The time series of temperature are expected to be the longest possible so as to examine various modes of oscillation periods.
人们希望温度的时间系列尽可能地长，以便能研究各种波的振荡周期。

We've done this before-- this is the conservation of energy, and in order to find the period of the simple harmonic oscillation, we take the time derivative.
以前算过-,这是能量守恒，为了算出,简谐振荡的周期，我们求时间导数。

While impulse forces not acting on the centroid, the influence of accessional attack Angle oscillation amplitude, impulse force scale and function time interval on range correction was discussed.
