The intensity of scattering I(theta) by transparent and absorbing spheres has been calculated from exact Mie theory for values of radius from 0.1 microm to 100 ,microm, wavelength 5461 A, and the following values of refractive index m - im': (1) m = 1.01, 1.05, 1.1 (0.1) 2.0, m' = 0; (2) m = 2, m' = 0.002, 0.02, 0.2, and 2. The calculations have been made for a range of scattering angle theta large enough to indicate the first maximum in I(theta)theta(2). According to the Sloan method for determining particle radius, the location of this maximum is inversely proportional to radius, independent of refractive index. The exact calculations show that this is accurate for radii above 10 microm, but for smaller particles the value of the refractive index affects the location to some extent.
对于半径从0.1微米到100微米、波长为5461埃以及以下折射率m - im'值的透明和吸收球体，已根据精确的米氏理论计算了散射强度I(θ)：(1) m = 1.01、1.05、1.1（步长0.1）到2.0，m' = 0；(2) m = 2，m' = 0.002、0.02、0.2和2。已针对一系列散射角θ进行了计算，该散射角范围足够大，以表明I(θ)θ(2)中的第一个最大值。根据斯隆确定颗粒半径的方法，该最大值的位置与半径成反比，与折射率无关。精确计算表明，对于半径大于10微米的情况这是准确的，但对于较小的颗粒，折射率的值会在一定程度上影响该位置。
