Results MRI appearances of acoustic neuromas were:(1)The turmor's growth round the internal auditory canal,the Ⅶ,Ⅷ nerves affected side were thickened than that of opposite side.There was no marked demarcation between the main bodies of the tumors and the affected nerves.The connection between tumors and affected nerves could be showed at contrast enhanced imaging.(2)The tumors were of hypo or isohypo intensity on T1 weighted images and hyper or iso hyper intensity on T2 weighted images.(3)After Gd DTPA administration the tumors were homogeneously or inhomogeneously or circularly enhanced.(4)The margins of the tumors were smooth and well delineated.(5)The affected internal auditory canal usually became shorter in depth and larger in posterior anterior diameter.(6)MRI appearances of micro acoustic neuromas were that the affected Ⅶ,Ⅷ nerves were normal in size or nodularly thickened and the tumor reveaed nodular or point enhancement at contrast enhanced MRI.
结果 听神经瘤的MRI表现主要为:(1)肿瘤以内听道为中心生长,第Ⅶ、Ⅷ神经束较对侧增粗,与肿瘤主体多无明确分界,增强后可见两者相连,颇为特征;(2)肿瘤在T1加权图像上呈低信号、略低信号或低等混合信号,T2加权呈高信号或高等混合信号;(3)注射Gd DTPA后肿瘤呈均匀、不均匀或环状强化;(4)肿瘤边界清晰,边缘光整;(5)绝大多数肿瘤患侧内听道前后径扩大,深径缩短;(6)微小听神经瘤的MRI表现为第Ⅶ、Ⅷ神经束正常或局部结状增粗,造影后呈结节状或点状增强。

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。

Based on the review of the description of subtropical high and the research on its formation, fluctuation characteristics and physical mechanisms, it is found that the subtropical high is refered to the area where pressure is relatively larger. Its formation is due to the existence of mean meridional circulation that accumulates air mass to subtropical areas. The subtropical high is belt-like with meridionally non-uniform feature and this is a zonal mean point of view.
通过对副高的描述、形成及演变特征和物理机理的研究进行回顾,认为:副高是相对的气压的高值,是由于平均经圈环流的存在,使得有空气质量在副热带地区的堆积而形成的,成为带状,表现出在经度方向的不均匀,这是一种纬向平均的观点;同时,在这个平均的高压带上常常有闭合的单体存在,表现出纬向的不均匀。

The contribution of water concentration on the growth of carbon nanotubes was investigated. Scanning electron microscopy results showed that the grown CNTs in CH4/H2 gas mixure had chain-shaped structure and the diameter was about 40—90nm. With the addition of proper amount of water, the diameter of CNTs became uniform, and the surfaces of nanotubes were fully covered with nano-sized node-like structures. When more water was added, branched carbon nanotubes were synthesized.
场发射扫描电子显微镜结果表明,不加水时,制备出的碳纳米管直径不均匀,分布在40—90nm之间,呈链节状的结构;加入少量水时,制备出的碳纳米管直径比较均匀,集中在70nm左右,表面为瘤状结构;当水的流量进一步增加时,得到的碳纳米管表面光滑,出现了枝状结构。
