The extensive use of traditional co.king and heating stoves to meet domestic requirements creates a serious problem of indoor and outdoor air *** study reports the impacts of two fuel feeding methods-front-loading and top-loading on the thermal and emissions performance of a modern co.l-fired water-heating and co.king stove using a co.textual test sequence that replicates typical patterns of domestic *** as a low-pressure boiler,when this stove was fueled with raw co.l,the findings indicate that front-loading the fuel,which devolatilizes the new fuel gradually,produced co.sistently higher space heating efficiency and lower emission factors than top-loading the same stove,which devolatilizes new fuel all at *** the performance at both high and low power gave the similar results:front-loading with raw co.l produced co.sistently better results than *** average water heating efficiency when front-loading was(58.6±2.3)%and(53.4±1.8)%for *** the sixteen-hour test sequence,front-loading produced 22%lower emissions of PM2.5(3.9±0.6)mg/MJNET than top-loading(4.7±0.9)mg/*** same pattern was observed for carbon monoxide and the co.co. *** was reduced from(5.0±0.4)g/MJNET to(4.1±0.5)g/*** co.bustion efficiency(co.co. ratio)improved from(8.2±0.8)%to(6.6±0.6)%.Briquetted semi-co.ed co.l briquettes are promoted as a raw co.l substitute,and the tests were replicated using this ***,the same pattern of improved performance was *** loading produced 3.5%higher heating efficiency,10%lower co.and a 0.9%lower co.co. *** is co.cluded that,co.pared with top loading,the manufacturers reco.mended front-loading refueling behavior delivered better thermal,emissions and co.bustion performance under all test co.ditions with those two fuels.

提出了一种基于双向正交泵浦半导体光放大器(SOA)的相位保持幅度再生方案,实验分析了泵浦、信号及其端面反射场之间的多重四波混频(FWM)转换过程,探索了同向场作用下的共轭光再生能力.测量了注入不同信号光功率、信号质量情况下获得的幅度噪声压缩效果以及相位输出特性,印证双向正交泵浦SOA再生器的相位保持幅度再生功能,通过实验测量得到2.2 dB的幅度噪声压缩结果.进一步通过仿真分析系统,探讨了多进制数字相位调制(MPSK)信号的工作特性,表明该再生器可在相同工作参数下支持高阶信号的再生需求.
