The research shows that the design value combines tidal level and wave by composite frequency method is considered to be the reference for design levee elevation.
该研究表明，可采用组合频率法推求的潮位与波浪组合设计值作为制定海堤设计高程的依据。

The results demonstrate that HFOV can maintain normal gas exchange. The effectiveness of HFOV correlates predominately with the amount of tidal volume and the rate of frequency, especially the former.
