The result s show that the cerium compounds consist of Ce 3/ Ce 4 and Ce 2O 3/ CeO 2 , exist in the form of particles and are excellently dist ributed on the zinc powder subst rate. The capacity-loss of the zinc elect rodes is evidently suppressed while the discharge capacity and cycle life can be markedly improved due to the application of the zinc-based composite powder as negative materials of the silver-zinc bat tery. Especially , discharge capacity of 231. 4 mAh g-1 is still achieved at the 50th cycle for the zinc elect rode using the composite powder .

On the basis of analyzing the thermodynamic properties and cycle performance of pure refrigerants, the paper optimizes their concentration while screening NARMs used in wide variable-temperature heat source. The practical applications of NARMs, such as R22/R123, R123/R125 etc., are studied in geothermal heat pump, seawater heat pump, air dehumidification system and dual-evaporator domestic refrigerator. The results show that the NARMs can match the limitation of a pinch point at the air-side exit of heat exchanger, reduce the unreasonable heat transfer temperature difference, and improve the COP of system. The above conclusion is proved by measuring the cycle performance of R12, MP39 and R11/R22 in a two-evaporator experimental system.
