VEI have begun to research on the discharge mechanism and insulation characteristic of pressure air.
VEI从上个世纪中期开始便对压缩空气的放电机理及其电气绝缘特性进行了积极研究。
An eight-point scale called the "volcanic explosivity index" (VEI) allows you to compare eruptions and volcanoes.
你可以通过“火山爆发指数”(VEI)来比较喷发和火山，它把火山爆发分为8个等级。
The so-called Oruanui eruption was the most recent volcanic event to score the maximum 8 on the VEI – 10 times bigger than Tambora, and 100 times bigger than Krakatoa.
在这里的所谓奥努伊（Oruanui）喷发是最近的得分最高的火山事件，是10分的火山爆发指数（VEI）中得了8分，比坦博拉火山爆发要大些，比喀拉喀托火山爆发大100倍。
Kikai weighed in at 7 on the standard volcanic explosivity index (VEI), which runs from 1 to 8, VEI 8 being reserved for the sort of mega-eruptions that cause ice ages and mass extinctions.
Kikai火山的标准火山爆炸性指数(VEI)为7。ve I分为1到8八个等级，而VEI 8则用来描述那种造成冰期和大规模灭绝的火山爆发。
Reasons to worry: Santa María's last big blast was one of the four largest volcaniceruptions in the 20th century, registering a VEI magnitude of 6 and leaving a 700-by-1,000 meter craterbehind.
列入关注的理由：20世纪四次最大规模的火山爆发，圣塔玛里亚就占了一次，记录的火山爆发指数(VEI)为6级，留下了一个直径为700-1000米的火山口。
