Abstract: The resistance behaviour of nanocrystal nickel was studied from 4 to 720 K and 0 to 20 Kbar.A linear variation of the resistance was found at low temperatures.It showed that under high temperatures, that system transformed to a more stable state,with the relaxation process taking place by stages and influenced by exerted pressures.The property,especially the stability,of nanocrystal was closely re- lated to the compacting pressure,
