<< review queue entry 86457 - submitted by 'jjbeard' >> 损耗指信号或能量在传输、转换过程中强度衰减的现象，通常以分贝（dB）为单位量化。在通信领域表现为光功率递减或电磁波强度减弱，直接影响传输距离与质量；在电力系统中则涉及功率耗散和能量损失 [1-3] [5]。 固有损耗由材料特性决定，包括光纤的瑞利散射、杂质吸收及半导体器件的电阻损耗；附加损耗源于外部因素，如光纤弯曲、接续误差或电力设备开关频率影响 [1] [5-7]。无线通信路径损耗包含自由空间衰减、大气吸收和反射损耗，计算公式涉及传输距离与频率变量 [3-4]。功率器件耗散计算需综合静态损耗、动态损耗及热阻参数 [1-2]。 1966年高锟提出材料提纯降低光纤损耗理论，1970年康宁公司研制出20dB/km石英光纤。2025年空芯光纤实现0.05dB/km衰减系数，热塑性聚丙烯电缆载流量提升1.2倍，极低损耗硅钢使配电变压器损耗降低15% [8-9]。 https://baike.baidu.com/item/%E6%8D%9F%E8%80%97/2731413 Hopefully removing the space is correct: https://cc-cedict.org/wiki/syntax says to have a space but the change log seems to show they're being removed when the syllables are one "word"? ------------ Editor: That link is for our old v1 format, but we are transitioning to v2. There's a link for info on the v2 format near the top of the v1 format webpage. |
