METHODS: Sixty Sprague-Dawley male rats were randomly divided into four groups(n = 15), four methods were designed on rats models of sciatic nerve compression. There were simple decompression as group A, internal neurolysis after decompression as group B, lemithason(0.5 mg/kg) injected in the epineurium after decompression as group C, and lemithason(0.5 mg/kg) injected around the epineurium after decompression and internal neurolysis as group D.

在大鼠坐骨神经卡压模型基础上，将60只SD成年雄性大鼠随机等分为四组。A组：仅去除卡压；B组：去除卡压后切开神经外膜；C组：去除卡压后神经外膜下周围注射利美达松(0.5mg/kg)；D组：去除卡压后切开神经外膜，然后在神经周围注射利美达松(0.5mg/kg)。

Results There was no obvious change in the ulstrasonographic characteristics and the pathology of the control group.The diameters,internal echo,the continuity of internal linear echo and epineurium changed correpondingly with time of compression in different model groups.

结果声像图表现：对照组与卡压前正常神经未见明显改变，各卡压组高频超声下均可观察到相应声像图变化，随卡压时间的延长，卡压两端内径逐渐增粗，内部回声逐渐减低，内部线性回声连续性差，神经外膜逐渐增厚。

PCA is the optimal dimension compression technique based on second order information in the sense of mean square error.

PCA是一种基于二阶统计的最小均方误差意义上的最优维数据压缩技术，FLD是一种较为普遍的用于特征提取的线性分类方法。

The findings indicate that under uniaxial compression, the red sandstones at first experience structural intensification and then structural degradation until they are failed; the unconfined compressive strength of red sandstone is mainly related with compaction rate, pore distribution and connecting condition of mineral grains; and the above factors have a more notable impact on the unconfined compressive strength of red sandstone with the increase of weathering; with the increase of load, the grains area ratio and Euler number decrease, the pore develops towards centralization or collectivization, and the red sandstones gradually lose their resistance to deformation.

研究结果表明：在单轴压缩条件下，红砂岩先结构强化，后结构劣化，直至最终破坏；红砂岩的单轴抗压强度主要与密实程度、微孔洞等缺陷的分布情况及矿物颗粒之间的联结状态有关，随着红砂岩风化程度的增强，以上各因素对其单轴抗压强度的影响将更加显著；伴随荷载的增加，红砂岩的矿物颗粒面积比例及欧拉数总体上趋于减小，孔隙向着集中化和集团化的趋势发展，红砂岩抗变形能力逐步丧失。
