化学价 meaning in English

valence.pro

With doped ni element , the material converted into n - type semiconductor , what ' s more it has very low seebeck coefficient which shows ni is + 4 in this material
掺入一定量的ni后，转变为n型半导体材料，它的seebeck系数非常小，表明ni在这个化合物中的表观化学价的+ 4价。
The ability of carbon to form stable compounds in such astonnishing numbers arises in that it utilizes its four valence electrons completely in the establishment of four covalence , its valence shell becomes saturzted
试译一下：碳能组成（有着）如此惊人数量的稳定的化合物在于它在四价共价健的建立中充分利用自己的四价电子，它的化学价层才能得以饱和。
With the development of nulear power industry , more and more attention has been given to the spent nulear fuel reprocessing . purex process will remain predominant in the foreseenable future . because the valence of np , one kind of transuranium elements , is easy to interchange , the route of np in purex process is difficult to be controled . a lot of work has been done on the control of neptunium way in the world
随着核电的发展，乏燃料后处理引起了人们的广泛关注。 purex流程在乏燃料后处理中一直占有主导地位。由于超铀元素np的化学价态容易相互转变，使purex流程中np的走向不易控制而倾于分散。
