本文给出了大尺寸球形介质散射体电磁共振尺寸参数x（n）（（l））的高阶渐近展开式。展开计算到阶数n（-8/3），其中n是模数，并且对于小阶数l有效。它的准确性研究作为一个函数的n，l，和折射率。对于l = 1模式，当n > 50时，相对精度优于10（-4）。
A high-order asymptotic expansion for the size parameters x(n)((l)) of electromagnetic resonances of large spherical dielectric scatterers is reported. The expansion is calculated up to order n(-8/3), where n is the mode number and is valid for small orders l. Its accuracy is studied as a function of n, l, and the refractive index. For the l = 1 mode, the relative accuracy is better than 10(-4) for n > 50.
