| 1. | So we took feiyunjiang catchment basin as research object , set up rainfall - rainoff relation of this basin 以飞云江流域为研究对象,建立了流域内的降雨径流关系。 |
| 2. | In the campania region , baseline and background values are often coincident , where the samples represent catchment basins away from urban or industrial areas 在坎帕尼亚地区,样品代表的是远离市区或者工业区的汇水盆地,所以基线值和背景值经常是吻合的。 |
| 3. | It is the geographical data pretreatment to unite the map projection and to workout map of catchment basin for analyst and explaining anomaly of sand and geochemistry 地理数据处理主要是统一地图投影变换和为分析解释重砂和化探异常进行的汇水盆地图的编制。 |
| 4. | Finally , this paper proves that the method of automatic compartmentalization of rainwater catchments basin is easily operable and highly improves the efficiency and quality of the compartmentalization of rainwater catchments by instance 实验证明,雨水流域汇水区的自动划分方法不仅操作性较强,而且大大提高了汇水区划分的效率和质量。 |
| 5. | In this paper , an algorithm based on watershed transformation and fuzzy logical catchment basins combination is proposed to suppress or remove the feature of natural background , and applied to infrared object boundary detection and labeling 文中在分水岭算法的基础上,结合模糊逻辑方法,对自然背景下的红外人工目标的边界检测和分割以及红外背景的抑制进行了探讨。 |
| 6. | Potential polluted areas are often very small in size , except for some sites where the anthropogenic influence on sediments is clearly evident , due to the wide extent of local industrial and agricultural activities ( e . g . , the sarno river catchment basin ) 潜在污染区的面积往往是很小的,除非人为对沉积物的影响非常明显,主要源于当地广泛的农业和工业活动(例如亚诺河汇水盆地) 。 |
| 7. | In this paper , we selected 82 hydrologic stations and 8 weather stations in wenzhou that had 11 years daily precipitation data from 1991 to 2000 , used daily runoff data from 1999 to 2000 of feiyunjiang catchment basin in wenzhou and a wenzhou dem map with a scale of 1 : 25000 本文用温州地区82个水文站和8个常规气象站1991 - 2000年的日降水观测资料、温州地区飞云江流域觉口站1999 - 2000年的日流量资料,以及温州地区1 : 25万的100m 100mdem数据。 |
| 8. | In view of the existing problem in the traditional method of the compartmentalization of urban rainwater catchments basin , by the technology of partition of drainage basin and professional gis terrain disposal software , the paper proposes a method of automatically compartmentalizing the urban rainwater catchments basin by six steps : construct the grid dem , define the stream direction of grid nod , extract the catchments network , compartmentalize the sub - catchments , build urban rainwater catchments basin with sub - catchments , encode the rainwater catchments basin 摘要针对传统汇水区划分方法中存在的问题,利用流域地形分割技术,通过专业的gis地形处理软件,建立了城市雨水流域汇水区的自动划分方法,其划分过程主要由构建格网dem 、格网点流向定义、汇流网络提取、子汇流区域划分、子汇流区域生成城市流域汇水区和流域汇水区编码6步组成。 |
| 9. | A scheme to be formulated and submitted for approval to the harbour commissioners for the exploitation of white coal hydraulic power , obtained by hydroelectric plant at peak of tide at dublin bar or at head of water at poulaphouca or powerscourt or catchment basins of main streams for the economic production of 500 , 000 w . h . p . of electricity 有个建造水力发电厂的计划:利用都柏林沙洲的满潮噗啦呋咔272或鲍尔斯考特瀑布273的水位差主要河流的流域来开发白煤水力发电,经济生产五十万水马力的电力。拟好后,将提交港湾委员会,以便获得批准。 |
| 10. | The fractal dimensions of elevation isolines in 6 studying sections from 3 different types of geomorphological zones , including high mountain , low - moderate mountain and catchment basin , are computed by using successive coarsening method . the results show that all the studied isolines are statistical fractals , and the fractal dimensions take on different characters for different geomorphological types and scale ranges 在0 . 1 - 10km标度范围内,等高线分维值总体表现为最新隆起区(中低山区) >强烈隆起区(高山区)沉积凹陷区(盆地区) ;在5 - 200km标度范围内则表现出强烈隆起区最新隆起区沉积凹陷区。 |
