摘　　要：提出了用偏最小二乘法解决离心式风机调节性能的多元非线性曲面拟合问题 ,在此基础上建立了新型优化数学模型 ,并给出了具体的求解步骤 ,最后以简易导流器调节的 4- 73风机为例 ,建立了较高精度的调节性能模型 。The problem of the multi members and nonlinear mathematical curved surface imitation of regulating characteristic of centrifugal fans is proposed.The method based on the partial least square theory of regulating characteristic of fan is used. A 4-73 fan regulated by the simple adjusters is given for example , the model of regulating characteristic with high precision and wide applicability is set up and evaluated.
