交通建模中的最短路径算法分析与测试
Journal Title: Science Paper Online - Year 2009, Vol 4, Issue 10
Abstract
交通建模一直以来就是最短路径算法极为重要的应用领域。介绍主流的最短路径算法——标号算法,通过交通网络特征分析和实际城市道路网络中的算法测试,给出如何选择适合交通网络的一般最短路径算法的建议。分析交通建模中各类特殊最短路径算法的研究需求,包括带转向约束的算法,带时窗约束的算法,动态、随机、自适应算法,k-最短路径算法,启发式搜索算法,再优化算法等。最后对未来研究趋势作出展望。

钴基催化剂费托合成动力学模型
由于钴基催化剂的活性组分为Co,反应中CO2的生成量很少,水煤气变换反应可不予考虑,所以钴基催化剂上烃的生成为主要反应。在费托合成碳化物机理的基础上,建立了烃生成的可能基元反应,以生成碳化物的基元反应为控制步骤,推导出8个钴基...
