They look out into the sky, into the stars, and see a slight variance in light rays that come over the vastness of space, and assume a straight path, or nearly straight.
他们抬头仰望，看向群星，发现从广阔的宇宙射来的光线变化轻微，并假定光沿直线传播，或这近乎直线。
As the density increases, the path of light rays emitted from the star are bent and eventually wrapped irrevocably around the star.
随着密度的增加，恒星里所发出的光线的路径会发生弯曲，并最终不可逆地围绕包裹着恒星。
This platform can simulate the ray tracing for a fixed frequency or sweeping frequencies, also can calculate the group path and the covered region of rays.
该平台可实现定频或扫频射线轨迹演示，计算各射线群路径，覆盖区域等功能。
