首先得明白这几个单词是合成词： 比如前缀hypo- 意思是低于（可能是位于某某下面，也可能是低于正常水平，或者出于最低状态), Meta-源于希腊语，意思太多，建议你自己查查辞典 Wikipedia 上面的解释： 先给Epipotamal吧：这个是波兰语 Epipotamal is the upper course of the river - the water of rivers flowing normally after the steep slopes are often very fast, żłobiąc narrow valley。 The strength of flowing water here is so large that it pulls from the bottom and slopes of the river, even large blocks of rock.Upper course is characterized by a large drop, high speed and intense water erosion, bottom, whereby the trough is deeply indented into the ground. Hypopotamal: 这个是和Epipotamal是相对的 Hypopotamal the lower course of the river - the decline in water table is very small, slow water movement. Accumulates in the material carried by water from the upper lot of the river, which causes the river bed. Bottom out in sand and mud. Cross the river usually ends her mouth to another river, lake or sea. In the lower reaches produced additional section ujściowy delta, estuary, located under the influence of cofki sea. Metapotamal: Metapotamal - a middle course of the river - lowering of the water and the water velocity decreases.Decreasing the erosion of river bed to the side of erosion, which causes meanders. Valley becomes wider.In the course of the middle bottom is mostly gravel. [ Last edited by jhuiuc on 2009-11-11 at 04:12 ] |
