数字数据

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。

This number is a little deceptive because only 480 to 486 of these lines contain video information; the remaining 39to 45 lines are reserved for sync pulses to keep the television's circuits synchronized with the video signal.

因为在这些线中的只有80到486条包含了电视信号的数据；剩余39到45条行被同步脉冲保留用以维持电视能与信号一起同时被使用，所以这一个数字稍微具有一定的迷惑性。
