A physicist's creation of muon tracks in a cloud chamber,

物理学家在云室里创建的μ介子轨迹，

Small mixing cloud chamber with liters cubage has been used in the observation of the nature ice nuclei and the detection of the nucleating effectiveness of artificial ice nuclei.

小型混合云室常用于自然冰核浓度的观测和人工冰核成核率的检测。

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。
