Due to the special physical and chemical characteristics , nano materials was begun to used in the batteries , especially the secondary batteries 纳米材料具有特异的物理和化学性质，近年来开始在电池中得到应用。
On the one hand corals are not particularly sensitive , but with a hardness of only 3 . 5 they are much softer than any other gemstone material 珊瑚的化学性质不稳定且其摩氏硬度只为3 . 5 ，和其他宝石相比较是极软质的。
A great deal of attention has been paid to one - dimensional nanostructural materials due to their novel electrical , optical , magnetic and chemical properties 一维纳米材料具有一些新奇的电学、光学、磁学和化学性质。
Any change which alters the chemical properties of a substance is a chemical change . for example , the rusting of iron is a chemical reaction 任何改变物质化学性质的变化都是化学变化。例如，铁钉的生锈就是一种化学变化。
Having established these lists , they went to the library to find out what was known about the plants ' chemistry 名单确定之后，他们就到图书馆查询这些植物的化学性质，旨在找出每种植物所拥有的作用最为突出的“化学武器” 。
Chemical features aluminum silicate of cenospheres would not be changed while they are mixed with water , acid , alkali and other chemical materials ：漂珠可以添加在溶剂有机化学物质水酸或碱类中，而不会改变其化学性质。
Also the usage of proposed graphic models allows the visual graphic interpretations of a number of physical and chemical phenomena , especially chemical reactions 并且该法的应用可以解释许多的物理和化学性质，特别是化学反应性质。
Non - toxic to animals , plants and humans . - very environmentally friendly as they break down into natural soda ash andor borax after the oxygen is released 此外，过氧碳酸钠化学性质不稳定，遇水、重金属离子等易分解，其化学反应式如下：
Since its chemical character is very active , mg alloy is prone to oxidation and burning , which makes it impossible to be melted and cast in air 但由于镁的化学性质活泼，非常容易氧化、燃烧，导致镁合金无法在大气条件下直接进行熔炼和浇注。
Magnesium oxide as a bonding , provide a unique chemical character with only little temperature occurred during grinding , can reduce the deformation of work piece 以氧化镁为结合剂，因具有独特化学性质研磨时发热极少，可降低研磨时工作物变形。
