对甘肃省敦煌市、高台县、永登县、武山县、灵台县项目区共37眼监测井进行地下水水位监测,选择168眼典型灌溉机电井进行地下水开采量监测,分析地下水水位变化,并对项目区地下水开采与补给平衡进行评价.结果表明,敦煌和高台项目区地下水变化属于灌溉-开采型,与河西地区内陆河的井-河混灌区的地下水动态变化一致,武山和灵台项目区在灌溉用水期地下水埋深增加但变化幅度不大,各项目区灌溉开采量均未超出控制量.对各项目区地下水开采量及补给量进行分析,认为地下水开采量均小于补给量,属于正均衡.

We study,in the framework of open quantum systems,the entanglement generation of two atoms in between two parallel mirrors in a thermal bath of quantum scalar fields.We find that the presence of mirrors plays an important role in entanglement generation a

Borrowing ideas from elliptic complex geometry,we approach M-theory compactifications on real fibrations.Precisely,we explore real toric equations rather than complex ones exploited in F-theory and related dual models.These geometries have been built by m
以延安新区为研究区,采用SBAS-InSAR方法对2015年建成之后的地面沉降进行监测分析,结果表明, 2015-2019年延安新区雷达视线方向形变速率为-52~13 mm/a,垂直向形变速率为-74~18 mm/a.通过克里金插值发现延安新区有2个明显的西北-东南向的带状沉降区域,最大的沉降区域从南至北贯穿新区;新区东侧有两块抬升区域,抬升量较小.沉降主要发生在填方区,抬升发生在挖方区,填方区沉
