1) quadratic cylinder
二次柱面
1.
Using the coefficient determinant and translation transformations,we discuss the positional relationship between a quadratic cylinder and a plane,which is involved the invariant of the quadratic surface and the invariants of the section of the quadratic surface,starting with discussing the positional relationship between a conic and a line.
利用系数行列式和平移变换,从二次曲线与直线的位置关系入手,借助二次曲面的不变量和二次曲面的截口不变量,由二次柱面的系数与平面的系数组成的行列式判定二次柱面与平面的关系。
2) conic-cylindrical reflector
二次曲线柱面
1.
Based on the ray tracing of cylindrical reflector,a three circularly cylindrical reflectors and a three conic-cylindrical reflectors system have been designed.
对柱面光线追迹及单片柱面镜成像进行了深入分析,分别设计了三反射式圆柱面和二次曲线柱面系统,提出了一种基于抛物柱面镜理想线聚焦的新型像差优化方法,使其在子午面方向各视场调制传递函数得到最佳优化,并达到成像光谱仪等在狭缝方向上高空间分辨率要求。
3) odd power cylimder
奇次柱面
4) prop twice
