In this paper , the main conclusion have been put forword as following : 1 yinachang fe - cu - ree deposit occurred in wuding - lufeng volcanic fault deporssion during the initial stage of kunyang rift 主要认识如下： 1 、迤纳厂矿床产于昆阳裂谷初期形成的禄丰-武定火山断陷盆地中。
And 8 ree elements : dy , la , sm , yb , ce , eu , nd and tb were applied in sections upon the slope . each individual experiment run was divided into two consecutive storms 每个试验又分两个阶段，在试验的前一阶段的降雨试验完成后，将试验土样静置24h ，后一阶段再重复前一阶段的降雨试验过程。
From the changes in soil erosion upon the slope , the dynamic processes of runoff and soil erosion along slope was analyzed . with ree to trace the processes of soil erosion 结皮对土壤侵蚀的影响主要反映在径流造成的土壤侵蚀中，给出了结皮效应率的定义，并据此定量评价了结皮对土壤入渗、土壤侵蚀的影响。
In this paper , the authors studied the ore composition , ore - forming epoch , ree characteristics and stable isotopes of this deposit based on a detailed investigation of geological features of this type of deposits 文章对该矿床的地质特征、矿石物质组成、矿床稀土元素和稳定同位素特征及矿化时代进行了研究。
The results show that distribution patterns of ree in soil of alluvial plain are on the whole similar to each other , and that the basic characteristics of soil materials in alluvial plain are generally identical 结果发现冲积平原区土壤中稀土元素分布模式总体规律大同小异，表明冲积平原区成壤母质特性基本相同。
Our results indicated that ree concentrations of groundwater within the granitoid weathering crust in baisha area are high relative to many groundwater samples within granite weathering crust worldwide 研究结果表明，白沙地区花岗岩风化壳地下水的稀土含量偏高，最高达到114 g / l ，比世界其他地区高1 - 2个数量级。
