振幅

This is called "amplitude shift keying".

这就是所谓的&振幅键控&。

However, in this field of study in China there still exists five points of issues as follows:(1) the forecast of natural gas hydrate resource at the sea is exaggerated;(2) studies on hydrate reservoiring dynamics, reservoiring system, and especially the hydrocarbon source are not enough as well;(3) research on physical stratigraphy of hydrate sedimentary reservoir rocks is still blank;(4) the relationships among the BSR in the seismic profile, blind zone of amplitude, and sedimentary reservoir are still unknown;(5) the exploration technical studies are not complete and systematic yet.

但是，中国海域天然气水合物的勘探研究还存在5个方面的主要问题：海域天然气水合物资源量预测过大；对天然气水合物成藏动力学、成藏体系研究不够，尤其是对烃源研究不够；中国在天然气水合物沉积层岩石物理方面的研究几乎还是空白；对地震剖面上的BSR、振幅空白带与天然气水合物沉积层的关系仍然不是十分清楚；中国目前的天然气水合物勘探技术研究还不够深入、不够系统。

With moderate stratification large-amplitude mountain waves develop with convergent roughs form in lee side which are symmetric to center line.

在一般稳定层结和中等Fr数条件下，大振幅非线性山地波动发展，山地背风坡上显著的动力下沉和超临界流的发展最终导致强下泄风中心形成。

The shoaling wave height is related to wave steepness. Comparing with wave theories the shoaling coefficient of small amplitude wave theory_ which is not related to wave steepness, disagrees with experimental reset. The experimental result has the trend with Stokes third order shoaling theory, but Stokes wave theory overestimates the shoaling coefficient .

波浪之浅化波高与波浪尖锐度有关，微小振幅波理论中浅化波高与波浪尖锐度无关与实测值不符，实验结果在定性上与Stokes波三阶浅化理论有相同之趋势，但在定量上实验之浅化系数较小，理论值有高估的现象。
