supersaturation degree的用法和样例：
例句
- The supersaturation used is too low to produce an appreciable rate of nucleation.
所用的过饱和度太低，不能产生一个值得重视的成核率。 - The main evidence for the validity of nucleation theory rests on its ability to predict closely the critical supersaturation for most liquids in cloud chamber experiments.
成核理论正确性的主要证据在于它能在云室实验中精密地预测多数液体的临界过饱和度。
