...P,就可得到利率发生微小变动时,债券价格变动的百分比,即: 麦考利久期与(1+R)的比值通常称为修正久期(modified duration,Dm): 这表明,修正久期可以看做利率发生微小变动时所引起的债券价格的变动水平。

“It’s something that needs to be adapted and modified before we could put it into use for long-duration space flight, ” Paddon-Jones said, “but I think the results are absolutely real.”
Paddon-Jones说:“它需要调试和改良,之后才能实际应用于长期空间飞行。 不过我认为结果完全真实。”
Anew approach, named Modified Fast Fourier Transform (MFFT), is proposed to analyze the components of a periodic signal when sampling duration is not equal to an integer multiple of the fundamentals.
提出了一种改进的快速付立叶变换(MFFT)的计算方法,在采样的持续时间不是信号周期整数倍的条件下,能够准确地提供此信号中各周期分量的特性。
