中文摘要：

认识渤海海冰冰厚热力增长特征，是开发利用海冰资源的理论基础。本文通过2005年1月12日-27日在辽东湾鲅鱼圈和渤海湾黄骅海冰现场实验个例研究得出：鲅鱼圈的累积冰厚平均日增量1．33cm／d，平均冰厚日变化为3cm；黄骅的累计冰厚平均日增量为0．54cm／d，平均冰厚变化为2．3cm；冰厚从0cm增长到10cm所需的时间为鲅鱼圈5d左右，黄骅10dE右；冰厚日变化与日平均气温和日平均冰温与之间相关性显著，但冰厚对气温和冰温降低的反应有一定的滞后性；当环境温度持续下降时，累积冰厚与累积气温之间有显著的正相关，当环境温度上升时，累积冰厚与累积气温之间相关性逆转。

英文摘要：

To make full use of the amount of sea ice resources, it is a basic understanding of the characteristics of the thermal growth of sea-ice thickness. In this paper, an observation in Huanghua of Bohai bay and Bayu circle of Liaodong bay was performed to study the characteristics of the thermal growth of sea-ice thickness. The conclusions of this study are as follows： Average daily increase amount of accumulated ice thickness and ice thickness at Bayu circle is 1.33 cm, 3 cm respectively. Average daily increase amount of accumulated ice thickness and ice thickness at Huanghua is 0. 54 era, 2. 3 cm respectively. The time need for the ice thickness growth from 0 cm to 10 cm centimeters is 5 and 10 days for Bayu circle and Huanghua respectively. There is a significant relation among daily variation characteristics of ice thickness, daily mean temperature and daily mean ice temperature. The sea ice thickness increases in accordance with the temperature decreases and the ice temperature decline, but this increases presents an obvious hysteretic nature. When the ambient temperature decreases continuously, accumulated ice thickness has a significant positive correlation with accumulated temperature. When it rises, there is a negative correlation.
