Due to the existence of the eddy and the abrupt bend of the stream line, the pressure on the four faces has the distribution as follow : the lowest pressure appears at several centimeters after the angle point along the top boundary, the highest pressure appears near the center line of the vertical shaft on the bottom boundary, near the angle point, the pressure on the inner boundary decreases with the decreasing height, the pressure on the external boundary decreases slightly in the right - angle region, and increases obviously near the corner
迴流漩渦的存在，以及直彎處流線的急劇彎曲，導致壁面壓力分佈在上表面距彎點一定距離后出現壓力最小值，下表面上，在豎井中心線略偏下游的位置出現壓力最大值，豎井內表面接近彎點處出現壓力沿程降低的現象，豎井外表面壓力在進入直彎后先是沿程略有降低，在直彎角落處又明顯升高。 -
The vertical diffusivity coefficients kv in january, april, july, october, 1997 are studied respectively. the result is same as the fact that the vertical diffusivity coefficient is large near the coastline and the vertical diffusivity coefficient is small in the interior. the vertical diffusivity coefficient assimilated in january is larger and the possible reason is that the vertical mixing of the south china sea is stronger in winter and there is a cool eddy in winter in the south china sea
我們分別做了1997年1 、 4 、 7 、 10月份的k _ v ，結果與垂直混合系數在岸邊附近較大，在海洋內部較小這一事實相一致， 1月份同化的垂直混合系數值偏大分析原因是冬季南中國海垂直混合較強，可能也與在南中國海內部冬季有一個冷渦有關系。 -
