“…For gas-phase crystal growth, u can be expressed as an index, log (Q / K)k, where K is the equilibrium constant for phase, k, at a given temperature and pressure and Q is the activity quotient of k (Symonds et al, 1987;Symonds and Reed, 1993). Since the nucleation rate increases with a (Piekarczyk, 1987), the implied higher nucleation rates at lower temperatures suggest that a increases with decreasing temperature.…”

“…At lower tem peratures, the number of crystals increases, which implies higher nucleation rates. One of the main factors controlling the nucleation rate is the degree of supersaturation (Piekarczyk, 1987). The degree of supersaturation is expressed in terms of the parameter a.…”

“…[43,50] [45] Der groûe Vorteil des Modells des kooperativen Transports gegenüber anderen Modellierungsansätzen (¹e-Bezie-hungª, [13,46] ¹Vierstufenmodellª [47,48] ) [67] liegt nach unserer Erfahrung in der einfachen Behandlung von Transportsystemen, in denen die Bestandteile eines mehrphasigen Gleichgewichtsbodenkörpers nacheinander von der Quelle zur Senke transportiert werden (¹nichtstationäres Transportverhaltenª). Zur Modellierung solcher Experimente schlieût sich an S 1 eine erneute Quellenrechnung, Q 2 , an.…”
