Based on numerical simulation flow after treatment methods and implementation. This paper drawing river ice jam thickness contour map, vertical water flow under the ice jam contour map as an example, the use of Surfer software described in detail various graphics rendering; Focused on the Surfer with VB programming software secondary development to achieve flow numerical simulation after treatment, showed that automatic change the data files to the Surfers;Introduced Active automation technology and Visual Basic Application Program Interface, and the interface technology will combinate VB powerful software development capabilities and Surfer software powerful mapping functions , achieve the key code and the mapping results map examples: under the ice sheet flow velocity field vertical contour map, three-dimensional wire-frame plans, such as flow field vector graphics, and dynamic display and output the graphics.

基于水流数值模拟后处理的方法与实现，本文以绘制河流冰塞厚度等值线图、冰塞下水流纵向流速等值线图为例，详细介绍了运用Surfer软件绘制各种图形的方法；重点阐述了用VB编程对Surfer软件进行二次开发实现水流数值模拟后处理，显示向Surfer数据文件自动转换的过程；介绍了Active自动化技术及其与VB应用程序的接口技术，并利用该接口技术将VB的强大软件开发能力和Surfer软件强大的绘图功能相结合，给出了实现该接口技术的关键代码以及绘制成果图件的实例：冰盖下流速场纵向流速等值线图、三维线框图、流场矢量图等图形，并输出图形与动态显示。

So they watch for bulletins from the International Ice Patrol, which has been monitoring ice movement in the area since 1914 (it was founded in response to the Titanic's sinking two years earlier), and send out the ice wranglers, who use ropes and high-powered boats, to steer them away.

所以他们密切关注国际冰巡逻队发布的公报，该组织自1914年就一直在监测本地区冰块的移动（该组织的成立就是为了对两年前发生的泰坦尼克号沉没事件做出反应），并派出冰川牧人，使用绳索和大马力船只，将冰山拖离平台。

The present ice ages are the most studied and best understood, particularly the last 400,000 years, since this is the period covered by ice cores that record atmospheric composition and proxies for temperature and ice volume.

目前的冰河是最了解的最佳研究，特别是近40年来，由於这是所述冰芯记录的大气成分和温度，雪量为代理人。
