Maisotsenko cycle(M-cycle)has been combined with some cooling and power cycles,and behaves important thermodynamic ***-time thermodynamics(FTT)is applied to establish three endoreversible models of M-Atkinson,M-Dual and M-Miller *** are performed based on models of endoreversible Atkinson,Dual and Miller cycles by combing FTT model with M-cycle *** output(POW)and thermal efficiency(TEF)of those M-cycles are studied and optimized by numerical *** maximum power output(MPO)and the corresponding pressure ratio and TEF,the maximum TEF and the corresponding pressure ratio and POW,as well as optimal ranges of pressure ratio are *** of mass flow rate of circulating water injection,initial cycle temperature and maximum cycle temperature on cycle POW,TEF and optimal pressure ratio range are *** optimal performances of the three M-cycles are compared with those of traditional Atkinson,Dual and Miller cycles under the same *** results show that for the three M-cycles,end temperature of adiabatic expansion process of M-cycle is less than that of the corresponding traditional cycle,POW and TEF at arbitrary pressure ratio of M-cycle are much higher than those of the corresponding traditional cycle,and performance characteristics of M-cycles are superior to those of the corresponding traditional cycles.

In this paper,cationic polycarboxylate superplasticizer has been synthesized by using room temperature process with HPEG,AA,DAC and 3-S as the main raw *** investigated the effect of the dosage of different raw materials on the dispersing property of polycarboxylate superplasticizer,and we knew that AA:DAC HPEG:3-S=4.5:0.05:1:0.12 was the best molar ratio,the synthesized cationic polycarboxylate superplasticizer had excellent dispersity and mud resistance,and it was superior to commercially available ordinary polycarboxylate superplasticizer

关键词： Polycarboxylate superplasticizer cationic room temperature process concrete admixture
