| Abstract: | Based on the principle of least squares techniques,adopting the method of curve fitting,successive fit is proceeded to the data of actual characteristic curve obtained by the performance measurement of the main fan and by comparison,a conclusion is drawn that to the characteristic curve of fan,adopting quintic multinomial to fit can get optimal effect. |
