摘　　要：近10多年来地面燃气轮机技术迅速发展,其中一个重要方面是燃气轮机效率的提高。燃气轮机效率的提高与涡轮进口温度的提高、压气机涡轮气动特性的改进以及先进联合循环的使用分不开。本文通过对燃气轮机简单热力循环工作过程的分析,讨论了这些因素对燃气轮机效率的影响,并且简要介绍了近10多年来国内外在这些方面为提高燃气轮机效率而采取的一些措施。Recently, it is the tendency that many countries are setting up more and more gas turbine electric power stations, in order to optimize their countries＇ energy structure and protect the environment. This is a great stimulation for the development of the technology of gas turbine. These developments can be shown by the increase of the efficiency, which is closely related to the increase of TIT（ turbine inlet temperature）, the progress of the performance of the compressor and turbine, the use of advanced thermal cycles. This article is to find out the relation between the factors and the efficiency of the gas turbine through analysis of the gas turbine＇s thermal process. Besides, this paper gives a brief introduction of some specific measures.
