It is shown that polystyrene has been grafted on the surface of nmSiO2 particles and the grafting ratio is about 40%. The surface of nmSiO2 could be treated effectively by KH570in absolute ethanol at 25℃, 48h. The nmSiO2-g-PSt unpurified by toluene appear microsphere in which nmSiO2 particles are contained, whereas the purified one appear internet formed by many pieces. The grafting ratio of PSt on nmSiO2 surface could be influenced obviously by dispersion agents content and agitation speed, whereas the morphology of nmSiO2-g-PSt purified is rarely changed.

In the aspect of virtual unexpected events, focus on the shortage of existing flame model, paper proposes a random Lagrangian method based on non-grid, which through a group of particles to modeling the fluid. Its statistical properties and the equation based on fluid changes in the same particles, but more stable.

5针对虚拟火灾突发事件，鉴于现有火焰模型的不足，论文提出了通过一组粒子建立流体模型，它们的统计特性和基于流体方程变化的粒子相同，且在数值上比方程的确定性解更加稳定。

Such a viewpoint of the effects of a little water addition has never been reported, it opened a new way to product SWCNTs with high purity and low cost. On the ground of the experimental results and mechanism studies, a little water addition may open a way for using the natural gas as carbon source to manufacture SWCNTs. By analyzing XRD, XPS results and with comparative experiments, we concluded that the active phases of SWCNTs growth in Ar were small Fe particles. A little W species can improve the surface characters of support and increase the dispersion of Fe particles, but higher W loading will cause large quantity of WC, which decompose CH〓 to amorphous carbon.

本文根据W-Fe-MgO催化剂中间产物和粗产物的XRD、XPS测量结果，结合制备实验和对比实验指出：在Ar中1073K下，生长SWCNTs的活性相是Fe的小颗粒，少量W在催化剂中以氧化物形式对载体表面改性，起提高Fe分散度的作用，但W浓度过高时在反应过程中会生成大量WC，又会催化CH〓分解为无定形碳，造成产物中SWCNTs含量下降。
