Piezoelectric ceramic and polymeric separators have been proposed to effectively regulate Li deposition and suppress dendrite growth,but such separators still fail to satisfactorily support durable operation of lithium metal batteries owing to the fragile ceramic layer or low-piezoelectricity polymer as ***,by combining PVDF-HFP and ferroelectric BaTiO_(3),we develop a homogeneous,single-layer composite separator with strong piezoelectric effects to inhibit dendrite growth while maintaining high mechanical *** squeezed by local protrusion,the polarized PVDF-HFP/BaTiO_(3)composite separator generates a local voltage to suppress the local-intensified electric field and further deconcentrate regional lithium-ion flux to retard lithium deposition on the protrusion,hence enabling a smoother and more compact lithium deposition morphology than the unpoled composite separator and the pure PVDF-HFP separator,especially at high ***,the homogeneous incorporation of BaTiO_(3)highly improves the piezoelectric performances of the separator with residual polarization of 0.086 pC cm^(-2)after polarization treatment,four times that of the pure PVDF-HFP separator,and simultaneously increases the transference number of lithium-ion from 0.45 to *** from the prominent piezoelectric mechanism,the polarized PVDF-HFP/BaTiO_(3)composite separator enables stable cyclic performances of Li||LiFePO_(4)cells for 400 cycles at 2 C(1 C=170 mA g^(-1))with a capacity retention above 99%,and for 600 cycles at 5 C with a capacity retention over 85%.

近年来,我国公路交通工程迅速发展,已经成为当前交通网络中不可或缺的重要选择。但软土地层上的公路路基填筑施工的风险依然较高,这主要是由于软土地层具有敏感性,且在雨水、堆载等的作用下,软土地层变形可能较大,因此可能导致完工后出现路面开裂、沉降、塌等事故。文章以某市软土地基上的路基填筑工程为研究对象,深入研究了软土地层条件下公路路基的况降变化,并针对桩基础加固方案,设置了不同桩体数量、不同桩体长度等对比工况,分析了对比了不同加固方案的加固效果,以期为类似工程施工提供参考。

Adaptive optimization of agile organization of command and control resource

引用

Journal of Systems Engineering and Electronics 2009年第3期20卷 558-564页

作者： yang chunhui Liu Junxian Chen Honghui Luo Xueshan Dept. of Management Naval Univ. of Engineering Wuhan 430033 P. R. China Key Lab. of C^4ISR National Univ. of Defense Technology Changsha 410073 P. R. China

Adaptive optimization is one of the means that agile organization of command and control resource （AOC2R） adapts for the dynamic battlefield environment. A math model of the adaptive optimization of AOC2R is put forward by analyzing the interrelating concept and research. The model takes the adaptive process as a multi-stage decision making problem. The 2-phases method is presented to calculate the model, which obtains the related parameters by running the colored Petri net （CPN） model of AOC2R and then searches for the result by ant colony optimization （ACO） algorithm integrated with genetic optimization techniques. The simulation results demonstrate that the proposed algorithm greatly improves the performance of AOC2R.
