In order to maintain electrical neutrality , some trivalent b ions oxidized to form b4 + , which resulted in a net decrease in the average radius of the b ions , as a result the volume of the unit cell decreases
为保持电中性，一些三价的b离子氧化变成四价的b离子，这一变化导致b位离子平均半径的减小，从而导致晶胞的整体减小。
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。
Locally , the incidence of meningococcal infections is low and about half of the meningococcal infections were caused by neisseria meningitidis serogroup b . the quadrivalent meningococcal vaccine does not confer protection against meningococcal infections caused by serogroup b , its duration of protection is short and it is relatively ineffective in children aged under 2
本港每年的脑膜炎双球菌感染病例中，约一半为b型的双球菌所引致。由于脑膜炎双球菌感染在本港并不常见，加上四价疫苗对b型的双球菌没有效用有效期间较短及对两岁以下儿童的效果较低，故此疫苗并不在本港免疫注射计划采用之列。
According to the sample prepared by hydrothermal method , the doping cations can enter the spinel lattice . rare earth cations mostly occupy position b because of their big radius . cerium are oxidized to ce4 + , whose radius is relatively small , and ce4 + mostly occupies position a . as a whole , the coercivity of cobalt ferrite doped with rare earth element is bigger than that of pure cobalt ferrite
结果表明，对水热法制备的铁氧体粒子，杂质离子能够进入其尖晶石晶格中，并因稀土离子的半径较大，而绝大部分占据尖晶石的b位，铈元素因被氧化成为四价离子，离子半径相对较小，而主要占据a位。
