  1. The results of the study on the processes of precipitation and the followed calcination indicated that the shape and size of the precursor influenced the product obviously. the precursors with shapes of bar or lamellar were obtained by controlling the reaction conditions, and accordingly, the product of nano - zno with different shape and size could be obtained

    對該法的沉澱反應和焙燒反應進行了研究，通過控制沉澱反應的工藝參數，可以得到不同尺寸的條狀和片狀前驅物，並對其進行了研究和分析；再經過對焙燒反應參數的調控，可以得到不同形態和尺寸的納米級氧化鋅，如球狀、網狀和棒狀。
  2. The synthesis process of single - wall carbon nanotubes ( swnts ) by catalytically chemical vapor deposition ( ccvd ) was investigated and the product was characterized with transmission electron microscopy ( tem ), electron diffraction ( ed ), electron dispersive spectra ( eds ) and raman scattering spectra etc. pyrolysis of methane over solid catalysts prepared with impregnation, ion - adsorption precipitation, and sol - gel technique can all lead to the growth of swnts

    本文研究了單壁納米碳管的化學氣相沉積法（ cvd ）制備工藝，並運用透射電子顯微鏡（ tem ） 、 x - ray能譜（ eds ）與喇曼（ raman ）光譜等分析手段，對產物及催化劑進行了表徵。採用浸漬法、吸附沉澱法與溶膠凝膠法等制備了催化劑，併合成了單壁納米碳管。
