表2 h与T、液相质量分数(fl)的关系

Table 2 Relations between h, T and mass fraction of liquid (fl)

Condition T fl h > hliq (Liquid zone) T = (h - L) / cp fl = 1 he < h ≤ hliq (Mushy zone) T = (h - Lfl) / cp fl=1-11-kpT-TliqT-Tm hsol < h ≤ he (Mushy zone) T = Te fl = (h - cpTe) / L h ≤ hsol (Solid zone) T = h / cp fl = 0
