Three aspects on solving queuing service system in Shanghai world expo

This paper analyzes the queuing problem that was experienced during the Shanghai World Expo of2010.The queuing problem will be discussed at three levels.The three levels include the physical,psychological,and social aspects of the queuing problem.The collective behavior of visitors is studied through analyzing the information from the different sources,such as,the network of electronic eyes,the evaluation platform based on mobile phone system and the Internet.A hybrid information network technology is implemented.Based on the Wuli-Shili-Renli(WSR) system methodology,a new theoretical analysis framework for the queuing problem is proposed.

Bathynotus: A key trilobite taxon for global stratigraphic boundary correlation between Cambrian Series 2 and Cambrian Series 3

The Cambrian trilobite Bathynotus is a special morphology of Redlichiid,which is characterized by a wider thorax axis and an 11th macropleural segment bearing a long,backwardly directed spine.Additionally,its 12th and 13th pleural segments are narrow and they terminate at a fulcrum where they fuse together and to the posterior edge of the long macropleural spine.The genus is widely distributed,occurring in North America,Siberia,the Altay-Sayan fold belt of Russia,South China,the Tarim Basin of China,and Australia.It occurs primarily in deposits of the upper part of the continental slope,at the transition between stable platform settings and subsiding margins of the late Early Cambrian.Here,we recognize three species of Bathynotus from China,including B.holopygus which is widespread around the world.Although six species of Bathynotus have been reported from Siberia and the Altay-Sayan fold belt area of Russia,data presented here suggest that only three of these species are valid.Bathynotus exhibits a short geological range,with its first occurrence late in the unnamed Cambrian Series 2 and the last appearance datum of Bathynotus at the boundary of Cambrian Series 2 and Cambrian Series 3.The late appearance datum (LAD) of Bathynotus provides an important global stratigraphic marker of the boundary between Cambrian Series 2 and Cambrian Series 3.     

微量元素硼对小麦生长发育及碳水化合物代谢的影响

春小麦赛洛斯用适宜浓度的认浸种和各期根外追肥的方法处理后，皆可促进小麦幼苗根系的生长发育；促进生长锥的分化和器官的形成过程；可提高主茎旗叶面积和花粉生活力；可促进小麦叶部和生殖器官糖类的合成和叶内由光合作用制造出的糖类向生殖器官的运转；春小麦赛洛斯用硼进行根外追肥的时期，从孕穗－开花期喷射效果最显；用硼进行播种前处理和根外喷射，皆能提高小麦产量。     

画坛独步说梁楷

梁楷以“减笔画”画法闻名于世,这种笔法不重笔墨铺陈,而重线条的灵转活泼,不重形似,而重神似,由此确立了他在画坛上的地位。     

乌鸡白凤口服液扶正固本作用的动物实验观察

目的 :观察乌鸡白凤口服液的益气养血功能 ,比较乌鸡白凤口服液与乌鸡白凤丸二种剂型的作用差异。方法 :观察药物对急性小白鼠血虚模型的影响及对小白鼠急性应激反应的影响。结果 :乌鸡白凤口服液能显著促进失血小鼠 RBC,Hb值的恢复 ,能显著提高小鼠的抗应激能力 ,延长小白鼠常压缺氧死亡时间及延长小白鼠游泳时间。乌鸡白凤丸也是具有相似的作用。结论 :乌鸡白凤口服液具有补气养血 ,升高血红蛋白 ,提高红细胞值的作用
