We performed a 2-year follow-up survey of 523 patients with peripheral nerve injuries caused by the earthquake in Wenchuan, Sichuan Province, China. Nerve injuries were classiifed into three types： type I injuries were nerve transection injuries, type II injuries were nerve compression injuries, and type III injuries displayed no direct neurological dysfunction due to trauma. In this study, 31 patients had type I injuries involving 41 nerves, 419 had type II injuries involving 823 nerves, and 73 had type III injuries involving 150 nerves. Twenty-two patients had open tran-section nerve injury. The restoration of peripheral nerve function after different treatments was evaluated. Surgical decompression favorably affected nerve recovery. Physiotherapy was effective for type I and type II nerve injuries, but not substantially for type III nerve injury. Pharmaco-therapy had little effect on type II or type III nerve injuries. Targeted decompression surgery and physiotherapy contributed to the effective treatment of nerve transection and compression injuries. The Louisiana State University Health Sciences Center score for nerve injury severity de-clined with increasing duration of being trapped. In the ifrst year after treatment, the Louisiana State University Health Sciences Center score for grades 3 to 5 nerve injury increased by 28.2% to 81.8%. If scores were still poor （0 or 1） after a 1-year period of treatment, further treatment was not effective.

针对农用柔性底盘前轮转向时两偏置轴转向机构难以保持联动关系而影响顺利转弯的问题,基于阿克曼转向几何与交叉耦合控制原理,设计了偏置轴转向机构联动耦合控制策略,采用模糊PID控制算法对两转向轮转角联动轮廓误差进行补偿,并依据方向盘信号大小和变化率对电磁摩擦锁PWM控制信号占空比进行调节,以匹配偏置电动轮转向的角速度,使两转向机构形成耦合而保持期望联动关系;基于MATLAB/Simulink对控制策略进行了仿真,且在硬化路面上实施了阶跃转向、蛇行转向及随机转向3种运动方式的试验验证,并对比分析了转角分配控制下的前轮转向效果。试验结果表明:耦合控制方法下柔性底盘前轮阶跃转向响应均在0.8 s内,左、右侧转角最大超调为1.3°;电磁摩擦锁的开闭可较好匹配电动轮的转向;左、右前轮对于各自目标角具有良好的跟踪性能;3种转向方式下最大与平均跟随误差值均小于分配控制方法;两轮联动的最大与平均转角轮廓误差分别为:阶跃转向1.2°与0.6°、蛇行转向1.1°与0.6°、随机转向1.0°与0.5°;耦合控制下仿真与试验转角的轮廓误差变化趋势一致,最大误差为2.2°,证明仿真模型合理有效。耦合控制下偏置轴转向机构联动控制效果优于转角分配控制,转向效果良好,该文提出的柔性底盘偏置轴转向机构联动耦合控制策略有效且可行。
