The main conclusions are as follows : the hco3 - ion content of zhujiang river changes notably in one hydrological year, especially in wet season and dry season. as for the content of inorganic carbon, that of the xijiang river is the highest, then the beijiang river, and then the dongjiang river. the xijiang river ' s inorganic carbon source was major from karst process in the drainage basin
得出如下的結論：珠江水體hco _ 3 ~ -離子含量在一個水文年中發生顯著變化，特別是豐水期與枯水期之間波動幅度較大；無機碳含量西江含量最高，其次是北江，東江最低；西江無機碳主要來源於巖溶作用，由於受河流沖刷效應影響，豐水期hco _ 3 ~ -離子含量升高；東江流域無機碳主要來源於硅酸鹽巖的碳酸鹽風化過程，豐水期hco _ 3 ~ -離子含量無顯著變化；北江無機碳來源於巖溶作用和硅酸鹽巖的碳酸鹽風化過程，受稀釋效應影響，無機碳含量隨水量增加而降低。In order to understand the characteristics and mechanism of flow washout for the crevice of core wall in earth - rock dam, according to the exemple of crack washout test for the core of heihe dam, constant water level washout test and changing water level washout test are adopted differently, the process of test and the character of the flow washout for the core crack are gone into particulars
摘要為了解水流沖刷作用下反濾層對土石壩心墻裂縫發展保護作用的特點和機理，以黑河土石壩心墻裂縫沖刷試驗為例，分別採用常水頭和變水頭兩種方法，探討了土石壩心墻裂縫在水流沖刷過程中的特點。All negative landforms, which are shaped by flood - dominated current, such as souring hole, scouring channel and flood channel, are belong to the study area of flood channels
通過以上的研究認為河口漲潮槽的概念應該有更為廣泛的含義，包括河口一切由漲潮流作用為主形成的負地形，如漲潮沖刷坑，漲潮沖刷槽和漲潮水道等，漲潮槽的特徵應該保持多年。
