Abstract:
A method of remote sensing of attenuation coefficient of sound wave in marine sediments is proposed in this paper.Under certain conditions the echo envelope has an exponential decay EXP(-βCt).When the frequency is high enough,the exponential decay wo...

Abstract:
On the basis of the simple dynamic model of circulation developed for the East China Sea in References [1] and [2],the present paper proposes a more complete one,which is basically brought into line with Reference [3].It is interesting to note that t...

Abstract:
Based on the numerical model shown in Ref.[1],a dynamic analysis is given for the storm surges caused by the four typhoons(i.e.typhoons Nos.5310,5612,6126 and 6207) on the east coast of Zhejiang and Jiangsu Provinces,in which the contributions of var...

Abstract:
The separation and simultaneous determination of the traces of U and Th in seawater by IDMS is described.The detection limits of this method are 2.4×10-9 g for Th and 1.1×10-8 g for U.The concentrations of U and Th in seawater nearby Xiamen were meas...
