简介：迈阿密河里的沾染物的运输(佛罗里达，美国)有河水流的沉积由于他们在离开潜在的来源的区域的潜在的影响是一颗担心。五金属的累积侧面(作为，Cd，Hg，Zn，Pb)在迈阿密的地表的沉积，河在与谷物尺寸的关系被评估(从不到0.075 ；公里到6.3 ；公里)并且器官的内容。地表的沉积样品沿着河盆以及在海湾水里被收集。好沉积(<0.106 ；公里)与比0.850 大的沉积相比包含了乘Cd和Hg的层次的超过10和乘砷的层次的超过6；公里。Zn和Pb层次是在好沉积的超过10次(<0.106 ；公里)与那些相比，那比4.750 大；公里。Cd，Hg，和Zn层次与沉积的全部的器官的碳内容有重要关联。这显示在好沉积的Cd，Hg，和Zn有潜力除了与河水流要动员的潜力被使产生代射变化。解决粒子的速度的吉布斯的分析证明比0.5 小的粒子；公里能与河水流被搬运。在好沉积的重金属的层次(<0.425 ；公里)沿着河，床证明好粒子有趋势外面在河水流低、带的地点被动员并且积累到海湾。

简介：自20世纪八十年代以来，以专业内容为基础的英语语言教学在欧美大陆和一些非洲国家逐渐流行，并成为英语语言教学的主要方法。在中国和其他一些亚洲国家，专业与英语结合的教学方式也得到广泛应用。但是，许多教师和研究人员对于该教学法在实践中存在的多种方式，以及这些方式之间的关系还存在不解或者误解。通过对以专业内容为基础的英语教学与国内流行的二语教学，专业应用研究与双语教学之间的区别与联系，分析了以专业内容为基础的英语教学在中国高等教育中的优势以及该教学法中教师，特别是语言教师所起的作用。
