Using combinatorial thoughts and topological methods,a closed curve system that contains the most number of non-contractible,pair-wise disjoint and pair-wise non-homotopic closed curves on the orientable surface is investigated.

利用组合数学的思想、拓扑的方法研究在可定向曲面上，一类含有个数最多的不可收缩的、两两不相交、互不同伦的圈系统及其性质，得出了关于这些圈的一些拓扑定性性质，并给出这些圈在曲面上的位置分布。

Through studying the intersection of paraboloid of revolution and cylinder , the author concluded that the horizontal projection of the intersecting lines—, is the famous Four-order algebra curve-Perseus curve.

通过对回转抛物面与圆柱面相交的研究，得出交线的水平投影曲线——为四次代数曲线——Perseus座曲线的结论。

The karst caves could be accurately detected only when the boundary of the karst caves has a horizontal extension, as well as the interface of the karst caves is single plane and the normal direction is parallel or small angle intersection (0°~45°) with tunnel axis.

只有溶洞的边界有一定的横向延伸性，溶洞界面呈非常明显的单一平面特征，其法线方向与隧道轴线平行或以较小的角度相交(0°~45°)，溶洞才能被准确探测。

An interference pattern of two systems of fringes has been obtained by vising two radiations in a Hilger prism interferometer A system of white bands with equal spacing which are always parallel to the refracting, edge of the prisin is the result of the intersection of the two systems of fringes.

在Hilger棱镜干涉仪中，用两辐射线，则在一干涉图形中可得两组不同方向之干涉纹；因两组不同方向之干涉纹之相交，而得一组平行之白色条纹。此种条纹恒与棱镜折射边相平行，而条纹间之间隔为相等。
