稀土离子的晶体半径、4f电子数和配位数之间存在一定的关系。在此基础上，提出了由已知三价稀土离子晶体半径计算未知稀土离子晶体半径的两个经验公式。计算了不同配位数（N= 6-12）的三价和二价稀土离子的晶体半径和有效离子半径。计算结果令人满意，大多数算例的相对误差小于1.0%。
There exist some relationships between the crystal radii of the rare earth ions, the 4felectron number, and the coordination number. On the basis of these relationships, two empirical formulas have been proposed to calculate the unknown crystal radii of the rare earth ions from the known crystal radii of the trivalent rare earth ions. The crystal radii and effective ionic radii of all the rare earth ions (trivalent and divalent) with different coordination number (N= 6–12) have been evaluated. The calculated results are very satisfactory, and for most of examples the relative error is less than 1.0%.
