摘　　要：分子云的物理环境对恒星的形成率有重要的影响,而了解恒星形成对行星的形成和星系的演化有很大帮助。主要回顾了近20年,银河系及其近邻星系中恒星形成与气体之间的关系(即恒星形成定律),希望可以更好地了解恒星形成的本质,认识恒星形成与气体之间的关系以及恒星是否在以统一的方式形成。介绍了星际介质的组分与测量星际介质密度和恒星形成率的方法。重点综述了从星系尺度到分子云尺度致密气体与恒星形成率之间的关系,并对恒星形成定律的研究进行了总结和展望。The physical environment of molecular clouds has an important impact on the star formation rate,and understanding star formation is of great help to the formation of planets and the evolution of galaxies.This paper mainly reviews the relationship between star formation and gas in the Milky Way and the other galaxies in the past decade(that is,star formation law).Methods of measuring gas contents and star formation rates are also discussed.In order to understand the nature of star formation,whether there is any necessary connection between star formation and gas,and whether stars are forming in a unified way,this article focuses on the relationship between dense gas and star formation rate from the galactic level to the individual molecular cloud level.At the same time,the composition of the interstellar medium and the method of measuring the density and star formation rate of the interstellar medium are also introduced.
