使具有金属性质

Schematic mould is to be used at making the material such as metal, plastic, balata, glass has the tool of proper form and property.

概要模具是用于使金属、塑料、橡胶、玻璃等材料具有一定外形和性质的工具。

Among the various conductive fillers, carbon fibers have been proved to be a good candidate for EMI shielding. However, the electrical resistivity of a carbon fiber is much higher than the metal filler, so it must to use a greater number of carbon fibers in order to achieve the same shielding effect. In recent years, the Electroless plating is the new techniques of surface treatment of carbon fibers used to improve the electrical conductivity of carbon fiber. The copper-coated and nickel-coated carbon fibers have been proved to be a good candidate for EMI shielding.

导电高分子填充材料多使用碳纤维、碳黑及金属粉末，其中碳纤维具有高导电性、低密度及复合材料之补强特性，故本研究碳纤维作为填充材料，将碳纤维经过无电电镀处理，使其表面分别披覆金属镍及铜，增加碳纤维之导电度，混掺於聚丙烯高分子基材中，制成具有电磁波屏蔽功能之高分子复合材料，研究不同高分子成型方式与金属镀层对於碳纤维电学性质及复合材料电磁波屏蔽效益之影响。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
