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.
