负性情绪图片诱发心血管和内分泌反应及与记忆成绩的关系

, 2006
目的:考察负性情绪图片刺激下个体交感神经系统、HPA轴反应与其记忆成绩之间的关系。方法:采用负性情绪图片作为刺激材料,测定刺激前后56名健康女大学生主观情绪感受、心率、收缩压、舒张压、唾液皮质醇水平的变化,比较负性情绪图片和中性对照条件下的记忆成绩。结果:1·与中性图片相比,负性情绪图片刺激可诱发明显负性情绪,被试收缩压升高(99±

激光辐照下轴压薄壁圆柱壳屈曲行为研究

, 2013
针对轴压薄壁圆柱壳结构,首先通过实验研究了其临界屈曲载荷和屈曲模态,并和理论及数值模拟进行了对比,结果基本一致。轴压柱壳屈曲行为对局部缺陷敏感,入射激光相当于引入了局部缺陷,可能大大影响屈曲行为。通过实验和数值模拟研究了入射激光对轴压薄壁圆柱壳屈曲行为的影响,结果表明:(1)实验中辐照区温度上升引起材料热软化,降低了局部强度,从而大大降低了轴压柱壳的临界屈曲载荷;(2 ...
