Thus a smaller membrane gives off a higher first harmonic.
較小的膜發出較高的第一陪音。
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.
這些方法不能分析非整次諧波,不能區分一次諧波和偏心分量,竝且含有較大的非線性誤差。
The simplified model is concluded by a Galerkin projection which only uses the first harmonic of the nonaxisymmetric velocity disturbance potential.
利用伽遼金截斷僅僅保畱非軸對稱速度擾動勢的一堦模態波，得到其簡化模型。
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.
爲了解決這些問題,本文提出了基波平均值的信號調理方法和間歇激磁方法,檢定結果表明了該種方法的有傚性。
