1Designing method of acceleration and deceleration control schedule for variable cycle engine显示文摘Studies show that different geometries of a Variable Cycle Engine(VCE)can be adjusted during the transient stage of the engine operation to improve the engine performance.However,this improvement increases the complexity of the acceleration and deceleration control schedule.In order to resolve this problem,the Transient-state Reverse Method(TRM)is established in the present study based on the Steady-state Reverse Method(SRM)and the Virtual Power Extraction Method(VPEM).The state factors in the component-based engine performance models are replaced by variable geometry parameters to establish the TRM for a double bypass VCE.Obtained results are compared with the conventional component-based model from different aspects,including the accuracy and the convergence rate.The TRM is then employed to optimize the control schedule of a VCE.Obtained results show that the accuracy and the convergence rate of the proposed method are consistent with that of the conventional model.On the other hand,it is found that the new-model-optimized control schedules reduce the acceleration and deceleration time by 45%and 54%,respectively.Meanwhile,the surge margin of compressors,fuel–air ratio and the turbine inlet temperature maintained are within the acceptable criteria.It is concluded that the proposed TRM is a powerful method to design the acceleration and deceleration control schedule of the VCE.Linyuan JIA Yuchun CHEN Ronghui CHENG Tian TAN Reran SONG 2021Chinese Journal of Aeronautics2021,34,5:5

3Ultra-small PbSe Quantum Dots Synthesis by Chemical Nucleation Controlling显示文摘Ultra-small PbSe quantum dots (QDs) were synthesized using conventional hot-injection method.A small amount of Sn was used as a nucleation promotion agent to control nucleation and growth during the QDs synthesis process.The average diameter of the QDs is about 1.6 nm,of which absorption peak centers at 550 nm and photoluminescence peak centers at 750 nm under 350 nm laser excitation with power as low as 500 μW.Transmission electron microscopy images confirm that the QDs size well matches with the calculated diameter from Brus equation.This match and electron energy loss spectroscopy analysis proves that Sn is not involved into the final structure of the ultra-small PbSe QDs.An ion-exchange process was proposed for the nucleation control and ultra-small QDs synthesis.The prepared ultra-small QDs could be a promising candidate for luminescence,solar cell devices,and others.程方亮 YU Miao JIA Linyuan TIAN Qihang 张继红 Bokhyeon Kim ZHAO Xiujian 2021Journal of Wuhan University of Technology(Materials Science)2021,36,4:0
