摘要
架状硅酸盐矿物晶体结构为氧离子作开层堆积,阳离子充填空隙而形成.矿物晶胞参数与硅氧四面体的排列方式有关,和硅氧四面体的棱长l、对棱间距T_(?)、四面体的高T_h等几何要素有确定的函数关系.
The crystal structure of the framework silicate mineral consists of the oxygen ionic as the opening cumulate and the cation as the filling povosity. The mineral unit cell parameter has something to do with the arrange pattern of the silicon-oxygen tetrahedron, and it has difinite function relationship with the geometrical key elements of the silicon-oxygen tetrahedron which includes the edge length l, the distance of opposite edges 7Y and the height Tk etc.
