degree of freedom

1.Incomplex systems with many degrees of freedom such as peptides andproteins, there exists a huge number of local-minimum-energy states.

日的工作还是非常地细致，科研素养令敬佩。

2.Based on the correlation principle, an algorithm to decomposite the damped free vibration signals of a two degrees of freedom system with close natural frequencies is put forward.

摘要基于单一频率成分的自由衰响应信号的相关性原理，提出了一种频率密集成分的两耦合子自由衰响应信号的解耦算法。
