从热力学的观点看，在熔点，晶相和非晶相达到热力学平衡，即自由能变化ΔG=0。
引入APP后，PP/APP复合材料的平衡熔点升高，结晶速率大幅度提高。
Because of the introduction of APP, PP/APP′s equilibrium melting point rose slightly and crystallization rate rose markedly.
计算结果表明，热脉冲作用下，转变时体系平均温度高于平衡计算熔点，结构转变是过热熔化过程，系统不可能发生从晶态到非晶态非平衡转变。
The results show that the average system temperature is higher than the calculated equilibrium melting point of cu while the transformation occurs which should be an overheated melting process.
