表示分子或晶体中离子性(?)％,常用的方法是由键合原子上的有效电荷被价数除。Barinskii等人已经用X-射线发射光谱K_a线位移测定了硅酸盐中硅原子的有效电荷值为1.42—1.25,由这些数值得到Si—O键的(?)％为35.5％—31.3％。
Said molecular or crystal ionic (?)%, The common method is to bond the effective charge on the atom is divided by valence. Barinskii et al. Have determined the effective charge of silicon atoms in silicates from 1.42 to 1.25 by X-ray emission K_a line displacement, from which the (?)% Of Si-O bonds are 35.5% to 31.3%.
