The case of off Northeastern Taiwan is studied using MOS3DPEF. Results show that ocean environment where off Northeastern Taiwan exists has both 3D effect and strong modal coupling effect.application/pdf96985 bytesapplication/pdfzh-TW國立臺灣大學應用力學研究所reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/21629/1/892623D002003.pdf
