查询词典 cubic

The second part was to test the appearance, ingredient analysis, surface potential, thermal conduction properties, and magnetism of the nano composite fluid prepared from the parameters. The experiment found that unoxidized particles, Ag, Cu, Fe, and Ni appeared round. If combined with oxygen in water as oxides, the nano particles would grow toward certain directions. In copper/iron nano composite fluid, FeO appeared cubic, Cu2O appeared coniferous. In silver/iron nano composite fluid, FeO was polygonal. In dielectric potential detection, the nano composite fluid was likely to aggregate and deposit, except for silver/iron set. In other sets, the pH of silver/cobalt nano composite fluid was 7, surface potential was 21.21mV; the pH for silver/nickel nano composite fluid was 6.5, surface potential was 21.04mV; the pH for copper/iron nano composite fluid was 7, surface potential was -30mV. The fluid particles of the three sets could all maintain suspension of 2 weeks or more. For thermal conduction, the silver/nickel, nano composite fluid showed the best thermal conduction. Under temperature of 30℃ fluid weight conduction of 0.4%, the thermal conduction increase was 26%. For magnetic detection, except for silver/iron nano composite fluid, the nano particles of other three sets were paramagnetic, and all four sets were soft magnetic nano composite materials.

第二部分。将由较佳制备参数所产出的奈米复合流体，进行形貌外观、成分分析、表面电位及热传导性质实验与磁性检测；在奈米颗粒的形貌部分，经实验发现Ag、Cu、Fe、Ni等未氧化的颗粒皆呈现近似圆形，而若与水中的氧结合形成氧化物，奈米颗粒则会朝特定方向成长，在铜/铁奈米复合流体中FeO为四方体结构、Cu2O的颗粒是针叶状，在银/铁奈米复合流体中FeO则为多边形结构；而介面电位检测方面，结果显示经本制程所产出的奈米复合流体除银/铁奈米复合流体这一组较容易聚集沉淀外，其他三组中银/钴奈米复合流体的pH值为7，表面电位为21.21mV，银/镍奈米复合流体的pH值6.5表面电位为21.04mV而铜/铁奈米复合流体的pH值为7时表面电位约在-30mV，且此三组流体颗粒皆能维持悬浮性2周以上，悬浮性较佳；热传导实验部分，四组奈米复合流体中以银/镍奈米复合流体在增进热传上效果最佳，在温度30℃及流体重量浓度0.4﹪条件下热传导系数增进达26﹪；磁检测方面，除了银/铁奈米复合流体外，其他三组奈米颗粒皆属顺磁性，且这四组奈米复合材料都是属软磁性。

In chapter 2, we focus on derivation of the tortuosity models for flow of Newtonian incompressible fluid in two- and three-dimensional porous media with spherical, cubic and plate-like particles by applying the geometrical method. We first present the ideal geometrical models of porous media to show the ideal and representative streamlines based on the assumption that some particles in porous media are unrestrictedly overlapped and hence of different configurations, then the average tortuosity is derived by geometrically and weightedly averaging these representative flow paths.

第二部分采用几何分析法研究了二维和三维情况下的球形颗粒、立方体颗粒和板状颗粒多孔介质中流体流线的迂曲度，首先给出多孔介质的理想几何模型，通过分别考虑固体颗粒重叠时、不重叠时以及粒子的不同排列等情形时的流体流线，然后对这些理想代表性流线的迂曲度取几何平均和加权平均，最后推导出流体流过多孔介质的迂曲度解析表达式。
