type: PURPOSE
value: for perceptible growth rates
type: PURPOSE
Source sentences:
text: For perceptible growth rates, this mechanism requires a finite driving force (or degree of supercooling) in order to lower the nucleation barrier sufficiently for nucleation to occur by means of thermal fluctuations.
