摘　　要：对某多级轴流压气机进口导叶加前两级进行了数值分析,针对其叶列间匹配不合理的情况,进行了导叶的扭曲改进设计。计算结果表明,这种改进方法能明显提高机组效率。The aerodynamic performance of a five-blade-row（ Inlet Guide Vane-Zero Stage-One Stage）compressor were simulated and the results were thoroughly analyzed. Aiming at the inconsequence of the matching between the blade row, the improved design of twist vane were done and increased obviously the compressor efficiency.
