介绍了目前关于共生星的模型和演化的理论。

In addition , the evolution of symbiotic stars and symbiotic binary models are briefly presented .

共生星的理论研究

The Theoretical Study of Symbiotic Stars

第二部分是对共生星的红外分类及演化的研究。

The second part is our study on the infrared classification and evolution of symbiotic stars .

本论文综述了共生星的观测特性和理论研究现状，并详细介绍了本人在攻读博士学位期间在共生星理论研究领域的工作。

In this thesis , we summarize recent observational properties and theoretical study on symbiotic stars , and present the results of our studies on the field .

利用星族合成方法，我们分别对半相接共生星、分离共生星和D-型共生星作了理论研究。

By means of a population synthesis code , we have carried out a theoretical study of semi-detached symbiotic stars , detached symbiotic stars and D-symbiotic stars .

这两种方式产生的半相接共生星的性质大不一样。前者在银河系中的诞生率和数目分别是～0.056&0.045yr~（-1）和～5颗；

To the first case , the birthrate of symbiotic stars is ~ 0.056 & 0.045yr ~ ( - 1 ) and the number is ~ 5 in the Galaxy ;

共生星双星是一颗有强大星风物质损失的红巨星与一颗早型热星组成的特殊双星系统。

The symbiotic binary is a special system , consisting of a hot early type star and a cool late type supergiant with strong stellar wind , which forms an expanding envelope .
