Three intersection functions,such as adjacent node set,node-arc angle set and connected node set,were presented,and based on the shortest path method proposed by Dijkstra,a road guide sign model was built by using the intersection functions.

结合路网的拓扑结构，定义了用于确定指路标志的状态函数集，给出了3个描述路网拓扑特征的交叉口函数：邻近结点集、结点-弧段夹角集和连通结点集，基于Dijkstra最短路径的思想，运用交叉口函数建立了城镇指路标志的标识模型：以待标识城镇为中心，在城镇的影响区域内，通过向外搜索交叉口邻近结点集来确定指路标志的设置，并使每个结点上标识的路径都是最优的。

The "Prufer" code of such a tree is built as follows: the leaf (a vertex that is incident to only one edge) with the minimal number is taken. This leaf, together with its incident edge is removed from the graph, while the number of the vertex that was adjacent to the leaf is written down.

从题目描述我们可以知道，对于一棵树，每次都找到编号最小的叶子结点，然后输出它的双亲结点的编号作为 Prufer Code，同时删除这个最小的叶子结点为下一次输出 Prufer Code 做准备。

We will meet them again and again in the course of this year, which began on the First Sunday in Advent, for this is the year in which it is mostly parts of the Gospel of Luke that are read.

以路加福音为主轴的丙年已经从将临期第一主日开始，我们将在这个礼仪年里不断地领略路加的细腻描述。

Two-equation turbulence model is used in numerical simulation for the side-air burner, compared with the practical measures and tests, good accordance achives. This method can bring great convenience in analyzing aerodynamical field of boiler. Secondly the method of XRD is used in analyzing the phase transformation in the course of dynamic slagging test, so we can describe the process of slagging comparatively accurately. Last this paper introduces a kind of fuzzy mathematics model which comprises an assemblage combined by seven change factor.

本文首先采用k—ε双方程模型对水煤浆侧边风燃烧器进行了数值模拟，并与实际锅炉燃烧器冷态调试试验结果对比，结果吻合较好，这为我们分析炉内空气动力场特性提供了参考；其次对锅炉结渣动态特性试验，采用XRD的分析方法，较为准确的描述了实际锅炉结渣的过程；最后为了准确的判断出水煤浆的结渣倾向，本文对锅炉结渣的七个影响因素提出了模糊综合判断模型，正确的反映出了该水煤浆的结渣倾向。

Firstly the k-e two-equation turbulence model is used in numerical simulation of the flow field ,compared with the practical measures and tests, good accordance achives. This method can bring great convenience in analyzing aerodynamical field of boiler. Secondly the method of ash-composition, ash-melting-point, XRD is used in analyzing the phase transformation in the course of dynamic slagging test, so we can describe the process of slagging comparatively accurately. Last this paper introduces a kind of fuzzy mathematics model which comprises an assemblage combined by seven change factor.

接着采用标准k—ε双方程模型对炉内冷态空气动力场进行了数值模拟，并与实际锅炉燃烧器冷态调试试验结果对比，结果吻合较好，这为我们分析炉内流场提供了参考；其次对锅炉静态、动态特性试验，采用灰成分分析、灰熔点测试及X光衍射物相分析方法，较为准确的描述了实际锅炉结渣过程；为了准确的判断出水煤浆的结渣倾向，本文对锅炉结渣的七个影响因素提出了模糊综合判断模型，正确的反映出了该水煤浆的结渣倾向。

AS The Economist went to press this week, physicists were aflutter about an expected announcement from one of the world's most important experiments searching for dark matter—the as-yet-undetected material that, if models of the universe are correct, is about six times as abundant as the familiar, visible stuff.

本周《经济学人》发刊之际，物理学界正在为一个预期的发布会兴奋雀跃着。届时，将宣布世界上一个最重要的实验的结果：寻找暗物质——一种尚未发现的物质。如果宇宙真如宇宙模型的描述般，宇宙中暗物质的含量将是人们熟悉的可见物质的6倍之多。

Secondly, on the base of Jarrow's(1997) credit rating mitigation matrices estimating approach, this dissertation focuses on the macro economic's influntion and assumes credit rating mitigation is Non-homogeneous Markov Chain conditional on macro economic risk factors.

最后以Duffie和Singleton(1999)的基于违约强度的市值回收公司债券定价模型为基础，在信用评级迁移为条件Markov链的假设下，使用带跳跃的均值回复过程描述信用评级迁移事件，建立公司债券定价模型，进而利用带跳跃均值回复过程的良好性质解决风险中性期望问题，求得公司债券价格的显式解，得到每一信用评级公司债券的信用价差。
