【Abstract】 Based on the theory of geometrical optics,the relationship between the axial force exerted on the micro-sphere particles in the Mie scattering field and the main parameters of laser is calculated quantitatively when the absorption is considered.the results not only show the relationship between the axial force and some parameters,that include the absorption coefficient of microscopic particles,the laser wave-length,power and so on,but also are useful for choosing parameters in experiments.更多还原
