qpo怎么记

Secondly, aiming at the physical phenomenon that vibration of particles in fluctuating wind field, after setting the Nonlinear non-autonomous system model, we studied the dynamic characteristics of periodic vibration, period-doubling bifurcation, QPO, chaos and so on.

其次，针对颗粒在风场作用下来回振动这一物理现象，本文通过建立非线性非自治系统模型并求解，对颗粒的周期运动，倍周期分岔，准周期运动，混沌等动力学特性进行了研究。

The theory of Quasi-periodic Oscillation ( QPO) in Low-mass X-ray Binaries ( LMXB) is discussed in this paper. Beat-Frequency Models ( BFM), including development, are presented in detail.

本文简略地叙述了低质量X射线双星中准周期振荡（QPO）现象的理论解释，对其中的差频模型（BFM）和它的一些发展作了较为详细的介绍。

QPO is believed to be an effective approach to detect the accretion process near BHs since its time scale is equivalent to the dynamical time scale in the inner region of an accretion disk.

由于其时标与黑洞吸积盘内区的动力学时标相当，QPO被认为是探测黑洞附近吸积过程的有效途径。
