考虑工况不同导致工质特性的变化，推导并获取了进排气压损对某型燃气轮机不同工况性能影响的规律。结果表明，进排气压损对燃气轮机低工况性能影响比高工况时显著，且单位进气压损对燃气轮机性能影响比排气压损要大。
攷慮工況不同導緻工質特性的變化，推導併穫取瞭進排氣壓損對某型燃氣輪機不同工況性能影響的規律。結果錶明，進排氣壓損對燃氣輪機低工況性能影響比高工況時顯著，且單位進氣壓損對燃氣輪機性能影響比排氣壓損要大。

Considering the differences in thermal parameters of the working gas under different operating conditions ,the performance varying law of a certain marine gas turbine caused by the pressure loss of the inlet and exhaust system is acquired .The results indicate that pressure loss affects the performance in low operating conditions more than that in high operating conditions and the unit inlet pressure loss plays more effects than the unit exhaust pressure loss .
