中文摘要：
为了研究旋转抛物面薄透镜组的光心,首先讨论了单个抛物面薄透镜的光心,在此基础上,根据等效光学系统理论,对旋转抛物面薄透镜组的光心定义、性质和位置进行了详细的探讨和研究,发现旋转抛物面薄透镜组的光心位置取决于两抛物面薄透镜的间距、抛物面的形状、两透镜材料及其周围介质的折射率,最后讨论了空气中旋转抛物面薄透镜组在几种特殊情况下的光心位置.
英文摘要：
In order to study the optical center of the rotational parabolic thin lens combinations,the authors first discuss the optical center of a single parabolic thin lens,then based on the theory of equivalent optical systems,they study the definition,nature and location of the optical center of the rotational parabolic thin lens combinations in detail,and find that the location of the optical center depends on the lens spacing,parabolic shape,the lens materials and the refractive index of the surrounding medium.Finally they discuss the location of the optical center of the rotational paraboloid in some special circumstances in the air.
