为研究布置真空绝热板对冷藏集装箱内温度分布的影响,以20ft机械式冷藏集装箱为研究对象,建立箱内空气对流与换热的物理和数学模型。采用标准k-ε紊流模型,对稳态下的真空绝热板冷藏集装箱和聚氨酯冷藏集装箱内温度场分布情况进行模拟仿真。模拟结果表明:采用真空绝热板作为保温材料,冷藏集装箱箱内温度场分布状况明显优于聚氨酯冷藏集装箱,而且平均温度能够降低0.8K。最后,对20ft实体聚氨酯冷藏集装箱进行实验,仿真与实验结果能够较好吻合,验证了模型的准确性。

对小分子给体进行氟代,往往能够通过拉深其最高占据分子轨道(HOMO)能级来提高光伏器件的开路电压,从而有助于获得更高的光电转化效率。本工作设计合成了含3′,4′-二氟-3,3″-二辛基三联噻吩结构的新型共轭单元,并通过Stille偶联、Knoevenegal缩合等反应进一步合成了以噻吩取代侧链的苯并二噻吩为核心、氟代三联噻吩为共轭桥、罗丹宁为封端基团的新型小分子电子给体光伏材料(命名为BDT4F-RO)。此分子的结构和初步的理化性能分别通过核磁共振波谱(^(1)H NMR、^(13)C NMR、^(19)F NMR)、紫外-可见吸收光谱、循环伏安法和热重分析等进行测试表征。结果表明:薄膜状态下的BDT4F-RO在300~700 nm均有较强的吸收,吸收边界位于690 nm。与不含氟原子的类似物BDT-RO相比,BDT4F-RO具有较深的HOMO能级,这也使得对应的光伏器件有更高的开路电压(0.95 V)。但是总体的效率上BDT4F-RO远逊于BDT-RO,这可能是氟原子的引入使得BDT4F-RO与受体分子IDIC的混溶性较差所致。

Relay Node Placement with Base Stations in Wireless Sensor Networks Fault-Tolerant

引用

Chinese Journal of Electronics 2014年第4期23卷 794-800页

作者： GAO zhipeng CHEN kan QIU Xuesong State Key Laboratory of Networking and Switching Technology Beijing University of Posts and Telecommunications

It has been proposed to deploy relay nodes for the sake of prolonging Wireless sensor networks(WSN)lifetime, such that sensors transmit the sensed data to them which in turn delivers the data to base stations. For survivability requirements, relay placements which considers fault tolerant ability have been noticed and studied. While related works are limited or most existing works don't take factors such as fault tolerance, or base stations into account comprehensively in two tired WSN. We focus on fault tolerant relay node placement in two-tiered heterogeneous WSN with base stations. As far as we know,fault tolerance contains two fundamental aspects, for one is multi-coverage and the second is multi-path. It is a NPhard problem and figure out an approximation, whose approximation ratio is enhanced to be(18 +). While a sub-problem approximation is also described as supplementary. Experimental results verify that the number of relay nodes deployed by our algorithm is somewhat superior to existed relay node placement solutions.
