  5. In this thesis, we will focus on the nanotube structure and synthesis, including disorder multi - wall carbon nanotube, aligned multi - wall carbon nanotube array, cnx nanotube, and bcn nanotube. the effects of growth parameters, which provide scientific basis for pyrolysis of carbon nanotube, were studied systematically. furthermore, layered aligned multi - wall carbon nanotube arrays separate by catalyst particles were synthesized on the surrounding of reaction quartz tube by injection of xylene - ferrocene for the first time, which provided a chance for the accurate measure and potential use of carbon nanotubes

    在對碳納米管制備的基礎上，全面系統地研究了碳納米管的影響因素，對熱解法制備碳納米管確定了可供參考的制備工藝參數，在些基礎上，首次成功地直接在反應爐內石英管壁上直接生長分層生長的定向碳納米管，為納米管的性質的測量提供了一定的基礎，而且為定向碳納米管在微電子學領域的應用提供可能性，能成功地實現定向納米管的固定長度生長。
  6. The field emission property of carbon nanotubes could be increased by substitution of nitrogen for some of carbon, however, however, that of bcn nanotubes was poor. 1. study of disordered multi - wall carbon nanotube carbon nanotubes with different diameter distributions have been produced by thermal decomposition of a ferrocene - xylene mixture under different temperatures and different catalysts in an ar ( or n2 ) / h2 atmosphere
