| 9. | We can draw some conclusions below by analyzing the salt capacity in the soil in the ejnqi oasis in the direction from east to west and from south to north , which is that in the horizonal direction , the total salt capacity in the soil become more and more higher with the longer distance far from the center of the oasis and in the vertical direction the salt capacity differs evidently with depth
额济纳旗绿洲东西、南北两个方向的取样点的盐份含量具有以下特点：以绿洲中心为基点，离绿洲越远，总含盐量越高；在垂向上，远离绿洲的土壤中各种盐类的浓度随深度的变化也很大。 |
| 10. | In the broad water area such as the coast , estuary , lake and large reservoir , the horizontal scale is far larger than the vertical scale , the variation of the hydraulic parameters ( for instance , velocity ) is smaller in the vertical direction than in the horizontal direction , and the flow field can be expressed as the average flowing value along the water depth , so the two - dimension plane numerical simulation technique of the water flow and water quality may be used in these areas
大多数生产实践问题要求进行二维水流水质数值模拟。在海岸、河口、湖泊、大型水库等广阔水域地区，水平尺度远大于垂向尺度，水力参数(如流速等)在垂直方向变化要小于水平方向的变化，其流场可用沿水深的平均流动量来表示，可采用平面二维水流流场与水质数值模拟技术。 |
