求翻译：因为高斯光束发散角和束腰半径大致呈正比关系，所以采用理论分析和Matlab模拟的方法对高斯光束通过透镜传播进行研究。是什么意思？

Gaussian beam divergence angle and beam waist radius is roughly proportional to the relationship between theoretical analysis and Matlab simulation on the Gaussian beam for propagation through a lens.

Because Gaussian beam divergence and waist RADIUS generally has a positive relationship with the theoretical analysis and simulation methods to Matlab Gaussian beam propagation through lens.

Because the Gauss light beam divergence angle and the beam radius present approximately compare the relations, therefore uses the theoretical analysis and the Matlab simulation method conducts the research to the Gauss light beam through the lens dissemination.

Because Gaussian beam divergence angle and the radius of the beam waist roughly proportional relationship, theoretical analysis and Matlab simulation method study on propagation of Gaussian beams through a lens.
