金蟲 (小有名氣)
| The terms asphalt and bitumen are often used interchangeably to mean both natural and manufactured forms of the substance. In American English, asphalt (or asphalt cement) is the carefully refined residue from the distillation process of selected crude oils. Outside the United States, the product is often called bitumen. Geological terminology often prefers the term bitumen. Common usage often refers to various forms of asphalt/bitumen as "tar", such as at the La Brea Tar Pits. Another term, mostly archaic, refers to asphalt/bitumen as "pitch". The pitch used in this mixture is sometimes found in natural deposits but usually made by the distillation of crude oil. |

asphalt 和 bitumen 沒有本質(zhì)區(qū)別。由于歷史,地理的原因,不同的名稱稱呼而已。兩個單詞可以互相通用。 Asphalt (US Listeni/ˈæsfɔːlt/ or UK /ˈæsfælt/,[1][2] occasionally /ˈæʃfɔːlt/), also known as bitumen (/bɪˈtjuːmən, baɪ-/),[3][4] is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product; it is a substance classed as a pitch. Until the 20th century, the term asphaltum was also used.[5] |
