并不是,测量一个周期,而是,测量10个周期,因为这样,不确定性减小,测量值的,相对误差减小。
But instead of measuring one period, I'm going to measure ten periods, because that gives me a smaller uncertainty, a smaller relative error in my measurements.
应用线化和校正方法,研究了单摆的非线性振动,作出了周期比和相对误差随摆角的变化曲线。
The vibration of the nonlinear pendulum is studied by means of linearization and correction method, the curves of the period ratio and the relative error is plotted.
利用逆散射理论,通过测量离体血管的声散射场振幅谱的大小周期,重构了猪的主动脉离体血管的内外半径,重构参数的相对误差<4%。
Inverse scattering theory was applied to reconstruct the inside and outside radii of the aortic blood vessels of a pig by scattering spectrum. The relative errors of reconstruction were less than 4%.
