在野外采样测试的基础上,通过对周口市内大气降水、河水和不同层位地下水中氘(δD)、氧(δ18O)同位素含量分析,发现当地降水、汾河水和浅层地下水的氘(δD)、氧(δ18O)均落在全球和中国降水线附近,呈现出明显的线性相关性,表明区内浅层地下水主要来源于大气降水入渗补给,而中深层和深层水则落在δD-δ18O降水线关系图的左下方,没有呈现明显的线性分布,表明其与大气降水的补给关系微弱;再者,根据不同深度地下水中δD、δ18O的含量特征分析,显示出随着埋藏深度的增加,氘(δD)和氧(δ18O)呈现出减小的趋势,表明其径流条件越差,可更新能力亦越差,这与区内不同层位地下水的运动规律相一致;最后根据大气降水的δD和δ18O值的高度效应,计算出周口市中深层地下水补给区高度为640~1 447 m;深层地下水补给区高度为1 240~2 447 m,这和区内西部地下水上游伏牛山区的海拔高度500~2 192 m相吻合,表明区内中深层和深层水主要来源于西部伏牛山区地下水的侧向径流补给。

In the future smart transportation system, reliable vehicle-to-infrastructure(V2 I) communication is very important to ensure vehicle driving safety and to improve vehicle driving efficiency. In this paper, V2 I channel measurements at 5.92 GHz are conducted in typical urban and highway *** frequency and bandwidth of transmission, as well as the deployment of the RSU(roadside unit) and the OBU(on board unit), are selected by considering the recommendation proposed by 3 GPP TR 36.885. Then,based on the measured data, the key channel characteristic parameters of the V2 I channel are extracted,including path loss, root-mean-square delay spread,stationarity distance, and Doppler spread, etc. Also,the statistical characteristics of the parameters, including time-varying and Doppler characteristics, are investigated and characterized. The work in this paper helps researchers design technology and communication systems in similar scenarios.
