纤维内部的石墨碳和外部的金刚石层有很大的不同。

There are two different contrasts related to interior graphite carbon and exterior diamond layer.

目的：观察石墨碳纳米颗粒对体外培养细胞的生长增殖、细胞周期及凋亡的影响。

OBJECTIVE: To investigate the effects of graphite carbon nanoparticles on cell growth, cycle, and apoptosis in vitro.

通过氧化、插层以及插层后加热可以在石墨碳层上引入极性基团，提高其比表面积，有利于高分子进行插层。

The intercalation of the polymer would be easier and the specific surface of the graphite would be enhanced while the graphite had been pre-processed.
