摘　　要：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。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.
