求英文好的帮忙翻译一下毕业论文的摘要，万分感谢！！！
光从右向左时的成像规律的探讨摘要:透镜成像原理是一项广泛而复杂的理论，本文旨在前人研究的基础上，根据对光从左向右传播时单球面及薄透镜的成像规律的学习和研究，推导出了光从右向左入射情形下单球面及薄透镜的成像规律，对两种情况下单球面的反射、折射，以及薄凸透镜折射的成像规律进行了对比，得出了光分别从两种方向入射时，几种光学器件成像规律的相同与不同之处。并且给出了作图求像法等几何光学的重要内容。关键词：符号法则；单球面；薄透镜

Light from right to left to explore the imaging when abstract: the principle of lens imaging is a broad and complex theory, the purpose of this paper is to, on the basis of previous studies, according to the light travels from left to right in the spherical and thin lens imaging study and research of their law, deduced the incidence situation order spherical light from right to left and thin lens imaging, to place the order with two cases of spherical reflection, refraction, and compares the thin convex lens refraction law of imaging, the light is obtained respectively from two direction incidence, several optics imaging rule with the same difference. And gives the mapping for the important content of geometrical optics, such as method.
