采用喷雾干燥-固定床法制备碳化钨粉末，研究了喷雾干燥和碳化反应温度对制备偏钨酸铵前驱体以及碳化钨的影响，前驱体粉末呈现均匀的球状形态，平均粒径为10~20μm，喷雾温度对影响粒径大小和分布影响小；400℃的进口温度下进行喷雾干燥，喷雾粉末仍然保持偏钨酸铵原来的基本组成不发生分解。

The shredding of agro-residues, such as corn stalk, straw, wood sawdust and other herbaceous biomass, were investigated in this dissertation. According to the machinery mechanics of shredding, the components, shearing strength and pressive strength of the biomass were analysed in theory, which played a critical role during the shredding process. And the powder was examined by Scanning Electron Microscopy. It was founded that shearing,splitting and grinding force were appropriate for shredding biomass. The results also showed that primary shredding was the bulk shredding model, which was mainly affected by shearing and splitting force, therefore the curly knife and the straight knife were useful; while the fine shredding was the surface shredding model, affected by splitting and grinding force, and the straight knife useful.

本文以农林废弃生物质为研究对象，结合机械力破碎基础理论，从影响其破碎的化学组分和剪切强度、抗压强度等力学角度进行了理论研究，并运用扫描显微镜对破碎产物的微观结构进行了实际分析，结合二者得出如下结论：最适合生物质的施力方式为剪切力、劈碎力和磨削力；生物质粗破碎为体积破碎，主要受剪切力和劈碎力作用，刀片宜设计成弯口刀和单面直刃刀；细破碎为表面破碎，主要受剪切力和磨削力作用，刀片宜设计成双面直刃刀。
