摘要
通过不同方法对ＳＤ型大鼠分四组进行实验处理，观察比较大鼠的行为，发现：在突然的高强度噪音条件下，大鼠出现恐惧的行为反应；强刺激组大鼠恐惧行为较控制组明显增多，行为的唤醒适应能力异常，并存在显著的个体差异；噪音脱敏训练对提高大鼠在高强噪音条件下的应激能力、减少恐惧具有良好的促进作用；在脱敏训练中尤以逐渐递增噪音强度、刺激时间与平均分配实验日结合的方法效果最为显著。
This was a study of the behavior of foer groups of SD type rats by differential methods under high intensity noise. Our findings: 1)Under high intensity noise, the rats showed fear behavior 1 2) The group exposed to strong stimulation showed far more fear behavior than the control groups 1 3)Training in desensitization from noise was conducive to the rats'adaptability and reduction of fear under high intensity noise;4)The best training method was a combination of gradually increasing noise intensity and stimulation time, and equally distributing experimental days.
