| 1 | DEM speedup: Stiffness effects on behavior of bulk material显示文摘A number of techniques exist for minimizing the computational cost of discrete element simulations(DEMs). One such method is a reduction of particle stiffness, which allows for bigger time steps and therefore fewer iterations in a simulation. However, the limits and drawbacks of this approach are still unclear, and may lead to invalid results. This paper investigates the effect of a stiffness reduction on bulk behavior by examining three case studies. Two cases demonstrate that particle stiffness can be reduced without affecting the bulk material behavior, whereas the third test shows that a stiffness reduction influences the bulk behavior. | Stef Lommen Dingena Schott Gabriel Lodewijks | 2014 | Particuology2014，12，1： | 11 |

| 5 | 益生菌对青年蛋鸡生长性能的影响显示文摘蛋鸡产蛋性能与很多因素相关,其中最重要的就是鸡群开产前的体重。高质量的青年鸡需要开产前体重达到或者超过品种设定的标准。但是在青年母鸡培育过程中经常会因为肠道梭菌等问题使鸡群的体重偏低,发育不良,导致后期生产性能下降。位于荷兰的一家企业(Het Anker公司)遇到了这样的问题。为解决该问题,该公司用益生菌(克洛生TM)来改善鸡群健康,试验共使用了62群鸡,31群空白对照,31群益生菌组,进行了近一年的试验,结果表明益生菌可以明显提高青年蛋鸡的平均体重,比该公司的蛋鸡12周龄标准体重高32 g/只,比空白对照组鸡群高19 g/只。不仅如此,克洛生还能提高鸡群的均匀度,为后期的高产打下良好基础。 | Stef De Smat 肖建根 黄广明(校) 罗正(校) | 2014 | 饲料工业2014，35，3： | 2 |
