回顾了行星天文学中反照率的各种定义。特别是Bond反照率，它只指反射和折射分量，不适用于小颗粒或高度不规则的颗粒，在这些颗粒中，衍射并不局限于在小散射角下的一个定义良好的瓣。不规则粒子的测量散射函数以归一化形式呈现，并应用于黄道光的情况。
The various definitions of albedo used in planetary astronomy are reviewed. In particular, the Bond albedo, which refers only to the reflected and refracted components, is not applicable to small particles or highly irregular particles, where diffraction is not restricted to a well-defined lobe at small scattering angles. Measured scattering functions for irregular particles are presented in a normalized form and are applied to the case of zodiacal light.
