This essay analyzes the method and procedure of ice-making recorded in Huai Nan Wan Bi Shu, and creatively proposes that the principle of "ice-making in summer" is refrigeration through the quick evaporation of water to absorb heat under low pressure, and that ice is made on the fine silk at the mouth of an urn, but not inside the urn at its bottom as it was conventionally thought. The essay points out three necessary conditions which should be fulfilled in order to realize "making ice in summer": low relative humidity (less than 26%), large volume of the urn (about 100 L) and proper air temperature (about 20℃).

分析《淮南万毕术》所载制冰方法和过程，提出低压下水快速蒸发吸热制冷是"夏造冰"的制冰原理；结冰的部位不是传统观点所认为的瓮底，而是在瓮口的嫌上；指出要实现"夏造冰"，需满足三个条件：相对湿度低（低于26%）、瓮的容积大（100升左右）、空气的温度适当（20℃左右）。

In the past fifty years, ice radar has been widely applied to measure ice sheet thickness, internal structure and subglacial morphology. These parameters are fundamental for the calculation of ice volume and mass balance as well as the reconstruction of past snow accumulation and melting rates, ice dynamics and deposition process.

在过去的50年里，冰雷达被广泛用于测量冰盖厚度、内部构造和冰下地貌，这些参数是计算冰盖体积和物质平衡、重建过去冰雪积累和消融率以及冰盖动力和沉积过程的基础。

As the beginning of this thesis, the important meanings of sea ice to global climate change and ocean engineering in polar and subpolar sea regions are explained firstly. Then, it is pointed out that sea ice numerical modelling, as a powerful tool of sea ice research, is limited by the precision of parameters within models instead of itself so far. It is meaningful to study the important parameters of sea ice dynamics by means of the rapidly developing digital imaging techniques so as to provide better input parameters needed in numerical models.

文中首先阐述了海冰对全球气候变化和极区、亚极区海域海洋工程问题的重要性，并指出作为海冰研究重要手段之一的海冰数值模拟发展到目前，其准确性更加受到海冰参数而非模式本身的限制，因此以目前快速发展的数字图像技术为工具对海冰动力学过程中的重要参数进行研究，以提供数值模式所需要的高精度和准确性的数据，是非常有必要的。

The field geological research indicates that the permafrost type is mainly of much ice- more ice - most ice, and there are ice layers containing soil distributing in the swampland area.

格陵兰冰原将全岛覆盖，仅在狭窄的边缘有少量岩石露出。因为动、植物贫乏，故有人将格陵兰的冰原称为&冷荒漠&。南极洲冰原不但将全陆地覆盖，而且有些地方扩大至海上。冰原的厚度有些地方可达数千米。

Ice/ridge geometric parameters is established, and from computational analysis it is found that the unmonotonous variations of drag coefficient with ice concentration that frequently observed in sea ice field investigation mostly result from the influence of form drag from ice edge.

通过将原型条件下的冰-水总拖曳力考虑成表面摩拖曳力、冰侧形拖曳力和冰脊形拖曳力三部分，建立了冰-水总拖曳系数同海冰和冰脊几何形态参数之间的定量关系，并由计算分析发现现场观测到的拖曳系数随密集度的非单调变化就是冰侧形拖曳力分量作用的重要体现。
