The calculated results forthirty-one metals agree well with experiments.It has also been proved that by using the freeelectron model of melting, the fusion equationof metals is Simon equation (T_m/T_(mo))q=1+(p/d).Two parameters q and d, which have to fit withexperiments in Simon's empirical equation, nowcan be predicted theoretically, e.g. for Mg,giving q=1.56, d=7.88GPa, the calculated meltingcurve in a fairly wide pressure range (0~60GPa)is shown to be close to the experimental one. %K melting curve of metals %K free electron model
