By using chemical reduction-deposition method,a metallic nickel-decorated multi-walled carbon nanotube material,symbolized as x%Ni/CNTs,was prepared.

采用化学还原沉积法将少量镍负载分散到多壁碳纳米管(MWCNT,简写为CNT)上,制得一系列不同Ni载量的x%(质量百分数)Ni/CNT复合材料;利用多种谱学工具(如TEM,SEM、XRD、H2 TPD和CO TPD)对其物化性能进行表征,结果表明,所制得沉积镍颗粒粒径在～10nm量级;H2 TPD和CO TPD测试结果表明,经Ni修饰的CNT比单纯CNT对H2和CO具有更强的吸附活化能力,其所促进的Cu基催化剂对CO加氢成甲醇的催化活性比无CNT促进或单纯CNT促进的同类催化剂均明显提高。

In thesucceeding period of last 160～200 ka,which is to be divided at least four stages, plentifulsecondary speleothems and other cave formations,consisting mainly of calcite gypsum,aragonite and hydromagnesite,were accumulated.

其后１６～２０万年以来，约在四个主要时期形成了极其丰富的次生化学沉积物，其矿物组成主要是方解石和石膏。
