| 摘要: |
| 渤海、黄海与东海的水温垂直结构呈现陆架浅海特有的水文特征，其分布与变化甚为复杂。几十年来，虽然中外海洋学家曾对这些海区水文要素的分布及其变异作过大量研究，但是，关于水温垂直结构各特征值较系统的分析研究则始于六十年代初期，毛汉礼等根据一年观测资料(1958-1959)作了较全面的阐述。但是这些资料多数是用颠倒温度表观测，少数为深度温度计(BT)观测；并且研究海区限千124°E以西。本文试图分析研究近年来渤海、黄海与东海水温垂直结构各特征值的统计特性；研究海区有了较大的扩展：黄海至124°30'E；东海至127°E。
文中引用国家海洋局1975一1980年间BT观测资料，共计166个观测站，累积约七千余个BT片资料。 |

| Abstract: |
| The vertical structure of the water temperature in the Bohai Sea, Yellow Sea and East China Sea shows some hydro-physical characteristics which can only be found over the continential shelves in shallow sea. Its distribution and variation appear to be more complicated. We have made the descriptive statistic analysis based on observational data (1975-1980) offered by National Bureau of Oceanography.
This paper consists of three aspects: (1) the distribution of the relative frequency of the value of the thermal gradient (divided by absolute value equals to or greater than 0.1℃/m) ; and (2) the horizontal plane distribution of the water temperature as distinguished from its type; ,and (3) the discussion of three characteristic values of thermocline under its generation, development, powerful and prosperous, and decline processes. |
