Comparison of the focusing results of a hot atomic beam with a monochromatic cold atomic beam shows that the main factor affecting the imaging quality of the magnetic lens is chromatic aberration.

在比较了热原子束和单色冷原子束的会聚效果后得出结论：影响它成像的主要因素是色差。

Under conditions of monochromatic light and a small object, the spherical aberration was the main factor which led to measuring error of focus of thin convex lens.

在单色光、小物条件下，球差是引起薄凸透镜焦距的测量误差的主要因素。
