| 摘要: |
| 5维以下复幂零李代数（不可分解的）在文献[4]中已经给出，本文将利用这一分类，给出它们的导子代数和上同调，并通过上同调来计算它们的2维中心扩张，最后，提出几个与中心扩张和上同调有关的问题 |

| Abstract: |
| nilpotent lie algebra of dimension 1-5 are classfied by Goze，and we compute derivation and cohomology，moreover，we can calculate central extension of dimension 2 with aid of cohomology |
| Key words: lie algebra,central extension,cohomology |
