摘　　要：利用一种有效而别致的双离子(N+和Ar+)辐照和热处理技术合成并焊接无定形碳纳米线(ACNWs).实验样品用高分辨透射电子显微镜(HRTEM)进行了表征证实,适当搭配的双离子辐照与热处理的结合将会引起多壁碳纳米管无定形化并导致相互交叉纳米线的焊接.此外碳结构相变中的原子演化也在目前已有的概念基础上进行了简单地讨论.A efficient and novel experimental method for synthesis and welding of amorphous carbon nanowires （ACNWs） by using double ion irradiations and heat-treatment is described. Experimental samples were characterized using high resolution transmission electron microscopy （ HR-TEM）. The results demonstrate that the proper combination of double ion irradiations and heat-treatment may make the multiwalled carbon nanotubes （MWCNTs） to become amorphous carbon nanowiro, thus enabling the welding of crossed ACNWs. In addition, the atomic evolution in carbon structural phase transformation is briefly discussed in connection with the current prevailing ideas.
