英文摘要：

The axial optical force exerted on the Mie micro-sphere particles is calculated quantitatively based on the theory of geometrical optics. According to the calculation results, the relationship between the axial force and some parameters, including laser wave-length, beam waist, laser power, radius of the particle, refractive index and so on, are discussed.
