/ˌhʌmfri ˈdeɪvi/
- (1778-1829) an English chemist who was one of the first scientists to make use of electricity to break chemical compounds into their separate elements. Between 1807 and 1808 he discovered six chemical elements, including calcium, potassium and sodium. However, he is better known for a practical invention that saved many lives: the Davy lamp, a safe lamp for use in coal mines. This was widely used in mines until it was replaced by the electric lamp in the 20th century.
汉弗莱·戴维（Humphrey Davy）：（1778-1829）英国化学家，是最早利用电将化合物分解成单独元素的科学家之一。在1807年和1808年之间，他发现了六个化学元素，包括钙，钾和钠。但是，他以拯救许多生命的实用发明而闻名：戴维灯，一种用于煤矿的安全灯。在20世纪被电灯取代之前，它已在矿山中广泛使用。
