为了降低冬季供热对热电联产机组发电出力的影响,提出了一种基于吸收式换热的热电联产低温供热技术,借助吸收式换热机组,实现一次网供水温度和回水温度的双降低,提高采暖季乏汽供热占比,进而提高热电联产机组能源利用效率和经济收益。以西北某热电厂两台300 MW热电机组为例进行了应用案例分析,分析结果表明:项目改造完成后,单个采暖季因供热而减少的发电量由改造前的2.13亿度电降至0.97亿度电(降幅54%),在不增加燃煤消耗量且保障原有的供热负荷的前提下,单个采暖季可多发1.16亿度电;每年可新增收益4766万元,项目静态投资回收期3.7年,改造经济性十分可观。理论分析和应用案例分析结果表明,此种基于吸收式换热的热电联产低温供热技术,可显著提高热电联产机组乏汽供热占比和能源利用效率,促进我国集中供热行业的节能减排。

The von Neumann bottleneck is a critical limitation in synaptic devices. Therefore, artificial synaptic devices resembling biological neuromorphic synapses have been developed to overcome the von Neumann bottleneck. However, synaptic devices require voltages, which results in considerable energy consumption. Here, photonic synaptic devices with the vertical structure of indium tin oxide（ITO）/SnO2/Al2O3/CsBi3I10/Au are fabricated, which can work in the self-powered mode owing to the photovoltaic effect endowed by a vertical multilayer structure. Several fundamental synaptic functions, such as excitatory postsynaptic current, paired-pulse facilitation, short-term plasticity（STP）, long-term plasticity（LTP）, pulse-frequency-dependent plasticity, transition of STP to LTP, and the learning experience are emulated. Moreover, Morse-coded external light information is decoded by self-powered photonic synaptic devices. The results indicate that self-powered photonic synaptic devices based on lead-free perovskites exhibit great potential for efficient neuromorphic computing and optical wireless communication.

Wuhan University Journal of Natural Sciences 2017年第3期22卷 215-222页

作者： LIU Hui liang dandan CHEN Shiyun BIAN Jian FENG Yuan FANG Baolong Department of Mathematics and Physics Hefei UniversityHefei 230601 Anhui China High Magnetic Field Laboratory Chinese Academy of Sciences/University of Science and Technology of China Hefei230031 Anhui China Analysis and Testing Center Hefei University Hefei230601 Anhui China

We study the structure, magnetization, electrical transport properties and heat capacity of the pyrochlore iridates A2Ir2O7（A=Y, Eu, Bi）. It is found that magnetic frustration and long-range magnetic order coexist in Y2Ir2O7 and Eu2Ir2O7, while Bi2Ir2O7 shows magnetic frustration or short-range magnetic order without long-range magnetic order. The former two compounds show insulating behavior. However, the latter one shows metallic behavior. The variations of the radius of A-site ion affect the conduction bandwidth, correlation and Ir-Ir exchange energy, which in turn determine transport properties and magnetic properties. We also find that the antiferromagnetic ordering of pyrochlore iridates is weakly frustrated. The all-in/all-out type of anisotropy based on spin-orbit coupling plays a key role in releasing the frustration.
