face length造句

• Different facing lengths have different response properties.
• Variations include face angle, face length, back angle, gullet width and depth, and a frost notch ( if necessary ).
• In 2-connected planar graphs that are not maximal, there exist simple cycle separators with size proportional to the Euclidean norm of the vector of face lengths that can be found in near-linear time.
• We give the charge 6-d ( v ) to each vertex v and the charge 6-2d ( f ) to each face f, where d ( x ) denotes the degree of a vertex and the length of a face . ( Since the graph is a triangulation, the charge on each face is 0 . ) Recall that the sum of all the degrees in the graph is equal to twice the number of edges; similarly, the sum of all the face lengths equals twice the number of edges.
