Thus a smaller membrane gives off a higher first harmonic.
较小的膜发出较高的第一陪音。
These methods can't be used not only to analyze the non integral order harmonics,but to distinguish the eccentricity and the first harmonic,and contain the lager nonlinear error.
这些方法不能分析非整次谐波,不能区分一次谐波和偏心分量,并且含有较大的非线性误差。
The simplified model is concluded by a Galerkin projection which only uses the first harmonic of the nonaxisymmetric velocity disturbance potential.
利用伽辽金截断仅仅保留非轴对称速度扰动势的一阶模态波，得到其简化模型。
In order to solve those problems,this paper presents a signal conditioning method with the averaged value of the first harmonic and proposes an intermitted exciting mode.
为了解决这些问题,本文提出了基波平均值的信号调理方法和间歇激磁方法,检定结果表明了该种方法的有效性。
