In this paper, the processes of electroless Ni-P, Ni-Fe-Co-P and Ni-Co-B platingwere investigated by using graphite pieces as samples first, and then Ni-P, Ni-Fe-Co-Pand Ni-Co-B coatings were deposited onto carbon nanofibers by using the selectedelectroless processes. The composition, structure of the coatings and the properties ofthe metal-coated carbon nanofibers were also studied.

通过综合测试研究，指出金山地区矿体的&黑色底板&实际上是一套富含石墨、硫化物的千糜岩，在客观地质环境中可以产生比较稳定的自然电场，形成氧化还原地电池。

If nitrogen is present as single atoms, it would hint that the diamonds were produced rapidly and at relatively low temperature - as might happen if the diamonds formed from pockets of graphite in the zircons in a single, rapid event. That would make the diamonds young.

如果氮元素被证实是以单个原子的形式存在，这意味着钻石是在相对低温的环境下快速形成的——对那些由锆石中的石墨矿囊转变成形的钻石来说，如果单一而快速的条件具备，这种情况就很可能会发生，并将证明这些钻石的年代并不久远。
