The radiation force calculated in the Rayleigh regime is investigated by comparison with the generalized Lorenz Mie Theory (GLMT). The basic concepts behind the Rayleigh regime and GLMT are introduced, and a numerical simulation is conducted to analyze the difference between these two methods. Several physical parameters are considered to evaluate their effect on the calculation accuracy of the Rayleigh regime, including the particle size, optical wavelength, and beam waist. The numerical results show that the valid region of the Rayleigh regime depends primarily on the ratio of the wavelength and particle size, whereas the Gaussian beam size has a lesser impact on the calculation results for both methods. Our study provides critical conditions under which the Rayleigh regime is applicable. The calculation accuracy of the Rayleigh regime is also theoretically analyzed.

通过与广义洛伦兹米氏理论（GLMT）进行比较，研究了在瑞利状态下计算出的辐射力。介绍了瑞利体制和GLMT背后的基本概念，并进行了数值模拟以分析这两种方法之间的差异。考虑了几个物理参数以评估它们对瑞利格式的计算精度的影响，包括粒径，光波长和束腰。数值结果表明，瑞利格式的有效区域主要取决于波长与粒径的比值，而高斯光束的尺寸对两种方法的计算结果的影响较小。我们的研究提供了瑞利政权适用的关键条件。
