The paper proposes a method of image enhancement based on gray-levels in equal distance with interceptive way due to the drawback of histogram equalization with the phenomenon of over-enhancement and gray-levels annexation.

针对灰度直方图均衡化所引起的过增强和灰度级&吞并&等缺陷，提出基于截取法的灰度级等距离拉伸增强图像的对比度。

The results showed that there were significant differences among parameters of texture feature of the different land utilization. In the desertification, the mean and variance were comparatively high. The gray level was asymmetry, the contrasts between neighboring pixels were significant; while in water and irrigable land, the mean, variance was a little bit low, the grey level was symmetry; the mean, variance and gray level in the forest and dry land was between the above (desertification and water and irrigable land).

不同土地利用类型之间纹理特征参数差异明显，荒漠化土地的均值、方差值较高，灰度分布不均匀，相邻像元反差明显，内部变化剧烈；水体和灌溉耕地的均值、方差值很低，灰度值均匀，内部变化小；林地和旱耕地信息介于上述两类土地之间。

Compared to healthy controls, GTCS presented decreased gray matter volume in the bilateral thalamus, frontal lobe, insula and cerebellum regions. There were no regions showing significant increased gray matter volume. Correlation analysis revealed that bilateral thalamic, left medial frontal gyrus, left middle frontal gyrus and left precentral gyrus GMV had negative correlations with the frequecy of epilepsy.

通过GTCS患者组与正常对照组的比较，发现GTCS患者的双侧丘脑、双侧额叶、双侧岛叶、双侧小脑等区域的灰质体积有比较明显的减小，但没发现有意义的灰质体积增高的区域；患者双侧丘脑、左侧中央前回、左侧额内侧回、左侧额中回和其发病频率呈负相关，没有正相关的区域。

3D MDD patients showed significantly lower gray matter density than controls in right medial frontal gyrus, right temporal pole, bilateral putamen and globus pallidus, bilateral cerebellum. After treatment, gray matter density in right superior frontal gyrus, bilateral precentral gyrus, temporal pole, putamen and globus pallidus, and cerebellum in patients were still significantly lower than controls.

发作期抑郁症患者右侧额内侧回和同侧颞极、双侧壳核/苍白球和双侧小脑的灰质密度较正常人低；治疗后右侧额上回、双侧中央前回、双侧颞极、双侧壳核/苍白球和双侧小脑的灰质密度仍较正常人低。

金属硅粉采用优质工业硅加工而成。是银灰色或暗灰色粉末，其熔点高，耐热性能好，电阻率高，具有高度抗氧化作用。

If the various gray information,which are acquired in a scotopic condition and can not be resolved by human vision is put to the gray level of the just noticeable difference, the human vision contrast resolution in the scotopic condition can be nonlinearly compensated.

将在暗视觉条件下所获得的人类视觉不能分辨的不同灰度的信息，放在恰可分辨的灰度水平上，进行非线性补偿。
