为了寻找行踪不定的次原子微粒——中微子，费米实验室的研究人员去年进行了MiniBooNE研究，宣称他们发现了非常反常的现象。

Last year researchers involved in Fermilab's MiniBooNE study, which detects elusive subatomic particles called neutrinos, announced that they had found a surprising anomaly.

第二次喷发融化了大量的冰川冰，使岩浆冷却碎裂成砂质玻璃微粒，被上升的火山灰柱带走。

The second eruption, however, melted a large amount of glacial ice which then cooled and fragmented lava into gritty glass particles that were carried up with the rising volcanic plume.
