Abstract: Rock may lose its memory property if it has undergone loading and heating process frequent-ly.Because these frequent actions can cause a lot of damage in the rock. All kinds of interference must be disposed if we use the Kaiser effect to determine the geostress and heat states of the rock.

Key words: Stress, Tkermal effett, Acoustic emission, Kaiser effect

摘要： 对花岗岩进行反复加压和加热来模拟岩石在漫长的地质历史进程中,经受反复多变的应力和热的作用,使岩石内部受损伤,从而导致岩石记忆性能的丧失。用岩石凯塞效应确定岩石曾受过的地应力和热状态时需要排除干扰。
