全球能源互联网, 2020 将用户侧电、热、气等多种形式能源集成构建微能源系统，能够综合考虑多能流的转换、存储与传输过程中的互补特性，有利于提升系统的整体能源利用效率。然而，系统中不同形式能量的物理属性和传输特性差异较大，现有模型在研究多能流的传输和转换过程时，难以完整考虑热量传输约束及其对能量转换的影响。针对微能源系统中的综合能量管理问题，构建了热力系统中换热器的非线性传热模型，并考虑了热量传输对能量转换效率的影响。同时，结合光伏电池、储能电池、热泵、燃气锅炉、太阳能集热器及相变储热装置建立了微能源系统中能量传输与转换的整体模型，

Visible‐Light‐Excited Optical Thermometry in Ca3Sc2Si3O12: Er3+ via an Efficient Eu2+ Bridge
Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Er3+ ions are promising for optical thermometry due to their thermally coupled levels. However, their parity‐forbidden transitions result in weak and narrowband absorption, which restricts excitation to infrared lasers (e.g., 808, 980, or 1550 nm). Moreover, the single emission center inherently limits temperature sensitivity. In this work, we

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Phase‐change memory (PCM), characterized by its reversible transition between crystalline and amorphous phases, has emerged as a promising candidate for neuromorphic memory computing applications. However, conventional PCM devices lack an insufficient RESET/SET voltage ratio, which often leads to incorrect recording of the RESET state and ...

New Phytologist, Volume 247, Issue 6, Page 2616-2629, September 2025.Summary Seagrasses are important contributors to environmental nutrient cycling in marine ecosystems and can improve water quality by absorbing excess nitrogen (N). However, these ecosystems are vulnerable to human‐mediated pressures, including marine heatwaves (MHWs), particularly those of longer duration. We performed an experiment simulating a 30‐d,

Gongye shui chuli, 2016 通过对南海东部某海上油田换热器处水样、垢样进行分析,并结合水质的结垢趋势预测,研究了该油田换热器的结垢问题。结果表明,该油田换热器有明显的硫酸钙结垢倾向。针对该油田设备内流体水含量较低(含水率在10%~20%)的特点,开发了一种适合该环境的复合型阻垢剂。现场应用研究表明,当注药质量浓度为100 mg/L时,成垢离子Ca2+、SO42-的保有率均有明显提高,换热器的硫酸钙结垢倾向得到了有效控制。
