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。

An hour later, in the woods on the south side of a path on the manor's east, dirty bookworm, Huo qing-feng, is going through the woods in festinating gait while ten Kui embroidery-clothed assassins are closely going after him. Even if he constantly tries to use those burn-feeling tags to halt them, the assassins fear no more because they had experienced the effect of tag once. Besides, Huo's position is being reported by four flying sun crows so he just can't escape from the chasers. This moment, he reaches the exposed path and feels no good about this so tries to rash into the opposite woods. However, a sun crow has dived to catch his shoulder. He grasps the crow's arm with the other hand and the crow instantly release his shoulder with a sharp cry. Nevertheless, Huo is hit down by another crow's rod then three assassins rash out from the woods and wields long hooks toward Huo. Huo's mouth opens wide and he thinks he will be hauled away like a weak hen. But, all of a sudden, several shines from weapon flashes and three long hooks are cut in a blink!

半个时辰之后，在山庄东侧一条小路南边林中，脏书生霍青锋正在树丛中慌张穿行，他身后不远有十个夔纹死士紧紧追著他—他虽然不断使用那种特殊符咒试图挡住追兵，可是这些死士有了经验已经不怕了，而且他的位置一直被飞在空中的四个金乌一族盯住，所以他难以逃脱，此时他从树林中来到小路上，正觉得不妙，想赶快再钻入对面树林，一个金乌已经俯冲下来抓住他的肩，他用另一只手捏住金乌的手臂，那金乌立刻怪叫了一声把手放开，可是他很快又被另一个金乌以棒打倒在地，之后三个死士从林中窜出，对霍青锋挥出长勾，他张大嘴巴，心想这回一定会像老母鸡一样被拎走，可突然寒光一闪，三柄长勾被一瞬间截断！

If the absorbance of the three process colors were correctly matched to the spectral response of the eye,printing cyan,magenta,and yellow on top of each other would absorb all of the additive primariesto produce black.In practice,overprinting these three colors creates a dark brown,so to enable a wider range of densities to be printed a black ink must also be used.The black also enhances the edges of an image and reduces the amount of expensive colored inks that need to be used.The four colors cyan,magenta,yellow,and black are often abbreviated as CMYK,with the last letter of the word black used instead of the first to avoid confusion with blue.Many people in the praphic arts industry refer to cyan and magenta as"process blue"and"process red"(or,confusingly,as just blue and red).As well as any pigment that may be present,substrates have other properties that affect color appearance.
