The main results of this study are summarized as folio wings : firstly , the effect of rare earth - doped catalyst to the synthesis of carbon nanotubes was systemic studied ; the vary of morphology and content of catalyst in the catalysis synthesis process of carbon nanotubes was also deeply investigated , which is helpful to the understanding of carbon nanotube growth mechanism 本文利用cvd和熔剂法及直接氧化法在合成和表征碳纳米管、硼基纳米材料及其他若干材料等方面做了以下初步的探讨： ( 1 )系统研究了稀土掺杂催化剂对碳纳米管生长的影响及催化合成碳纳米管过程中催化剂形貌和成份的变化，加深对碳纳米管生长机制的理解。
Experimental results show that the order of fluoride salt being put in and flux type also influences the phases constitution , morphology , distribution and absorbent rate of ti and b . the experiments on remelting master alloys and al or al alloys at a certain temperature range show that the phases constitution and size have a remarkable heredity 试验结果表明，不同的氟盐加入顺序和熔剂种类的不同也直接影响着中间合金中化合物的相组成、形态、分布以及中间合金中ti 、 b的实收率等。在用纯钛颗粒法制备中间合金时，熔炼温度的改变只能影响tial _ 3晶体的尺寸大小，而无法改变其形态。
The conventional methods of the gemmology and the modern instruments of electronic probe , ultraviolet - visible spectrophotometer , fourier transform infrared spectrometer , cathodoluminescence spectrometer are used to research and analyse the flux - grown synthetic spinel and compare them with the natural spinels 摘要采用常规的宝石学研究方法以及电子探针、紫外可见分光光度计、傅里叶变换红外光谱仪和宝石阴极发光光谱仪等现代测试仪器，对助熔剂法合成尖晶石的宝石学特征进行了全面分析，并与天然尖晶石进行了对比。
The results showed that the melting ratio of silica flux decreases and the complete melting time prolongs with the size of silica flux and matte grade increasing , and the effect of the blowing air and oxygen enrichment is not remarkable in the high grade copper matte converting process 对于高品位冰铜转炉吹炼，鼓入气体流量和氧浓度对石英熔剂熔化率影响不显著；熔剂粒度和冰铜品位对熔化率影响显著，并随着熔剂粒度和冰铜品位的增加，熔剂熔化率降低，完全熔化时间延长。
