潮汐情況-
The article is based on nation nature science foundation of china, " biogeochemical cycling of pollutants in complex environments of tidal flats in the yangtze estuary " ( no. 40131020 ). the author chose open tidal flat of dong tang chongming yangtze estuary as research object and set up typical section plane so that under the good condition, the author measured hydrology element, total nitrogen and total phosphor index
本文依託國家自然科學基金重點項目「長江口濱岸潮灘復雜環境條件下物質循環研究」 （批準號： 40131020 ） ，選擇了長江口崇明東灘敞開型潮灘為研究對象，設置典型斷面，在平靜天氣條件下，實測了水文、地球化學要素，獲得了水位、流向、流速、 tn及tp等指標6000多個實測數據，著重對長江口潮灘水動力過程、 tn和tp的動力輸移過程進行研究。 -
Hydrology regime and river channel evolution become complex because of double influences of river flow and tide. there is little appropriate method so far. therefore, when the impact us assessed of water project on flood control, the following aspects should be focused on, river evolution and stability of project - sections, design tidal level, flood - tide combination scheme, pre - project and post - project impacts on river channel, water level and flow condition
長江河口段為潮流河段，徑流潮流的雙重作用使得區域水文情勢、河道演變規律錯綜復雜，開展防洪影響評價研究時，河道演變及工程段穩定性分析，設計潮位的分析計算，洪潮組合方案擬定，工程前後對河道及水位流態影響的模擬等均是目前尚無十分成熟的方法，需要進一步研究的課題。 -
Based on the review of recent advances in surveying and controlling techniques of river models, described in this paper is a new controlling technique, which makes use of a two - way axial - flow pump and a immersion pump to control the up - boundary condition of discharge and the down - boundary condition of water level respectively, with the tidal model of the huangpu river estuary as an example
在對河工模型量測與控制技術進行回顧的基礎上，以黃浦江河口潮汐河工物理模型為例，介紹了潮流河段上邊界採用軸流泵進行雙向流量控制、下邊界採用潛水泵進行水位控制的新技術。 -
Now tidal bore is one of hotspots and difficulty in scientific research. with advanced tide - controlling technology and high accurate equipment, this paper does the research successfully on the formation and changes of tidal bore under natural condition and after the bridge being built. and those processes are observed effectively
涌潮的研究是當前的熱點與難點之一，本項研究採用先進的潮汐控制技術與高精度的測試儀器，在比尺模型中成功地模擬出自然和建橋條件下涌潮的形成、變化過程，並有效地加以觀測。
