| 摘 要： | 二次曲面的反射系统只有一对理想共轭点，在傍轴条件下，有一对准共轭区。各种形状的反射面的准共轭区的特点(位置、范围)是不同的。准共轭区的中心位置及范围都与反射面的理想共轭点位置有关，由反射面的几何因素决定。同时，准共轭区的范围与反射面的纵向放大率规律密切相关。准确把握准共轭区具有重要的实践意义。

| Abstract: | Quadric reflectors have only one pair ideal conjugate pointses, and axial mirror have a pair of approximately conjugate area . The conjugate characteristics( position, scope) of every kind of reflectors is different .The center position and scope of the conjugate area are all concered with the position of ideal conjugate point, all regulated by the geometric equation reflectors. And the scope of the conjugate area is concered nearly with the general rules of longitudinal magnifying power of reflectors. It is very important to grasp the rules of approximately conjugate area accurately in practices. |
