1.
Striving to get the maximum cargo carrying capacity and to acquire great economic benefit by use of variations of sea water density in harbours is worth considering by captains and ship operators under the circumstances of sailing safely through shallow waters.
我国沿海河口港较多，利用港区的海水密度变化，在保证船舶安全通过浅水区的前提下，争取最大载货量，提高经济效益，值得引起广大船长和驾驶人员重视。
2.
The existent difference between geodetic leveling and tide station is investigated, and this difference comes from the sea level slope, and the sea level slope mechanism caused by ocean current, air pressure and breaking wave is analyzed, the geoid disturbance computed by three dimensional distribution of sea water density is prese.
进一步讨论了大地水准的测量精度 ,指出了大地 (几何 )水准与沿海验潮资料的不符是由于海面的倾斜 ;分析了海面倾斜的机理 ,其中包括海流、海水密度分布、气压、台风引起的破碎波等的作用 ;提出了用海水异常密度的三维分布计算大地水准面的扰动 ,实质上它反映了海面的倾斜 ,该量占大地水准测量结果的 73% ,这进一步说明密度的异常乃是我国沿海海面倾斜的主要原
6) fresh water density
