Optimization Scheme of Large Passenger Flow in Huoying Station,Line 13 of Beijing Subway System

This paper focuses on the distribution of passenger flow in Huoying Station,Line 13 of Beijing subway system.The transformation measures taken by Line 13 since operation are firstly summarized.Then the authors elaborate the facilities and equipment of this station,especially the node layout and passenger flow field.An optimization scheme is proposed to rapidly distribute the passenger flow in Huoying Station by adjusting the operation time of the escalator in the direction of Xizhimen.The authors adopt Queuing theory and Anylogic simulation software to simulate the original and the optimized schemes of Huoying Station to distribute the passenger flow.The results of the simulation indicate that the optimized scheme could effectively alleviate the traffic congestion in the hall of Huoying Station,and the pedestrian density in other places of the hall is lowered;passengers could move freely in the hall and no new congestion points would form.The rationality of the scheme is thus proved.

云南澄江早寒武世地层并论中国的Parabadiella,摩洛哥的Abadiella及澳大利亚的Abadiella huoi(英文)

根据近来的发现 ,区域地层的阐明及生物在寒武系与前寒武系界线上下的变化 ,澄江早寒武世地层划分作了修订。早寒武世岩石地层名称的更换 ,年代地层及生物地层单位的分带这里作了简述。目前的岩石地层单位从下到上是渔户村组 (梅树阶 ) ,黑林铺组 (筇竹寺阶 ) ,红井哨组、乌龙箐组 (沧浪铺阶 )及山邑村组 (龙王庙阶 )。此层序可分为 12个组合带及 2个亚带。所有的组合带在中国西南地台区都有存在 ,但两个亚带在澄江是区域性的。云南东部震旦系与寒武系的界线暂时置于渔户村组小歪头山段的底界 ,位于小壳化石最早出现的下部。中国的Parabadiella ,摩洛哥的Abadiella及澳大利亚的Abadiellahuoi这里重新作了研究。Parabadiella及Abadiella是两个不同的属。模式标本的图片在这里再次刊出。澳大利亚的Abadiellahuoi一种应是Wutingaspis的一个新种 (WutingaspisjelliChangsp .nov .)。¨Opik( 1975 )的Dolerolenus( ?)sp .nov .一种应归属Parabadiellahuoi一种。Parabadiella是中国也是澳大利亚寒武系最古老的三叶虫。澳大利亚的Wutingaspisjelli的层位与摩洛哥Abadiella的层位相当 ,可与中国的Wutingaspis Eoredlichia带的上部对比。
