By using data of hourly rainfall with all of the meteorological stations in the upper reaches of Hunhe River (Qingyuan Section), the digital elevation model, the land use and the disasters data etc., the storm flood process which happened on 16 August 2013 is reproduced simulated based on the rainstorm flooding of FloodArea model, also the flooding simulation and its effectiveness have been carried out. Conclusions are drawn as follows: there is a sharp rise of the flood depth falling behind the change of rainfall three or four hours. As the accumulation of the precipitation, the water level has increased, and when the precipitation process stops, the flood pooled into midstream and downstream gradually. According to the disaster investigation, in both the aspects of flooding scope and flooding depth of warning spots, the simulation result of FloodArea model agrees with the fact. It indicates that the FloodArea model generates good simulation effect in the upper reaches of Hunhe River (Qingyuan Section). Combined with population and GDP information, in the whole river, about eighty-three thousand people were affected by flooding, also one billion and five hundred seventy five million RMB of gross domestic product was lost. When the flood depth deepens and the flooding scope increases, correspondingly the loss rate of population and GDP rises and the flood risk increases.

Based on the meteorological and geographic information data, with statistical method and the FloodArea model, the extreme daily rainfall of the 100-year return period in Hunhe River basin was established, through the simulation of rainstorm and flood disaster, characteristics of flood depth in warning spot Cangshi village in the upstream of the river were analysed, and possible effect on community economy was also evaluated. Results showed that, the precipitation of 100-year return period occurred, the flood depth has been below 1.0 meter in the most areas of Hunhe River basin, the depth was between 1.0 meter and 2.5 meters in the part areas of Hunhe River basin, and the flood depth has been exceed 2.5 meters in a small part of Hunhe River basin. After the beginning of precipitation, the flood was concentrated in the upper reaches of the river. With the accumulation of precipitation and the passage of time, the flood pools into midstream and downstream. Precipitation lasted for 24 hours, the warning spot was flooded in the beginning of precipitation. With the accumulation of precipitation, water level of the river increases gradually. The depth of warning spot has passed 1.0 meter at the 07 time of the whole process, and the maximum value of flood depth at warning spot was 1.083 meters that occurred at the 19 time. The flood depth of warning spot decreased gradually after the precipitation stopping, and the depth has been below 0.2 meters, the flood of upstream ended. Up to the end of the upstream flood process, in the whole river, about one million five hundred and sixty thousand people were affected by flooding, and thirty-eight billion and two hundred million RMB of gross domestic product were lost, in addition, dry land and paddy field were affected greatly, but woodland and grassland were less affected.

通感隐喻是一种普遍认知方式。感官感觉互相联系,彼此贯通,是通感产生的生理基础。对客观事物的感知可以通过感官际沟通,引起基于相似性的心理联想,是通感产生的心理机制。通感隐喻的认知过程把某一感官域的意象投射至其它感官域,是不同的感官意象之间的转换,且该转换过程具有层级性。通感隐喻意象的转换过程具有很强的美学功能,它以审美体验为基础,是审美想象的结果,同时强化了审美表达。

Visibility graph（VG） is a widely applicable tool for studying complex time series due to its advantages of few parameters and easy implement. However, the topological links of VG based methods are roughly represented as binary *** order to better inherit the advantages of visibility graph and more accurately dig out the internal characteristics of time series,a novel method of constructing an weighted complex network based on visibility angle measurement, i.e., visibility angle based weighted visibility graph（VA-WVG）, is proposed. Firstly, the data points of the original time series are represented as the nodes of the complex network. Secondly, after judging that the two data points satisfying the visibility criterion, visibility angle between the two data points is measured, which is used as the weight of the network connection. Mapping logistic signals under different parameter settings into VA-WVG, and extracting the network feature of strength distribution entropy, we find that the VA-WVG can not only accurately discriminate periodic signals from the chaotic signals, but also can precisely reflect the number of periodic state solutions and complexity of chaotic state, while the traditional VG can only roughly distinguish between periodic states and chaotic states. Next, the proposed method is applied to classify different types of EEG signals. Combining the extracted features and support vector machine, we identify epileptic EEG signals from healthy EEG signals with classification accuracy of100%, while the accuracy of the VG method is only 83.84%.

为了增强无线传感网络(WSN)的自适应性,降低WSN功耗,需要进行配网路由修复。传统的路由修复算法采用能量感知模型,设置负载平衡的CTP路由协议估算剩余能量,算法没有考虑路由最大角度的负载平衡问题,路由修复性能不好。提出一种基于负载-功耗联合特征测试的WSN配网路由修复算法,设计了基于ICTP协议的WSN网络模型框架,综合考虑簇头的剩余能量及其与Sink的距离对它的生命周期的影响,进行路由选择设计,采用负载-功耗联合特征测试方法,实现WSN配网路由修复改进。实验结果表明,该算法进行WSN路由修复设计,节点剩余能量方差一直维持在最低,有效地均衡了网络负载,平衡了网络能量消耗,节点生存性较大,提高能量的有效利用率。
