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。

With regard to steal. Sometimes you are facing an enemy when the deal is behind orthe side of the sudden appearance of a knife will you engage in turn, this is nothing, only because the rules of the reasonsfor the Housing knife, some single-pole, that is, some group 1v1 knife NVN players because of the rules is spontaneouslydeveloped, so many new people do not know or completely do not care about the rules there, which so many people who abide bythe rules is very depressing!

关于偷。有时候你正面对一个敌人正在周旋的时候，背后或者侧面突然出现一把刀将你搞翻，这其实没什么，只是因为刀房规矩的原因，有的是单刀也就是1V1有的是群刀NVN由于规矩是玩家自发制定的，所以很多新来的人不知道或者完全不在乎有没有规矩，这就让很多遵守规矩的人很是郁闷！
