Fourthly, based onour experiments and the literatures', the necessities of endohedralmetallofullerenes' formation are the existence of well graphitized of carbonand metal acetylide.

四在实验和文献报导的基础上，提出原料中完好石墨化的碳和电石型金属碳化物的存在是形成Fullerene笼内金属包合物的必要条件。

And nearly 50 percent reduction of activation energy ,has obtained with the catalyst polypropylene ratio of 30%.

说明粉煤灰和电石渣对聚丙烯裂解具有一定的催化效果。
