注释- Lava was appropriately named by people living near Mount Vesuvius.The only active volcano on the European mainland, Vesuvius has erupted frequently since Pompeii and Herculaneum were buried by it ina.d. 79. The Neapolitans who lived in the vicinity took a word in Italian,lava, meaning "a stream caused suddenly by rain,” and applied it to the streams of molten rock coming down the sides of Vesuvius. The term was then taken into Standard Italian,where it came to mean the rock in both its molten and its solidified states.The Italian word in all its senses was borrowed into English around the middle of the 18th century (1750 being the earliest date of record).火山岩这一恰当的名称是由生活在维苏威火山附近的居民命名的。维苏威火山是欧洲大陆唯一的活火山，自从公元 79年庞贝和赫库兰尼姆被它埋没以来，它一直频繁爆发。 生活在附近的那不勒斯人用意大利语中的一个单词lava 指代从维苏威火山上流淌下来的熔化岩石流，而这个词的本意是“由雨水骤然形成的溪流”。 这一词语被纳入标准意大利语，意为处于熔化或凝固状态的岩石。大约在18世纪中期，这一意大利单词和其含义都被借用到英语之中（最早的记录见于1750年）
