摘 要：<正> The resistance behaviour of nanocrystal nickel was studied from 4 to 720 K and 0 to 20 Kbar.A linearvariation 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 andinfluenced by exerted pressures.The property,especially the stability,of nanocrystal was closely re-lated to the compacting pressure,
