平面图

In Chapter 2,we prove that:(1)each planar graph without {4,6,7,9}-cycles is 3-colorable;(2)each planar graph without {4,6,8}-cycles is 3-colorable.

在第二章中，我们证明了以下两个结果：(1)每个不包含{4，6，7，9}-圈的平面图是3-可染色的；(2)每个不包含{4，6，8}-圈的平面图是3-可染色的。

In Chapter 2, we show that Xi 3 for all planar graphs of girth not less than 4 which contains no 5- and 6-circuits or contains no 7- and 8-circuits or contains no 8- and 9-circuits, we also show that Xi 3 for each planar graph of girth not less than 4 which contains no 6-, 7- and 9-circuits.

在第二章，论文证明了每个围长至少为4且不含5-圈和6-圈或7-圈和8-圈或8-圈和9-圈的平面图是3-可选色的。同时还证明了每个围长至少为4且不含6-圈，7-圈和9-圈的平面图是3-可选色的。

In Chapter 3,we obtain that:(1)each planar graph without 4-cycles is acyclically 6-choosable;(2)each planar graph without 4-cycles and without triangles at dis-tance less than 3 is acyclically 5-choosable.

在第三章中，我们获得了以下两个结果：(1)每个不包含4-圈的平面图是无圈6-可选择的；(2)每个不包含4-圈并且任意两个三角形之间的距离至少是3的平面图是无圈5-可选择的。

Used the way of discharging to prove that every planar graph without 4-cycles and i-cycles for some i ∈{5,6,7} is (3, l)*-choosable, when they studied the list improper colorings of plane graphs.

72在研究平面图的列表非正常染色时，结合欧拉公式用放电的方法证明了每个不含4-圈和i-圈的平面图是(3，1)~*-可选的，其中i∈{5，6，7}。

In section four,we will study the star-edge coloring of maximal outer plane graph and maximal plane graph,and bound their star chromatic index.

第四节研究了极大外平面图和极大平面图的星边染色，并界定了它们的星边色数。

We also get another expression of Steinberg's conjecture about plane graphs, that is, every plane graph without i(4≤i≤5) faces in which any two triangles have distance at least 3 and no 3-face is adjacent to any 6-faces is 3-colorable.

我们还得到平面图的一个类似结论：没有4、5面的平面图中如果任意两个3圈的距离至少为3，而且没有3面和6面相邻，那么这个图也是可以3色的。

We also get another expression of Steinbergs conjecture about plane graphs, that is, every plane graph without i(4≤i≤5) faces in which any two triangles have distance at least 3 and no 3-face is adjacent to any 6-faces is 3-colorable.

我们还得到平面图的一个类似结论：没有4、5面的平面图中如果任意两个3圈的距离至少为3，而且没有3面和6面相邻，那么这个图也是可以3色的。

Herein we give the transfer rule for an equivalent circuit including Warburg impedance as follows: for ...

应用此规则，可以将在一个复数平面图上的研究结果直接用到另一个复数平面图上，因此，变换规则是一种颇为有用的电化学交流阻抗研究的手段。

We apply the results in Chapter 2 to the equitable list coloring of graphs and prove that a graph G is equitably △-choosable if G is a plane graph without i-cycles, 3 ≤ i ≤ 5, or a plane graph without 4-cycles(or 5-cycles) and 6-cycles.

从而得出不含3-圈，4-圈和5-圈的平面图和不含4-圈(或5-圈)和6-圈的平面图GΔ(G≥6均有一个Δ-均匀列表染色。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.

是的。事实上我是我们市队的。
