The results showed that the main flow rolled up the leakage flow of the tip clearance and generated the tip leakage vortex.

结果表明：叶顶间隙气流与主流发生卷吸而生成泄漏涡。

Suppressed by the up passage vortex at upstream side of blade, the intensity and scale of the tip clearance leakage vortex is decreased.

渐缩型间隙在叶片前半轴弦受到上通道涡的抑制，减少了叶顶间隙泄漏涡的强度和范围；
