恒星物质的不透明度

简介介绍了恒星物质的透明性质在恒星结构、演化、振动等许多恒星物理基本问题研究中的重要性和决定恒星物质不透明度的物理过程，回顾了第一代不透明度数据ＬＡＯＬ的发展历程与存在的问题，介绍了新一代不透明度数据ＯＰＡＬ的发展和目前观测与理论之间依然不一致的地方。

Opacity for Stellar Matter

Opacity for stellar matter is of fundamental importance in the study of many basic problems of stellar physics, such as the stellar structure, evolution, and oscillations. The physical processes which determine the stellar opacity are briefly introduced, and the history of the widely used opacity data, LAOL, is reviewed, laying special emphasis upon its applications to problems of the stellar structure and pulsations, which have been solved and have not been solved. Then the newly published opacity data, OPAL, are discussed concerning its physical improvements over the LAOL and its successful applications to problems which can not be solved by the LAOL, and the still unsolved problems in the stellar physics are mentioned as well.
