free degree的用法和样例：
例句
- A degree of freedom is any quantity that can vary, such as a coordinate specifying a particle's location or one component of its velocity.
一个自由度是可以改变大小的任何量，例如标示某一粒子位置的座标，或粒子速度的某一分量。 - Because the stator consists of elastomer and piezoelectric ceramic, degree of freedom and physical field coupling problem need to be solved.
定子由弹性体和压电陶瓷两种材料组成，不仅存在自由度耦合问题，而且还存在不同物理场的耦合问题。
