Then the Hadley circulation in the Eastern Hemisphere is weakened and that in the Western Hemisphere is enhanced, followed with the moment of momentum taken by its ascending branch increased in the Western Hemisphere while weakened in the Eastern Hemisphere. The PNA pattern is enhanced and the Pacific-East Asian teleconnection is weakened. As a result, the atmospheric circulation's response to the ENSO events in the Eastern Hemisphere is weakened and that in the Western Hemisphere is enhanced.
o事件使Walker环流减弱及其上升支东移的现象更明显,Hadley环流在东半球减弱而在西半球增强,由其上升支带至中纬的角动量在东半球减少,西半球增多,造成影响西半球大气环流的PNA型遥相关增强,影响东半球的太平洋-东亚型遥相关减弱,进而使得ENSO对东半球大气环流的影响减弱而对西半球大气环流的影响则有所增强。

1、Neural network correlated with LIFG and RIFG exists in normal subjects in resting-state,which might be the neural foundation in retaining the normal language function;2、The left fusiform gyrus,bilateral medial frontal gyrus and right anterior cingulum in aphasia patients after stroke showed low degree correlation,that might be one of the mechanisms of aphasia;3、The brain regions showed positive correlation with RIFG in aphasia patients only exist in right hemisphere in resting-state as well as which exist in bilateral hemisphere in normal subjects,suggested that RIFG is out of correlation with the left hemisphere in aphasia patients;4、The left thalamus showed positive correlation with RIFG only in normal subjects, inferred that the left thalamus might be an important mesomerism structure in the correlation of bilateral hemisphere;5、Left insula showed stronger positive correlation with RIFG in normal subjects than that in aphasia patients,suggested that dominant hemisphere insula is important in retaining in normal language function.
1、正常人在静息状态下即存在与LIFG和RIFG具有相关性的神经网络,该网络可能是维持正常语言功能的神经基础;2、脑梗死后运动性失语患者左侧梭状回、双侧额叶内侧回、右侧前扣带与LIFG的连接程度的减低可能是运动性失语的发生机制之一;3、与RIFG正相关的脑区在对照组为双侧半球分布,而在患者组仅出现在右侧半球,说明患者组RIFG与左侧半球的连接中断;4、RIFG与左侧丘脑的正相关性仅出现在正常对照组中,推测左侧丘脑可能是联系两侧半球功能区的重要中介结构;5、对照组与RIFG正相关性明显高于患者组的脑区位于左侧岛叶,说明优势半球岛叶对维持正常语言功能具有重要作用;第二部分脑梗死运动性失语患者语言恢复机制的静息态fMRI初步探讨目的:运用fMRI技术,采用种子点方法在静息状态下分析脑梗死运动性失语患者不同的恢复阶段语言功能连接方式。

The earliest and reliable Castanopsis fossil records date back at least to Eocene, and subfamily Castaneoideae fossil records found from Paleocene, it is indicated that appearance of Castanopsis is not later than Paleocene . All fossil records of Fagaceae and Castanopsis report from the Northern Hemisphere and their main distribution regions are in the Northern Hemisphere . It can be concluded that the Northern Hemisphere is the center of origin of Fagaceae and Castanopsis . However, owing to the discrepancy between fossil data and results of modern botany research as well as scarcity of fossil data from key area, precise center of origin of Castanopsis cannot be inferred.
栲属在地质历史上有着比现在广泛的分布,最早、最可靠的栲属化石记录发现于始新世地层,栗亚科化石在古新世就有发现,化石记录表明栲属起源的时间不晚于古新世,所有的壳斗科及栲属的化石都发现于北半球,现代分布也主要在北半球,壳斗科及栲属起源于北半球可以确认,由于化石证据与现代植物学的研究结果有较大差异以及关键地区化石证据的不足,具体的起源地尚不能肯定。
