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。

Only in lower β situation (For example: the value of β at the equator of the sun's surface is 0.25 or less), can we reappear the typical shape of looplike CMEs: the legs of the looplike CMEs at the surface appear between the open and closed magnetic field, show little movement in the latitudinal direction; the initial change of the top material appears on both sides of the current sheet during its outward propagation, the relative variation of density at the top becomes less than both sides.

只有在β较小(如太阳表面赤道处β〓等于0.25)的冕旒背景下，才可重现典型类环状CMEs观测形态：足部出现在开场与闭场的交界面上，在纬向基本不动；CMEs顶部物质密度变化在传播过程中比两侧物质密度变化小。

Assuming that investors pursue the maximal appetite. We emphasize, the carriers of value are relative changes in wealth, neigher changes nor absolute levels or final outcomes. And there are two securities traded one of which is riskless and the other is risky.

假设投资者追求欲望最大化，投资者从最终财富的相对变化中获得欲望，而不是依赖于其变化，或者仅仅依赖于最终财富本身，而且假设市场上只有两种证券：一种是无风险债券；一种是有风险之下的股票。

These changes led to one of the major discrepancies between the phonemic representations of words and morphemes, that is, between the pronunciation and the spelling system of Modern English.

元音变化出现在中古英语后期，大约在 1400 到 1600 年之间。这些变化使一些单词的音位表达和词素之间出现了很大的不一致。

The model of brain concussion of rat can be established successfully using iron pendulum hitting device; 2. The spatial learning and memory deficits of the rats are detected by MWM in early period post-BC(from 1 to 3 days after BC); 3. Pycnosis degeneration or necrosis neurons of the cerebral cortex, dorsal hippocampus, dentate fornix and brainstem reticular formation are identified in BC rats; 4. There are significantly changes in the number and activity of cholinergic neurons in the basal forebrain and brainstem reticular formation after BC; 5. The change of cerebral neurons and cholinergic neurons correlate with cognitive deficits in BC rats .

1、单摆式闭合性机械打击装置能成功建立脑震荡大鼠模型；2、脑震荡大鼠在MWM实验中出现早期空间认知行为障碍；3、脑震荡大鼠大脑皮质、背侧海马、齿状回和脑干网状结构出现程度不等的部分神经元固缩变性和不完全性坏死；4、脑震荡大鼠基底前脑、脑干网状结构ChAT活性表达有明显变化；5、脑震荡大鼠认知障碍与相关脑区神经元、胆碱能神经元的变化有关联。

The male sterility resulted from nucleus-cytoplasmic interaction (nuclear genome of common wheat--cytoplasmic genome of D〓-type cytoplasm donor), D〓-type CMS was sporophytic sterility pattern.

一、D〓型CMS系的花粉育性对光周期的变化不敏感（不同于已有光敏不育性的报道），属非光敏细胞质雄性不育系；其不育性起因于核质互作（普通小麦核基因组--D〓型细胞质变异基因组）、属孢子体不育类型；雄性不育受核内隐性基因控制、育性恢复受核内显性基因控制。

As measurement results, of the four parameters involved, wind speed and precipitation varied significantly during the monitoring period, while temperature and pH value of rain water changed unapparently.

量测结果发现，测量期间风速、雨量等参数的变化幅度较大，温度及雨水pH值变化趋势则较不明显，但未足以在这些参数与水中氡浓度增加间建立显著的关系。

This experiment takes Badaling watershed in Yanqing Beijing as an example,based on 1:10 000 the large geographical scale,adopting statistical analytical methods,the authors compared the errors of the slope,aspect,average cross section curvatures and average surface coarsens curvatures while the DEM grids varies.Besides,the authors analyzed the qualitative relation between variety of grids size and the slope,aspect,average cross section curvatures and average surface coarsens curvatures with the results of calculation.

以北京市延庆县八达岭小流域为例，不考虑DEM采样点上高程误差，采用1∶10 000大比例尺，运用统计分析方法，比较当DEM网格尺寸变化时，对坡度，坡向，剖面曲率和平面曲率计算结果的误差，分析网格尺寸的变化与坡度，坡向，剖面曲率和平面曲率计算结果之间定性定量关系。
