摘要(Abstract)：
对一种单圆弧叶型多叶风机与 4种双圆弧叶型多叶风机进行了系统性试验研究。研究表明具有较大圆弧半径的双圆弧叶型多叶风机具有良好的空气动力特性与低噪声特性
The systematic tests of a single\|arc blade profile multiblade fan and four dual\|arc blade profile multiblade fans are made. It is showed that the dual\|arc blade profile type which blade is of bigger radius than others appears to have better aerodynamic characteristic and low\|noise characteristic.
