蓄电池内阻与容量的关系

蓄电池的内阻跟额定容量有关。荷电态SOC高于50%时,阀控密封铅酸蓄电池、锂离子电池、金属氢化物镍电池、镉镍蓄电池、锌镍电池的内阻都是保持不变的;只是SOC低于40%以下时,它们的内阻才很快升高。     

Improving hydrogenation efficiency of polycrystalline silicon thin film transistors by a new approach

In this paper, a new hydrogenation process of poly-Si thin film for the fabrication of poly-Si thin film transistors (TFTs) is proposed. In the new approach, the hydrogenation of TFTs is performed before deposition of contact metal. N-channel and p-channel poly-Si TFTs with various channel lengths and widths were fabricated with the new and conventional processes for comparison. The results verified that the efficiency of hydrogenation has been improved remarkably by the new process. The field-effect mobility of carriers, the on state current, threshold voltage and the on/off states current ratio have been greatly improved, and the trap state density has been reduced significantly.     

Suppression of efficiency roll-off in TADF-OLEDs using Ag-island nanostructures with localized surface plasmon resonance effect

Organic light-emitting diodes (OLEDs) based on thermally activated delayed fluorescence (TADF) have emerged as promising alternatives to phosphorescent OLEDs for harvesting both singlet and triplet excitons. However, the development of TADF-OLEDs meets a thorny problem of serious efficiency roll-off at high luminance. Here, we demonstrate an approach to suppress the efficiency roll-off characteristics in TADF-OLEDs by localized surface plasmon resonance (LSPR) effect of easy-fabricated Ag-island nanostructures. Compared with the common TADF-OLEDs at a high current density of 100 mA cm⁻², the efficiency roll-off ratio of the TADF-OLEDs with Ag-island nanostructures decreases from 49.75% to 35.76% significantly, and the maximum current efficiency is increased by 10.5%. The performance enhancement is mainly attributed to the coupling between excitons and localized surface plasmons (LSPs), which could alter the excited state kinetic characteristics of TADF molecules.

利用热场动力学的方法研究了介观RLC电路在有限温度下的相干态和压缩态中电荷和磁通量的量子涨落.结果表明,介观RLC电路中电荷和磁通量的量子涨落不仅与电路中的元件参数而且可能与环境温度和压缩参数有关,而这些量子涨落与平移参数无关.     

An Evolution Strategy for the Induction of Fuzzy Finite-State Automata

Grammar inference (GI) encompasses theory and methods for the inference of any structure that can recognize a language-be it a grammar, an automaton, or some other procedure-from training data. It has many applications[1,2]. And many methods are developed to carry out it[3~5]. However, relative fewer efforts have been made to infer a grammar using evolution strategies (ES). We believe that ES is suitable for the inference of a language due to their direct coding scheme and their simple way …
