By the comparison between archaeological stratigraphy, sediment characteristics of cultural layers and cultural interruptions, 46 ~(14)C chronological data of buried paleotrees and peat, the synthetical analysis of the distribution laws of sites, and the reference to the results from other scholars, we can see that there are 7 cultural interruptions in the three Gorges and 7 cultural interruptions in the Yangtze Delta. They are from the last stage of Chengbeixi Culture to the initial stage of Daxi Culture (7200~6000a BP)→the third stage of Guanmiaoshan Culture Style of Daxi Culture (5800~5500a BP)→the initial stage of Shangzhou Culture (4000~3500a BP )→the last stage of Shangzhou Culture (2500~2200a BP)→During the Song dynasty Culture (960-1276AD) During the Ming and Qing Culture (1368-1911AD) in the prehistorical and historical period in the three Gorges.
对长江三峡和长江三角洲考古遗址进行地层对比,考古遗址文化层和文化断层沉积特征、文化层的叠压关系、考古遗址淤砂和淤土层厚度、46处埋藏古树和39处泥炭的~(14)C年代统计数据和空间分布规律、文化遗址分布的时空变化规律等特征综合分析,发现长江三峡地区新石器时代到历史时期考古遗址地层中有7期文化断层:(1)城背溪文化末期到大溪文化初期(7200~6000a BP);(2)大溪文化关庙山类型三期(5800~5500a BP);(3)商周早期(4000~3500a BP);(4)商周晚期(2500~2200a BP);(5)宋代时期(960-1276AD):(6)明清时期(1368-1911AD);(7)近现代时期。

The invention relates to a dynamic matrix control system of high-purity distillation, which comprises distillation tower, intelligent checker, DCS system, superior host, and on-site bus, while they are connected. The control system uses tower product group as the object variable, and the reflux ratio and reboil ratio as control variable; the superior receives history temperature and pressure data from the DCS real-time database, via the predict control and dynamic matrix controller, to obtain the output values of present controller as reflux ratio and reboil ratio, then feedback said two values to DCS system, to function the distillation object. The invention can confirm the high-purity stable operation, with better dynamical control.
本发明公开了一种高纯精馏的动态矩阵控制系统和方法;系统包括:精馏塔、智能检测仪表、DCS系统、上位机和现场总线;所述精馏塔、智能检测仪表、DCS系统和上位机通过现场总线依次相连,实现信息流的上传和下达;本发明所涉及的控制系统采用塔双端产品组分为被控变量,回流比和再沸比为对应的控制变量;上位机从DCS实时数据库中获得历史的温度、压力等数据,通过推断控制环节和动态矩阵控制器环节,得到当前控制器的输出值-回流比和再沸比,再把控制器输出值返回给DCS系统,实现了对高纯精馏过程的双端产品高纯控制,对双端组分的高纯度平稳操作,具有很好的动态品质和控制效果。
