石油焦与煤混合燃烧是高效处理石油焦的有效方法,作者对选用的石油焦和煤不同配比的混合燃料进行了热重分析研究。使用常压高温热天平研究、分析了各配比混合燃料的热解特性和燃烧特性。并根据化学动力学方法计算了各过程的化学动力学参数,即活化能E和频率因子A0。结果表明,各混合燃料热解起始温度大致相同,随煤焦比减小,挥发分析出速率变缓,最大释放速度所对应的温度升高,最终失重率减小,挥发分释放特性指数减小;随煤焦比增大,混合燃料着火温度和燃尽温度逐渐降低,最大燃烧速率所对应的温度降低,燃烧特性指数增大;随煤焦比减小,活化能和频率因子增大。

中成药的生产受原料(中药材)价格和资源存量的影响比较大,一方面,原料药材价格呈现周期性剧烈波动甚至是不可逆的飙升,使得中成药价格不稳定甚至出现成本与最高零售限价倒挂,另一方面,因资源不足或者禁用导致部分中成药被迫停产。中成药国家基本药物保障监测分析系统基于微服务架构,应用Redis实现了系统的集群部署,围绕《国家基本药物目录》(201.年版)中的203种中成药,通过连接和整合中药资源普查数据库、中药资源动态监测数据库、中成药国家基本药物数据库数据,实现了中药材及中成药的动态监测和预警智能化。
