| 1 | Flexible lead-free BFO-based dielectric capacitor with large energy density,superior thermal stability,and reliable bending endurance显示文摘As an essential energy-stored device,the inorganic dielectric film capacitor plays an irreplaceable role in high-energy pulse power technology area.In this work,propelled by the challenge of overcoming the bottlenecks of inflexibility and inferior energy storage density of the pure BiFeO3 films,the mica with high bendability and thermal stability is adopted as substrate,and the relaxor ferroelectric(Sr_(0.7)Bi_(0.2))TiO_(3) is introduced to form solid solution to introduce relaxor behavior.The subsequently fabricated 0.3Bi(Fe_(0.95)Mn_(0.05))O_(3)-0.7(Sr_(0.7)Bi_(0.2))TiO_(3)(BFMO-SBT)thin film capacitor exhibits a high recoverable energy storage density(W_(rec)=61 J cm^(-3))and a high efficiency(η=75%)combined with a fast discharging rate(23.5 μs)due to the large polarization difference(ΔP=59.4 μC cm^(-2)),high breakdown strength(E_(b)=3000 kV cm^(-1)),and the strong relaxor dispersion(γ=1.78).Of particular importance is the capacitor presents excellent stability of energy storage performance,including a wide working temperature window of -50-200℃,fatigue endurance of 108 cycles,and frequency range of 500 Hz-20 kHz.Furthermore,there are no obviously deteriorations on energy storage capability under various bending states and after 104 times of mechanical bending cycles.All these results indicate that BFMO-SBT on mica film capacitor has potential application in the future flexible electronics. | Changhong Yang Jin Qian Panpan Lv Haitao Wu Xiujuan Lin Kun Wang Jun Ouyang Shifeng Huang Xin Cheng Zhenxiang Cheng | 2020 | Journal of Materiomics2020，6，1： | 4 |

| 7 | A reduced-order method for estimating the stability region of power systems with saturated controls显示文摘In a modern power system, there is often large difference in the decay speeds of transients. This could lead to numerical problems such as heavy simulation burden and singularity when the traditional methods are used to estimate the stability re- gion of such a dynamic system with saturation nonlinearities. To overcome these problems, a reduced-order method, based on the singular perturbation theory, is suggested to estimate the stability region of a singular system with saturation nonlinearities. In the reduced-order method, a low-order linear dynamic system with saturation nonlinearities is constructed to estimate the stability region of the primary high-order system so that the singularity is eliminated and the estimation process is simplified. In addition, the analytical foundation of the reduction method is proven and the method is validated using a test power system with 3 buses and 5 machines. | GAN DeQiang XIN HuanHai QIU JiaJu HAN ZhenXiang | 2007 | Science China(Technological Sciences)2007，50，5： | 1 |
