摘　　要：测量了较大间隙 (τ =0 .0 36 )下常规直叶栅中分面和上下游及栅内的气动参数 ,并与黄洪雁博士测量的较小间隙 (τ=0 .0 2 3)下相同叶栅的试验数据进行了详细比较 。The airflow parameter in the conventional straight cascade with bigger blade tip clearance(τ=0.036) was measured in detail.The experiment result was compared with that measured by PhD Huang for smaller blade tip clearance(τ=0.023).The effects of tip clearance in clearance flow and blade cascade performance were discussed.
