用双星技术(Binary-technique)的谱线分析方法来测定双星系统中的红巨星或红超巨星的星风 物质损失率是目前最为精 确的。扼要介绍了此类方法的一般原理以及在ζAur/VV Cep双星系统的物质损失测量中的应用。同时介绍了该 方法的最新进展，并展开与此有关的一些简要讨论。
The binary-technique is the line profile analysis method which is the most accurate one being applied in a ζAur/VV Cep binary system to detect the mass-loss-rates of the stellar wind of the red-giant or of the red-super-giants. The principle and the recent development of the binary-technique are briefly explained in this paper. Furthermore some other things we considered are discussed.
