不久前Kritschmer,Huffman和他们的同事首先报道了一种新类型的碳分子——C_(60)和C_(70)的较大量制备方法。 我们采用了相似于Krtschmer-Huffman方法制备出C_(60)和C_(70),其合成方法的基本原理为:当强电流使两个石墨电极间
Not long ago Kritschmer, Huffman and their colleagues first reported a larger type of preparation of a new class of carbon molecules, C_ (60) and C_ (70). We use similar to the Krtschmer-Huffman method to prepare C_ (60) and C_ (70), the basic principle of its synthesis method is as follows: When the strong current between the two graphite electrodes
