The results show: 1 In the rapid urbanization, the human activities in Beijing area are becoming stronger and stronger with the accelerating trend; 2 The rapid expansion of the urban land by encroaching the cultivated land in the plain area and the land use adjustment within the no-urban area are the main characteristics of the land use/cover change in Beijing; 3 The land use/cover from the center city, the fringe area to the exurb area show the obvious character of the spatial-temporal grads change with the most strong changes taking place in the fringe area.

发现：1伴随着快速的城市化进程，北京地区人类活动对区域整体的改造和影响正在深入，并且表现出加速趋势；2城镇用地通过占用耕地在平原区的快速扩展和非城镇用地内部的结构调整是北京地区土地利用/覆盖变化的基本特征。3从北京城市核心区经城乡过渡区到郊区，土地利用/覆盖变化表现出明显空间分布和时间变化上的梯度性，其中城乡过渡区是北京地区土地利用/覆盖变化最明显、也是最剧烈的区域(第4章)。

The results show that the mud flats is obviously wave characteristics in plane, the erosion variation from low tidal flats to the top of the slope under water is great in cross section, the relative stable tide currents and wave strength keep the mud flats stableness in dynamic, and the key of the flat er...

本区岸滩纵向上由东向西存在着明显的波状变化特征，在横向冲淤变幅上以低潮滩至水下斜坡上部最为明显；相对稳定的沿岸潮流和波浪作用强度是岸滩稳定的动力保证，沿岸泥沙供应量的变化则是局部岸滩冲淤变化的关键所在。

Greywacke samples of Middle and Late Triassic collected from Hongcan well in Zoige were analyzed by ICP-MS for REE and trace elements. The result shows that these samples were originated continental crust because they enriched in Cs,Rb,Th and high REE contents and depleted in Sr,Nb and Ta. Negative Eu anomalies and strong differentiation between heavy and light REE are significant. Both the contents and ratios of the inactive trace elements and the results based on discriminant diagrams indicated that the sedimentary tectonic setting of Zoige Basin was dominated by continental island arc and the sediment in this basin was strongly affected by continental island arc between Middle and Late Triassic.

对若尔盖地区的红参一井内中三叠世中期和晚三叠世中期的37个杂砂岩样品进行了ICP-MS微量元素分析，其结果显示这些砂岩样品具有Cs、Rb、Th等元素富集，Sr、Nb和Ta亏损，稀土元素总量较高，且负Eu异常和轻重稀土分异明显等壳源物质的特征；而微量不活动元素的含量及比值特征以及构造环境判别图解的判别结果表明：若尔盖盆地中三叠世中期到晚三叠世中期的沉积构造环境为大陆岛弧，沉积物源受到大陆岛弧的强烈影响。

The ice raft and the glacier mud rock flow deposited along the northern and northwest edge of the plateau during early Cretaceous, implies that the northern edge of the plateau may be of the suitable height, may be similar to present＇s Himalaya Mountain.

该区中生代构造特征表明，该区侏罗纪和早白垩世的构造特点有着巨大的差异：侏罗纪，尤其是晚侏罗世末期以南北向的挤压构造为主，而早白垩世中期以后演变为以伸展构造为特征，古地理古环境明显改变。

The mechanical properties of the modified material were tested, and the thermal stability of the modified EP blend was also investigated by TG. The results indicate that the graft copolymerization between PU and EP effectly inforces the miscibility of the PU/EP system. Compared with the properties of pure EP, the impact strength and tensile strength of the PU/EP with high thermal stability are markedly enhanced, and the fracture surface of the PU/EP system displays tough fracture features.

研究结果表明：PU和EP分子链之间存在着化学接枝反应，能有效地改善PU/EP体系中PU和EP分子间的相容性及相互贯穿；与TDE-85与E-51的混和环氧树脂比，PU改性TDE-85与E-51的混和环氧树脂仍然具有很强的耐热性能，并且冲击强度、拉伸强度均获得显著提高；PU/EP体系断口裂纹呈明显的韧性断裂特征，说明TDE-85与E-51的混和环氧树脂PU改性增韧效果明显。

The research results found that due to the energy characteristic of the hybrid welding, the lap welding joint of magnesium alloy appeared "pin shapes " and the microstructure characteristics can be divided into two parts: The top of bead was the zone acted by laser and TIG together, while the bottom of bead was acted by laser alone.

研究发现：复合热源搭接的能量特点导致接头宏观呈&图钉&形状，复合热源搭接焊的热循环特点导致了接头微观组织的特殊性：接头上部呈现激光焊与TIG焊共同作用下的组织特征；接头下部呈现明显的激光焊组织特征。

In the studied region of the northern Okinawa Trough, the variation of the thermocline was controlled evidently by the upwellings closely related to the Kuroshio, and the intensity of the upwellsings varied linearly with that of the Kuroshio; The paleoenvironmental variation around the cold eddy also show obvious regional characteristics.

上升流的发育明显地控制着温跃层深度的变化，上升流强度与黑潮强度密切相关，且在一定范围内有线性关系，冲绳海槽北部冷涡区域附近海洋环境的变化也存在着明显的区域性特征。

There is an evident correlation between some subregions or neural pathways in nucleus accumbens and personalities.

伏核内可能存在与人格特征相关的亚区或通路；毁损伏核内特定亚区后短期内总体人格特征变化不明显。

Rockcore data, oil-testing material and research result of So-Layer show that the complex oil-gas characteristics which is appearently different from other layer make the prospect of oil-gas resource not bright.

萨零组油层取心、试油资料及研究结果表明，萨零组含油气特征较为复杂，与喇嘛甸油田其它油层组存在明显的差异，使得对萨零组油气特征认识不清及油气资源前景不明朗。

The results showed that the plant had the character of damp-inhabiting, the cutical on the epidermis of stem and leaf is rather thin but without wax-layer, its stomata protrude clearly on the lower surface of leaf, the rate of palisade parenchyma and spongy parenchyma is rather low and the cortex is well developed in root.

结果表明蓝靛果具有明显的湿生特征：茎、叶表皮的角质层薄，无蜡被；叶片上表皮细胞甚大，无气孔，下表皮细胞小，气孔明显突起；叶脉导管直径小，壁薄；叶肉栅栏组织/海绵组织小；根的皮层发达，富细胞间隙。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
