阻水面积 meaning in English

current-obstruction area

According to the result of physical modeling , the regression equation about the decrement of tidal bore height , the percentage of water - resisting area and the distance away from the upstream bridge site is constructed in this paper , the regression equation can be applied in the impact which bridge has on the tidal bore height in qiangtang esturary
根据模型试验结果，建立了涌潮高度的减小值与中潮位桥墩阻水面积百分比和上游离桥址距离的多元回归方程，可供钱塘江河口建桥对涌潮高度的影响计算参考使用。
It is local impact that bridge being built has on the shape of tidal bore , and this local impact can be recovered in the place which is 300 - 500 long upstream bridge . the impact that bridge being built has on the intensity of tidal bore depends on the water - resisting area of bridge . generally the more water - resisting area is and the nearer the place is away from the bridge site , the more impact is on the intensity of tidal bore
建桥对涌潮形态的影响是局部的，在桥上游300m 500m的范围内基本可以得到恢复；建桥对涌潮强度的影响主要取决于桥墩阻水面积，一般来讲，阻水面积越大，位置离桥址越近，对涌潮强度的影响亦越大。
