As long as this condition is satisfied a single light beam can be used to trap a particle in
the regime where the size of the particle is much less than the wavelength of light. This
is called the Rayleigh regime.
rayleigh是英國物理學家Lord Rayleigh的名字，通常譯為瑞利，在聲光波和電磁學等多個領域有所貢獻，提出rayleigh散射概念及理論是其主要成就之壹。請查閱有關資料。
regime在物理學中有區域，範圍，環境，條件等意思，壹般譯為區域。
瑞利散射：
Rayleigh scattering, named after the British physicist Lord Rayleigh, is the elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the light. The particles may be individual atoms or molecules. It can occur when light travels through transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering is a function of the electric polarizability of the particles.
瑞利散射（rayleigh scattering） ，以英國物理學家羅德瑞利名字命名，是比光波長更小的粒子的光或其它電磁輻射的彈性散射。這些粒子可能是單個原子或分子。它在光通過透明固體和液體傳播時產生，但以氣體中最為多見。瑞利散射是粒子的壹種電極化作用。
大氣中太陽光的瑞利散射造成天空漫輻射，它是天空顯現藍色的原因。
