The experimental results show that with the increase of cascade solidity, the cascade loss increases at most incidences.

结果表明，随叶栅稠度的增加，叶栅损失在大部分冲角下呈增高的趋势。

Based on the straight cascade and the fan cascade, the design parameter of aspect ratio, maximum relative thickness and solidity were remodeled by programmed design method.

在原直叶片与三维风扇叶片的基础上，通过编程设计手段改变其设计参数，使得叶片的展弦比，最大相对厚度与稠度等参数发生改变。
