摘　　要：用ＣＶＤ法生产碳纳米管时，裂解温度、裂解时间和原料气流量大小对碳纳米管的产率、形态有很大影响，其中以裂解温度的影响最大。适宜的裂解温度、裂解时间和原料气流量有利于提高碳纳米管的产率和产量。在一定范围内提高裂解温度。When carbon nanotube being produced by CVD,pyrolysis temperature,time and flow rate of source gas strongly affect the yield,output rate and morphology of carbon nantube,especially the temperature parameter. Suitable pyrolysis temperature,time and flow rate of source gas are of help to enhance output rate and fraction of carbon nanotube in raw products. Enhancing reaction temperature within certain range is beneficial to the production of carbon nanotubes with less structural and textural defects.
