1.我们为了在理论上探索定向凝固蠕虫石墨的可能性来讨论:虫墨的结构是怎样的,虫墨如何中止生长,虫墨为何分叉,怎样才能做到:既极大地增加虫墨核心,又不致成球,不致于在虫墨生长过程中再碰到球墨核心而中止延伸,如何使虫墨长得苗条,在Ni-C合金中虫墨又如何生长等等,有些 1. In order to theoretically explore the possibility of directional solidification of worm graphite, we discuss: what is the structure of insect ink, how the insect ink stops its growth, why insect ink is forked, and how can it be done: , But also not into a ball, not in the process of growth of insect ink and then hit the core of the ink stop the extension, how to make the insect ink slim, in the Ni-C alloy insect ink how to grow and so on, and some
