In Chapter 2, the refractive index distribution and raytrajectory of GRIN ball lens are studied in theory.
第二章主要从理论方面研究梯度折射率球透镜的折射率和光线轨迹。

It is shown that the raytrajectory depends strongly on the spot size and the inclination of the incident beam and the structure of the lens.
计算结果表明，光线轨迹主要由入射光束的光斑尺寸、倾角和透镜的结构决定。

Because cosmic rays are charged, their inbound trajectory should be jumbled by the Milky Way's magnetic field, so any hot spot on the cosmic ray map demands an explanation.
