Like ethanol, butanol is an alcohol. That means each of its molecules contains an oxygen atom as well as the carbon and hydrogen found in an alkane.
和乙醇一样，丁醇也属于醇类，这说明每一个丁醇分子包括一个氧原子和直链烷烃里的那种碳原子、氢原子。

Any simple alcohol is composed of a number of carbon and hydrogen atoms (like a hydrocarbon such as petrol) together with a single oxygen atom.
任何一种简单醇类都是有大量的碳分子和氢分子(如同碳氢化合物，譬如汽油)以及单个氧原子组成。

The energy and the elliptical orbit of the electron in hydrogen-likeatom are derived from formula inverse square attraction and Sommerfeld's quantized conditions.
