摘　　要：采用复合法制备型壳 ,在制备过程中 ,改变不同的环境湿度和温度而得到型壳的不同干燥时间曲线 ,确定工艺参数优化值。借助扫描电镜观察到细化的叶片表面的钴微粒形核核心 ,通过能谱分析手段 ,研究型壳内表层的白色物质的相组成。Using mold prepared by compound method, on the basis of different drying time curve attained by changing environmental humidity and temperature, the optimized processing parameters were determined. SEM was used to observe nucleation site of Co particles, and energy spectrum analysed phase composition of white matter in endosexine of mold.
