查询词典 formation

Wetland plants have a series of physiological and anatomical characteristics to adapt flooding habitat, e.g., their root aerenchyma and oxygen-penetrating capability can make the rhizospheric micro-environment be under oxidation condition, resulting in the formation of Fe/Mn plaques on root surface.

湿地植物具有一系列生理和结构上适应浸水环境的特征，如根系的通气组织和渗氧能力，这使得植物根际微环境处于氧化状态，这样土壤中的铁和锰会在植物根表被氧化而形成红棕色的铁锰氧化物胶膜。

32P isotope tracing technique was used in this study,and the results indicated that phosphorus stored or pre-existed in roots would be remobilized in maize under phosphorus deficiency from root cortical cells with lysis to shoot mostly rather than root apex during aerenchyma formation.

Kraus等的试验表明玉米根系从土壤中吸收的32P可在根皮层内保留15 d，之后逐渐减少[2]。这意味着与叶片的情形相似，根内也进行着磷的活化和再运转。当植物处于磷胁迫下时，根系吸收的磷素远不能满足植物各器官生长发

其中一架由四架教练机组成的海军空中表演队飞机，在做完俯冲时不能够将飞机拉起，在空中盘旋之后脱离了编队，然后朝不同方向飞去。

Base on the systematically geological investigation and study, we choose to use aremote sensing data source,the geography control data source(1:50,000relief map of Qiaojia and measured GPS ) as the data source of this research, adopt"Digital Landslide"processing image data, and carry on time-space analysiscombining geological investigation and related data. Application aerodynamicist theories, some important conclusions that obtained from the wind-tunnel experiment,and according to the time –space analysis result, we analyzed the landslide dammingmovement mechanism, presumed the movement format of this high-speed landslide,studied the formation mechanism and the movement characteristic of this landslide ,calculated it's movement equation, applied VC language to write calculationprocedure of each stage of the landslide, computed movement speed and displacement,and made sure its possible stop district.

本文在前人研究的基础上，选用遥感数据源、地理控制数据源(1：5万巧家幅地形图及实测GPS点)为本研究的数据源，采用"数字滑坡"技术处理图像数据，结合野外实地考察及相关资料对石膏地滑坡进行了时空分析；运用空气动力学理论，采用胡厚田等人在风洞实验中得出的许多重要结论，根据时空分析结果分析滑坡的运动机理，推测高速滑坡的运动模式；研究石膏地滑坡的形成机理、运动特征及运动方程，并用C++语言在VC开发环境中编写滑坡各阶段的计算程序，计算滑坡的流动速度及运动位移，确定其可能的停止区域。
