Both metals and plastics are good conductors of electricity D. Conductivity has nothing to do with the type of material 相关知识点: 试题来源: 解析 A。解析:在不同材料导电性实验后,发现金属线能很好地导电而塑料线不能。A选项说金属是电的良导体,塑料是绝缘体,符合实验结果。B选项描述与事实相反。C...
Furthermore, metals are quite strong, yet deformable,which accounts for their extensive use in structural applications. 科技英语在讲述科学真理的时候通常用主动语态。如:Metals are extremely good conductors of electricity Deformable? 译文:金属是十分好的电和热的导体,它们对可见光不透明;一个抛光的金属表面...
atoms. Many properties of metals are directly able to these electrons. 译文:金属材料通常由金属元素组成。它们有大量无规则运动的电子。也就是说,这些电子不是被约束于某个特定的原子。金属的许多性质直接归属这些不规则运动的电子。 Metals are extremely good conductors of electricity and heat and are not ...
electrodes are comprised of a metal conductor with a metal lead (sometimes the same material) for the conduction of electrical current. Different inorganic and organic materials including metal, polymers, carbon, as well as their composites thereof, have been used for electrodes on...

英语翻译1.Virtually all important properties of solid materials may be grouped into six different categories :mechanical ,electrial,thermal,magnetic,optical,and deteriorative.2.Metals are extremely good conductors of electricity and heat,and are not transparentto visible light;a polished metal surface ...
Capacity of the material to pass electric charge is known as electrical conductivity. Electrical resistivity is the reciprocal of electrical conductivity. Ohm metre is the unit of resistivity. Resistivity of conductors are poor while the resistivity of
attributable to these electrons. Metals are extremely good conductors of electricity and heat,and are not transparent to visible light:a polished metal surface has a lustrous appearance. Furthermore, metals are quite strong,yet deformable, which accounts for their extensive use in structural ...
resistivity is an important property ,it is often discussed as the dielectric property or strength.The dielectric strength is a specific measure of a material's electrical insulating qualities .Metals generally are considered considered conductors of electricity while ceramics and polymers are insulators ...
Biomarkers in biofluids are widely used for medical diagnosis, but their use is limited by accessibility. Here the authors present a stretchable wearable sensor allowing in situ detection of solid-state biomarkers on human skin, hence avoiding biofluid acquisition. Ruth Theresia Arwani , Sherwin Chong...
