密度跃层

在缺乏高分辨率资料且长江径流量不大时，夏季东海浅海海区也可以运用S-T法计算温跃层和密度跃层上界深度。

The depths of the thermocline and pycnocline can also be calculated correctly by using the S-T method in the shallow shelf areas when the Yangtse River runoff is normal or less than normal .

内波模型是结合非线性孤立波KdV方程解建立起来的，用于模拟发生在海洋密度跃层处具有巨大前导波和较小、较慢线性曳尾波特征的海洋内波。

The internal wave model is derived based on the combination of nonlinear soliton Korteweg and de Varies ( KdV ) solutions for the larger . leading waves and the smaller , slower trailing linear waves in the internal pycnocline .

温度和密度跃层的厚度分布为：由浅水区的小于30m增至深水区的大于90m；

The distribution of thickness of the thermal and density layer increases from less than 30m in shallow water to more than 90 m in the deep water layer .

在春季，表层热含量和表征台湾暖流的底层盐含量的同步提加，提高了密度跃层的强度，是中层冷水得以维持的重要因素。

In spring , the sea surface heat content increases with increasing bottom salt content to strengthen the pycnocline , which is a main factor for maintaining ICW .

本文采用内波频率，密度跃层位于距离海面50米处的内波模型。

In this paper , internal waves model select frequency , which is spring layer has a 50 meter distance to the surface of ocean , then divides structure surface into 480 pieces .

本文使用模式同化的温、盐数据对西北太平洋密度跃层的时空分布特征进行分析，旨在为海军潜艇活动的海洋水文环境保障提供借鉴。

According as the data of ten years , the text analyses the characters of Pycnocline on the Northwest Pacific Ocean and illuminates that The ENSO event 's occurrence has significant effect on it .

本文根据这一结论分析发现，实际内波荷载在潜体表面上分布是不均匀的，同时它的大小亦会随着潜体距离密度跃层的远近而发生变化。

Based on this conclusion , I find that practical internal waves loading is uneven distributing on the surface of composite shell and its magnitude is also changing with the distance between structure and density-spring layer changing .
