摘要
随着烟火学研究的进步,烟火器材的发展也进入了新的领域,烟火电流发生器是一种将烟火装置的化学能转变为电能的新型烟火器材。本文介绍了装药为碳化锆和硝酸钠的带有铜轴向电极的烟火电流发生器放电性能实验,测试了输出电压随时间的变化情况。通过对实验现象和所记录数据的分析,得到了药柱直径、氧化剂硝酸钠含量等因素对烟火电流发生器放电性能的影响规律。从理论上阐述了烟火药剂燃烧产生电效应的电化学理论基础,在此基础上对烟火药剂燃烧时产生电效应的机制进行了初步的分析。烟火电流发生器电动势值为累积大小,其形成过程是燃烧的烟火装药冷却阶段不同区域的各个电流形成过程的累加,烟火药剂燃烧产生电动势的规律符合熔盐电化学原理。
An intelligent bus dispatching system can better meet people's travel needs. The optimized algorithm takes advantage of advanced technology and equipments. However, in recent years the development of Chinese intelligent bus dispatching systems is not satisfactory with an. excessive attention to advanced technology but less to practicality. Dynamic scheduling has yet to be fully exploited. In this paper, intelligent transportation scheduling systems and scheduling characteristics are analyzed. The information about dynamic transportation and vehicle locations is acquired and merged. An optimization model for intelligent dispatching of buses is proposed on basis of real data. This model is under the support of GPS positioning, communications, computers and other technologies, where intelligent algorithms are used in busoperation and dispatching and both passengers satisfaction and company profit are considered. The method of collecting data automatically and the algorithm of this model are presented. This model is shown to be able to significantly improve the rate of bus full loading, shorten the waiting time of passengers, and reduce the total vehicle trips, with an evident effect of optimized dispatching.
