这些小凹坑增添了金刚石颗粒的外表系数，成果使石墨化的速度加速。

These small pits cause an increase of the specific surface of diamond particles, which results in an acceleration of graphitization.

所有石墨化元素均降低介稳定共晶温度，而提高稳定共晶温度，并使两者间距扩大。

All graphitizing elements decrease the metastable eutectic temperature, increase the stable eutectic temperature and enlarge their distance.
