And as different degrees of industry were apt to give men possessions in different proportions, so this invention of money gave them the opportunity to continue and enlarge them: for supposing an island, separate from all possible commerce with the rest of the world, wherein there were but an hundred families, but there were sheep, horses and cows, with other useful animals, wholesome fruits, and land enough for corn for a hundred thousand times as many, but nothing in the island, either because of its commonness, or perishableness, fit to supply the place of money; what reason could any one have there to enlarge his possessions beyond the use of his family, and a plentiful supply to its consumption, either in what their own industry produced, or they could barter for like perishable, useful commodities, with others?

就像不同程度的勤劳会给人们不同数量的财产，货币的发明也给予了他们机会去保存和扩大货币。想象有这么一个岛屿，与世界其它地方的贸易完全隔绝，在那里只有一百户家庭，但是有绵羊，马和奶牛，和其它一些有用的兽禽和有益健康的果实，以及足够生产十万倍谷物的土地，可是，由于这些物品不是太过普遍就是易于腐烂，岛上竟没有一样东西适合做货币；在这种情况下，那里的任何人在超过他的家庭所需，以及通过自身的劳动生产或与他人物物交换一些类似的易腐的有用的日用品之外又有什么理性去扩充他的财产呢？

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。

The rebounding damping technology, that the function in the same kinds of products sold in the market are not in common, means when you pull the drawer out to the bottom, it will has a process of soft closing and rebound, which can reduce the noise made by the things loaded in the drawer in efficiency. Moreover, because of the variable damping technology, which help to lessen the force of of the inertia made by the motion of the box when open or close it, and it will extend the useful life of the cabinet effectively. Therefore, it proved that the two-way slow motion cabinet have a longer useful life than the single soft-closing drawer system. And that is the reason why GRASS HOPPER is so popular in many countries all over the world.

反弹阻尼技术就是当你的橱柜抽屉拉到尽头时，有一个轻微的缓冲反弹过程，这样就减小了抽屉里面的装载物的碰撞声音，能达到更加实际意义上的静音，同时由于具备这种功能，在开合抽屉时就大大减小了由于抽屉的运动惯性对柜体产生的破坏力，这样就有效的延长了橱柜的使用寿命；所以使用双缓冲抽屉的橱柜比使用单缓冲抽屉的橱柜寿命明显延长，而市场上还没有具备这种功能的同类产品。
