55727 研究表明,级联抗毁性的度量指标必须同时考虑权重和拓扑结构的因素,否则将可能高估故障的严重程度。 Studies have shown that cascade anti-destroying ability of metrics must also consider the factor of weight and topology, otherwise will may overestimate the extent of the fault.
55728 在BBV(Barrat-Barthélemy-Vespignani)网络的框架内,得出如下结论:当α>1时,攻击负荷大的节点更容易引发大规模级联故障; In BBV (Barrat - Barthelemy - Vespignani) within the framework of the network, the following conclusions:
55729 而当α<1时,攻击负荷小的节点更容易导致网络的瘫痪;且BBV模型参数δ与网络级联抗毁性负相关。 when the alpha > 1, big attack load nodes are more likely to cause large-scale cascading failures;And when the alpha < 1, smaller load nodes are more likely to lead to the network paralysis;BBV model parameters and the delta is negatively related to the network cascade anti-destroying ability.
55730 最后从不同角度对上述结论进行了理论分析和仿真说明。 Finally the above conclusion from different angles on the theoretical analysis and simulation.
55731 由于冲激雷达回波信号中无法提取出多普勒频率信息,传统的基于频域成像的方法不再适用于冲激雷达成像系统。 Because the impulse radar echo signal can not extract the doppler frequency information, the traditional method based on frequency domain imaging no longer applicable Yu Chongji radar imaging system.

55734 节点的社会性与能量有限性严重影响延迟容忍网络(delay tolerant network,DTN)性能。 The social nature of nodes and energy limited seriously affect the delay tolerant network (delay tolerant network, DTN) performance.
55735 提出了关系强度感知的DTN能量有效性路由机制,利用消息平均转发时间衡量节点间的关系紧密程度,并根据邻居节点的能量状态和相遇概率优化转发决策,同时采用社会属性关联的消息优先级机制提高缓存利用率。 Put forward the relationship between the intensity of awareness of the energy efficiency DTN routing mechanism, using the average forwarded message time measure of how closely the relationship between nodes, and according to the neighbor node energy state and meet the probability optimization forwarding decision, at the same time using social attributes associated message priority mechanism improve the cache utilization.
55736 结果表明,所提出的路由机制显著地延长了网络存活时间,改善了消息投递率和网络开销性能。 Results show that the proposed routing mechanism significantly prolonged the survival time of network, improve the message delivery rate and the performance of network overhead.
