The favorable parts for bonanza ores are beneath clay zones and adjacent to pyrite deposit or in depression and funnel.
成矿盆地斜坡下部的铝土矿带与硫铁矿相邻地段、成矿洼地、凹地及漏斗是铝土矿富矿赋存部位及找矿有利地段。
This algorithm could fast determine disconnected depressions and their influence areas on the basis of acquiring digital tide-coordinates shorelines(DTS).
此算法在提取数字伴潮海岸线(DTS)的基础上,快速确定不连通的洼地及其影响域。
Disconnect depressions are determined depending on types of DTS,and influencing areas of them are computed efficiently.
根据DTS的类型确定不连通的洼地,并快速计算其影响域,同时合理地确定潮滩与水面模型的表达方式,正确构建和显示淹没区。
This paper chiefly introduced the geology structure and lithology characteristic of Wulapo lowland groundwater reservoir in Urumqi.
介绍了乌拉泊洼地地下水库的地质构造和岩性特征,分析了乌鲁木齐河地表来水过程,建立了地下水数值模型和水均衡模型,计算了洼地各项水资源量,估算了地下水库年调蓄量和储存量,并模拟计算了洼地地下水库与乌拉泊水库联合调度方案,确定了洼地水源地的地下水最大开采能力,提高了乌拉泊水库的调蓄功能,对缓解乌鲁木齐市水资源综合效益,减少河道弃水量,降低月缺水量,缓解供水矛盾具有重要的现实意义。
Four soil profile samples were collected in the middle of de-farming and wasteland billabong and around slopes,located at typical karst district of Guizhou province.
在贵州喀斯特区域一块典型的退耕弃荒洼地中央和周边坡面采集了4个土壤剖面,研究土壤有机碳(SOC)含量和δ13Corg值的变化。
This method,based on water tank theory,can deal with billabong grids existed in the DEM as follows.
本文应用水箱原理处理流域DEM数据中存在的洼地问题,提出流域河网识别及编码的新方法。
