The accuracy and efficiency of finite element numerical analysis have close relationship with the mesh quality and density distribution. In order to ensure the hexahedral mesh transition gradually and conformably, a set of 8-refinement based density control templates is proposed newly. The corresponding date structure and template application techniques are also given.

有限元数值分析的精度和效率与网格单元的划分质量以及疏密程度密切相关，针对三维六面体网格单元之间疏密过渡必须平缓和协调的要求，提出了一套基于8分法的六面体网格加密模板，并给出了相应的数据结构和模板应用方式。

Conductivity of foamed plastic is very different before and after foamed, which means the changes of carbon black congeries distribution caused by foam.

实验发现，发泡前后泡沫塑料的导电性有很大差别，说明发泡改变了材料中炭黑聚集体的分布状态。

The conductive powder is white and slightly gray and is non-toxic, light in weight and environment-friendly and also has less conglobation, good dispersity and repeatability and uniform size distribution; in addition, the particle size of the powder synthesized in different solvents is different and the minimum resistivity of the powder can reach 15 Omega cm and can be suitable for the various demands of products.

该导电粉体呈现白色并略显灰，无毒、质轻、环保、团聚少、分散性和重复性好，粒度分布均匀，在不同溶剂下合成的粉体粒径也不同，其电阻率最低可达到15Ωcm，可以适合不同的产品需求。

The hardness and wear resistance increase with increasing TiB2 content. Adding about 1.5%Mg in melt restrains the conglobation of the TiB2 particles, which makes the size of TiB2 particle decrease and the distribution of TiB2 particle is more homogeneous. The strengthening effect of TiB2 particles is enhanced and the hardness and wear resistance of composites are obviously improved. The excess Mg decreases the refinement effect of TiB2 particles, but the hardness and wear resistance are improved continuously.

结果表明：反应生成的TiB2颗粒平均尺寸约为0.5 μm，材料的硬度和耐磨性随着TiB2含量的增加而提高；添加1.5%Mg元素可明显细化TiB2颗粒，且使其分布更加均匀，增强TiB2颗粒的弥散强化和细晶强化效果，复合材料的硬度和耐磨性显著改善；过量的Mg元素(3%)会造成TiB2颗粒细化效果的下降，但其硬度和耐磨性能继续得到改善。

To Ming Dynasty, Pu'er had become the tea distribution center, Pu'er Tea officially went down in the historical book. Xie Zhaozhi in his "Yunnan Brief" said:"From officials to plebeians, all drink Pu'er tea". Fang Yizhi in his "Physics Knowledge" recored: Pu'er Tea was steamed into conglobation and sold to the Tibet market.

到明代，普洱已成为茶叶集散中心，普洱茶正式载入史书，谢肇淛在《滇略》中说"士庶所用，皆普茶也"，方以智在《物理小识》中记载"普洱茶蒸而成团，西蕃市之"。
