中文摘要：

有高 graphitization 的双 walled 碳 nanotubes (DWCNT ) 被氢弧分泌物综合了。获得的 DWCNT 有两个的直径的狭窄的分布内部、外部的试管，并且在范围多于 DWCNT 的一半有内部直径 0.61.0 nm。到阳极的从 DWCNT 阴极的地电子排放被测量了，并且 DWCNT 的排放电流密度在大约 4.3 V/m 的一块应用的地到达了 1 A/cm2。在 DWCNT 的高温度的处理以后，长线性的碳链(C 链) 能在极端薄的 DWCNT 内被种形成新奇 C-chain@DWCNT nanostructure，证明这些极端薄的 DWCNT 是为准备有 one-atom-diameter 的真正一个维的 nanostructures 的适当 nanocontainer。

英文摘要：

Double-walled carbon nanotubes （DWCNTs） with high graphitization have been synthesized by hydrogen arc discharge. The obtained DWCNTs have a narrow distribution of diameters of both the inner and outer tubes, and more than half of the DWCNTs have inner diameters in the range 0.6-1.0 nm. Field electron emission from a DWCNT cathode to an anode has been measured, and the emission current density of DWCNTs reached 1 A/cm2 at an applied field of about 4.3 V/~tm. After high-temperature treatment of DWCNTs, long linear carbon chains （C-chains） can be grown inside the ultra-thin DWCNTs to form a novel C-chain@DWCNT nanostructure, showing that these ultra-thin DWCNTs are an appropriate nanocontainer for preparing truly one-dimensional nanostructures with one-atom-diameter.
