The novel does not provide the faithful historical drawings of a certain period or the analytic critiques of its social structure.───小说既不提供某一时代的忠实的历史画卷,也不提供对其社会结构的分析批评。 英语使用场景 Endill made drawings of his plane in his diary and on large pieces of pape...
In an orthogonal drawing of a plane graph G each vertex is drawn as a point and each edge is drawn as a sequence of vertical and horizontal line segments. A point at which the drawing of an edge changes its direction is called a bend. Every plane graph of the maximum degree at most ...
A straight-line grid drawing of a plane graph G is a planar drawing of G, where each vertex is drawn at a grid point of an integer grid and each edge is drawn as a straight-line segment. The height, width and area of such a drawing are respectively the height, width and area of ...
Fig. 1 shows an example of a plane graph G, an orthogonal drawing of it and a bend-optimal orthogonal drawing of it. Due to the way they are used in circuit schematics, orthogonal drawings with minimum number of bends are particularly desirable. It is clear from the definition of an ...

Figure 1.6shows the three non-isomorphic good drawings of K_4 in the plane. The second and third are isomorphic if we work in the sphere.A drawing in the plane is a drawing in the sphere with a designated outer (unbounded) region; drawings in the plane are easier to visualize, but dra...
Definition 3.1. A good drawingD(G)of a graphGis a drawing of the graph where each vertex is represented by a distinct point in the plane (or equivalently on the sphere) and edges are drawn as simple arcs connecting the corresponding endpoints (vertices). Additionally,no arc is allowed to ...

It will find a space in the model space and invoke the Lay program to lay out the parts with the main plane flat in the XY plane. Will write, if necessary, a heading for each part with a description of the material and quantity. Insert sheets (layouts) from the template and target ...
