In chapter 3 we obtain a new upper bound for " k - l problem " concerning line transversal to unit disks in the plane, where we prove that for a finite disjoint family f of unit disks in the plane, there is a line intersecting all but at most 5 members of f suppose that even " three of the members admit a line transversal. thus we improve the latest upper bound 12
在第3章中我們討論了直線橫截的有關問題，給出了單位圓「 k l 」問題的一個新上界，即證明了對于平面上有限個兩兩不交的單位圓形成的集族，若其中任三個單位圓可被一直線橫截，則存在一條直線至多不與此集族中的5個單位圓相交，從而改進了原有上界12 -
A geometric transversal is defined to be an affine subspace ( such as a point, a line, a plane, or a hyperplane ) intersecting every member of a given family. in part i we discuss three kinds of such problems. in chapter 2 we discuss point transversal to a family of translates of a convex sets in the plane, where we prove a famous conjecture of griinbaum ' s by a concrete and straightforward method for some special cases
如果一仿射子空間（如一個點，一條直線，一個平面，或一個超平面）與一給定集族的每一個元都相交，則我們稱該仿射子空間為該給定集族的一個幾何橫截（點橫截，直線橫截，平面橫截等） ，也稱該仿射子空間橫截該給定集族。
