了这次大爆发的火山喷发碎屑堆积物的层序和分布。
