Here, the material design concept of functional units has been applied to prepare a zero-dimensional (oD) organic anti-mony halide (1-BMP)_(5)(SbCl_(5))_(2)SbCl_(4) with two luminescent centers from the inorganic units and the organic units, emitting red emission about 670 nm and cyan emission about 508 nm respectively, combined to form white light. Based on the photoluminescence (PL), the time-resolved PL analysis and density functional theory (DFT) calculation, it is shown that the red and cyan emission comes from STEs related to inorganic units [SbCl_(5)]^(2-) and the fluorescence of organic cations 1-BMP^(+), respectively. This work provides new methods and ideas for the development of low-cost and eco-friendly white emission phosphors for single-component solid-state WLEDs.展开更多
将故障期间由发电机转子上的不平衡转矩形成的能量作为过剩暂态能量(STE),以其作为反映发电机受到故障扰动程度的指标。故障切除后,STE 减去能量耗散项后等于暂态能量(TE)。利用 TE 对汽轮机调速系统附加 H∞控制(TGAHC)对稳定性的作用...将故障期间由发电机转子上的不平衡转矩形成的能量作为过剩暂态能量(STE),以其作为反映发电机受到故障扰动程度的指标。故障切除后,STE 减去能量耗散项后等于暂态能量(TE)。利用 TE 对汽轮机调速系统附加 H∞控制(TGAHC)对稳定性的作用原理进行了理论分析。分析结果表明:TGAHC 能够加速暂态能量的衰减,有助于减少故障后发电机转子的振荡时间,具有提高电力系统稳定性的作用。单机系统的数字仿真结果验证了理论分析结果。展开更多
