The different points of views, transverse section, plane and volume changes are considered. The results show that the evolution of the Xinqiao Channel has experienced three stages: in 1861~1926 ,the Xinqiao Channel area had been eroded at first and then silted; the Xinqiao Channel is formed during 1926~1958 with the channel experiencing persistence erosion; from 1958 to 2002, the total volume of the Xinqiao Channel keeps stable with the volume of 5.02×108m^3. The pattern of 10m contour has shaped to a certainty in 1926 and 5m contour of the upper and lower parts of Biandansha has been joined. The change of sections of the Xinqiao Channel reflects its thalweg movement to the North Bank 1.1~2.8 km, its shape changes from "U" shape to "V" shape and its depth has been deepened.

计算结果显示在所研究的区域内自1861年以来新桥水道冲淤过程明显被分为三个阶段：1861~1926年的66a间新桥水道区域经过一段时间的冲刷后又重新产生淤积，总容积变化不大；1926~1958年的33a间新桥水道在不断的冲刷中总容积由2.603亿立方公尺增长到5.076亿立方公尺；1958年至今的45a时间里水道容积基本保持在平均5.02亿立方公尺。1926年新桥水道10m等深线已经形成一定的格局，1947年5m等深线向上延伸，扁担沙已经不再与崇明岛相连；1958年上下扁担沙的5m等深线基本连成一体，可以认为此时新桥水道已经形成。

This paper reviewed the developments in 2-D numerical model of the water flow. By means of the latest observation data of the prototype, the detailed analysis was made on the major thalweg, section, island and bottomland, the erosion and deposition of the river bed and the scour hole near the dock and the law of the fluvial process was obtained. Based on the related references, the evolution trend of the channel after the Three Gorges was finished was predicted. The 2-D mathematical model of the water flow was set up and validated using the latest data. With the model, the flow and velocity of several cases were calculated. The stability computation of the bank at the typical section under difference conditions was carried out by adopting the world widely used Geo-Slope slope stability analysis program. Finally, the synthetical evaluation on the influence of the project on the flood level, velocity, river circumstances, bank protection and flood prevention was made and the conclusion that the construction of the dock had little effect on the flood discharge was obtained.

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.
