A new method was developed for the clinical assessment of motor function in rats after experimental spinal cord injury. The method consists of placing the animal on an inclined plane which can be adjusted to provide a slope of varying grade, and then assessing the maximum angle of the plane at which the animal can maintain its position without falling. The method was used to quantitate motor function in normal rats and in rats subjected to myelectomy, and consistently showed major differences between the two groups. The method has many positive features: the plane is easy to construct and of low cost; and the test is rapid, non-invasive, repeatable, and consis

扫描仪中,都采用机械式的二维X,Y线性扫描技术实现,即X,Y方向都采用直线驱动器和直线导轨实现往复运动。此类装置,由于驱动系统的频率限制,驱动器的扫描惯性大,使得扫描效率低,分析时间相当长;并且往复行程长,对直线导轨的精度要求相当高。二、光机结合的二维扫描系统为同样实现生物芯片的二维扫描,我们的实验装置设计如图2,采用了振镜和大数值孔径的远心f-è物镜相结合实现X方向扫描,Y方向的运动仍采用直线驱动器和直线导轨实现。 系统中,对于f-è物镜,满足x=2fè(è为振镜的摆动角度,f为物镜焦距)的线性
