Numerical results show that the bidirectional attenuation seat reduces the head-pelvis acceleration markedly, and has little influence on vertical attenuation pole and chest-back acceleration. 通过数值算例,比较了竖直缓冲座椅和双向缓冲座椅的缓冲效果,讨论了座椅头部点和转动中心点的响应规律。
In the pedestrians who died, head injury was 71.6 %, followed by chest-back and abdomen-waist injuries, and they were the main cause of death. 死亡者中,头部伤发生率高达71.6%,胸背(CB)和腹腰伤次之,是死亡的主要原因;
Objective To observe the efficacy of nerve block combined with medicine therapy and psychological intervention in the elderly with residual chest-back post-herpetic neuralgia ( PHN ). 目的观察椎旁神经阻滞及皮损区局部浸润联合药物和心理学综合疗法对老年胸背(CB)部带状疱疹后神经痛的疗效。
The treatment efficacy of nerve block combined with medicine in the elderly with residual chest-back post-herpetic neuralgia 神经阻滞联合药物治疗老年胸背(CB)部带状疱疹后神经痛的临床观察
The results indicate that the chest-back acceleration of the seat can be decreased by reducing the buffer force threshold, but the head-pelvis acceleration is unchanged. 结果表明,减小缓冲力阈值,可以减小座椅的胸背(CB)向加速度,但对头盆向加速度影响不大;
