火山爆发

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。

A new study puts to rest questions about whether Toba plunged Earth into a 1000-year deep freeze and whether an equivalent event today could jump-start a new, millennia-long ice age.

对于多巴火山喷发是否将地球带入了历时千年的深寒期，现在同等规模的火山爆发是否会引起新的千年冰川期等疑问，一项新的研究给出了否定答案。

As volcano eruption is deemed to be an uninsurable risk, there are few studies to turn to.

因为现在认为火山爆发是不可投保的风险，所以有关火山喷发的研究甚少。

The rate of volcanic eruptions as a model of the modern deformation constraints; collection and analysis of regional faults, geophysical and seismic data and the Cascadia region are given a series of maps of the region in order to understand the complexity of the organization structure; monitoring of Oregon and Washington areas and earthquake Volcanic activity.

将火山爆发速率作为现代变形模型的约束条件；收集和分析区域断层，地球物理及地震资料并给出Cascadia地区的系列地图以了解该地区的复杂构造组织；监测俄勒岗和华盛顿地区的地震及火山活动。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

矿石中天然固有的杂质严重影响其后来的质量。矿石的形成是地质变迁的结果，包括地壳运动，火山爆发，沉积作用，冰河作用和风化等等，在这些作用下，生成了火成岩，火山杂岩，水成岩和沉积岩等，一些矿石是由于这些作用共同形成的，这就是自然界中没有纯净矿石的原因。由于这些原因的存在，需要用分离技术和器械，也就是矿石加工设备对矿石进行的分割，迄今为止这些矿石加工设备已经不能够满足冶金工业的需要，科学家们力图用激光把冶金工业提高到一个新的水平。

没有什么比矿石形成之前就存在的杂质对矿石品质的影响更为重大。矿石是火成岩、火山群、水成岩、沉积岩等成形时，在包括地壳运动、火山爆发、沉积、冰蚀、风化等地质变化的作用下而形成的。而有些地质变化在一个发展阶段中存在共生现象。自然界无杂质岩石缺乏的主要原因在于需要分离技术和设备来完成，即：需要选矿设备和装置。而迄今为止，这些设备还难以适应冶金业的需要，虽然科学家们尽一切努力用激光分离技术将冶金业提高到一个新的高度。

影响矿石质量的关键是其所含杂质的多少，其成色高低受一系列地质变迁，如地壳运动，火山爆发，沉积运动，冰川运动及风化侵蚀等作用影响，经过高温成岩，火山熔岩，含水岩，水成岩等过程形成，部分以共生态存在。自然界纯矿石稀少，因此我们需要使用分离技术和设备，即筛矿装置和器械，但目前的设备已不能满足冶矿业的需求，科学家们正试图以激光筛选使选矿技术达到一个新的水平。

Such sights are uncommon as many eruptions simply see ash and rock blasted into the sky.

这种景观对于斯特龙博利火山来说不是常见的。以前斯特龙博利火山爆发时只是出现火山灰和岩石喷上天空的景象。

After the volcano exploded 18 hours, volcanic chippings buried the city of Pompeii. The deepest is about 19 meters. In this way Pompeii suddenly disappeared in its top period of material civilization.

火山爆发18个小时后，火山碎屑将整个庞贝城掩埋，最深处竟达19米，庞贝就这样突然消失在它物质文明的巅峰期之中。

Pavlof Volcano blasts clouds of ash and steam to a height of about 18,000 feet (5,490 meters) over the Alaska Peninsula during an August 2007 eruption.

在07年8月的一次火山爆发中，Pavlof火山向阿拉斯加半岛上空喷出的火山灰及水蒸气可高达约18，000英尺（5，490米）。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
