阿拉伯什叶派乌里玛政治化经历了一个渐进的过程。19世纪末和20世纪初,中东什叶派乌里玛曾在伊朗烟草抗议事件、伊朗立宪运动和伊拉克反英斗争三大事件中表现出空前的政治热情。20世纪50年代末和60年代初,因受到世俗化冲击下的宗教危机... 阿拉伯什叶派乌里玛政治化经历了一个渐进的过程。19世纪末和20世纪初,中东什叶派乌里玛曾在伊朗烟草抗议事件、伊朗立宪运动和伊拉克反英斗争三大事件中表现出空前的政治热情。20世纪50年代末和60年代初,因受到世俗化冲击下的宗教危机、乌里玛自身生存危机和日益严重的教派政治危机的影响,什叶派乌里玛开始积极参与政治。伊拉克两大什叶派圣城纳杰夫和卡尔巴拉是什叶派乌里玛政治化的源头,阿拉伯什叶派乌里玛通过"纳杰夫网络"和设拉子派实现了政治化。阿拉伯什叶派乌里玛的政治化产生了多重影响。 展开更多

The analysis of the “tree-like network” construct method has been repeated. The high effective conduction channel distribution has been optimized again, without the premise that the new order assembly construct must be assembled by the optimized last order construct. It is proved that the “tree-like network” construct method is faultiness. A more optimal construct is obtained,; when the thermal conductivity; the proportion of the two heat conduction materials are constant, the limit of the minimum heat resistance is derived. All these conclusions can be used to guide the engineering application. 展开更多

An efficient scheme of wavelength reuse is presented for solving the capacity limitation of WDM star single-hop networks by limited wavelengths. According to this scheme, the nodes supported by the network can be at least doubled under limited wavelength numbers. Under the same number of nodes, the delay of network can be greatly lowered, the throughput of the network can be increased 1-3 times, and the properties of the network can be efficiently improved. 展开更多
