为了探究不同支流洪水组合对干流区域的致灾影响,构建了一二维耦合水动力模型并进行验证.采用耦合模型分别对理想Y型流域和宁波市海曙区三江口区域进行建模,模拟了不同峰现时差的支流洪水过程,选取了干流洪峰流量、积水量、淹没面积、最大淹没水深和最大漫出距离5个指标来反映洪水在干流区域的致灾情况.研究结果表明:(1)所构建的一二维耦合模型可以较好地反映一维河道和二维地表的水量交换过程;(2)在理想算例中,随着支流洪水峰现时差的增加,洪水对干流区域的致灾情况明显减轻,所选取的5个指标分别削减了1.52%~22.34%、5.70%~75.48%、8.49%~97.60%、1.88%~36.45%和2.03%~37.56%;(3)随着余姚江和奉化江洪水峰现时差的增加,甬江区域受洪水的影响明显下降,所选取的5个指标分别削减了10.03%~21.47%、52.28%~94.16%、56.05%~97.55%、11.69%~28.46%和29.21%~76.64%.以期该研究为平原河网区域的防洪工作开展提供参考.

NbMoTaW难熔高熵合金(RHEA)在超高温下表现出优异的力学性能,但其室温脆性限制了其在航空航天等领域中的应用。采用激光选区熔化技术制备了(NbMoTaW)100-xCx和NbMoTaWTix两种难熔高熵合金(x%为原子数分数),通过合金化的方法提高了NbMoTaW合金的室温脆性抗性。研究表明:原子数分数为0.5%的C的加入显著提高了NbMoTaW合金的成形性和室温力学性能,使(NbMoTaW)99.5C0.5合金的屈服强度、极限抗压强度和塑性分别提高到1695 MPa、1751 MPa和6.9%;随着Ti含量的增加,NbMoTaWTix合金的强度和塑性也同时提高。研究结果为增材制造高强韧的NbMoTaW系难熔高熵合金提供了一种新的研究思路。

为研究短历时设计暴雨对地下空间内涝的影响规律,该文采用GAST模型和SWMM模型耦合的一维二维水动力模型,以陕西西咸新区沣西新城天福和园小区为研究对象,模拟小区地下车库在极端降雨条件下的洪水演进过程,探究临时挡水措施对小区地下车库进水量的影响。研究结果表明:与两场实测降雨数据对比,耦合模型的纳什效率系数为0.59和0.69,模拟结果较好,该模型可精确可靠地模拟地表地下洪水过程;随着设计降雨重现期的增加,地下空间进水量逐渐增大;在短历时设计暴雨情景下,当累计降雨量大于52 mm时,地下车库会有淹没风险;采用0.3 m临时挡水措施,可使小区地下车库在短历时设计暴雨10~50 a重现期条件下不发生淹没,使设计暴雨100 a重现期条件下的车库进水量削减39.23%;采用0.5 m挡水措施,可使小区地下车库不发生淹没,完全消除内涝风险。综上所述,一维二维耦合水动力模型可精细模拟地表地下洪水过程,为地下空间科学防涝减灾提供参考依据。

Background: Individuality in vocalizations may provide an effective tool for surveying populations of the Common Cuckoo(Cuculus canorus) but there remains few data on which technique to use to identify individuality. In this research, we compared the within-and between-individual variation in cuckoo calls using two different analytical methods, and discuss the feasibility of using call individuality to count male cuckoos within a ***: We recorded vocalization from 13 males, and measured 15 spectro-temporal variables for each call. The majority of these call variables(n = 12) have greater variation between individuals than within individual. We first calculated the similarity(Pearson's R) for each paired calls in order to find a threshold that could distinguish calls emitted from the same or different males, and then counted the number of males based on this distinction. Second, we used the more widely accepted technique of discriminant function analysis(DFA) to identify individual male cuckoos, and compared the correct rate of classifying individuals between the two analytical ***: Similarity of paired calls from the same male was significantly higher than from different males. Under a relatively broad threshold interval, we achieved a high(>90%) correct rate to distinguish calls and an accurate estimate of male numbers. Based on banded males(n = 3), we found the similarity of paired calls from different days was lower when compared with paired calls from the same day, but this change did not obscure individual identification, as similarity values of paired calls from different days were still larger than the threshold used to distinguish calls from the same or different males. DFA also yielded a high rate(91.9%) of correct classification of ***: Our study suggests that identifying individual vocalizations can form the basis of an appropriate survey method for counting male cuckoos within a population, provided the perf

Background: The success of cuckoo parasitism is thought to depend largely on the extent of egg matching between cuckoo and host eggs, since poor-matching cuckoo egg would lead to more frequent egg rejection by the host. In this study, we investigated how egg-spot matching between the Common Cuckoo(Cuculus canorus) and its host, the Oriental Reed Warbler(Acrocephalus orientalis) is affected by the local parasitism rate, nest availability in breeding synchronization and egg ***: We used the paired design of parasitized and their nearest non-parasitized nests where breeding occurred simultaneously to compare egg-spot matching. The image analysis was used to compare four eggshell pattern variables, namely spot size, density, coverage on the different areas of egg surface, and the distribution on the whole egg surface. Egg recognition experiments were conducted to test the effect of egg spots on egg rejection by the ***: Our results show that much better matching in almost all spot parameters tested on the side of the egg and the spot distribution on the whole egg occurred in parasitized nests than in non-parasitized nests. Matching of spot density between cuckoo and host eggs in parasitized nests increased with the synchronization between temporal availability of nests and the egg-laying period of female cuckoos. Egg recognition experiments in which the warbler eggs were deliberately painted with extra spots led to a significantly higher egg rejection rate(78.3%) than of unpainted ***: Our data suggest that both the high temporal encounter rate between cuckoo and warbler nests as well as the high egg rejection ability of the host are important factors for egg-spot matching of the cuckoos.
