Thus, at the coarsest scale linearized methods can get closer to the neighborhood of the global minimum, and its final result is implemented as an initial model of the inverse problem of the second coarsest scale.

In addition, because motion vectors must be estimated in the process of region's motion parameters estimation, this paper discussed the theory and general methods of two-dimensional motion estimation and proposes a fast motion estimation algorithm based on the prediction of neighbour block's motion vector.

此外，由于在区域的运动参数估计过程中涉及到对运动矢量的估计，因此本文还讨论了二维运动矢量估计的原理和一般方法，并提出了一种基于邻域子块的运动矢量预测的快速运动估计算法。

The above problems are studied in this thesis. First, the implicit NND scheme with mix flux splitting method proposed by Zhang Hanxin that is first order accurate in time and second order in space is modified. The modified scheme keeps the characteristics of fast convergence and is second order accurate both in time and space. It can be capable of simulating the unsteacly flow. Second, the topological method founded by Zhang Hanxin is improved to study the characteristics of vortex near the singular point on its axis and the cross streamlines on the longitudinal section passing the vortex axis. On the basis of topological results, a program which visualises numerical results is made out. It can help us analyse the characteristics of vortex motion.

本文对上述问题做了研究：第一，在数值模拟方面，借助于张涵信提出的NND算法和混合通量法，我们将他建立的时间为一阶、空间为二阶精度的快速隐式算法推广为时间和空间均为二阶精度的算法，这样做保留了原格式收敛快的特点，而且能适用于真实的非定常流态的计算；第二，将张涵信的拓扑分析方法加以推广，研究了涡轴附近及破裂点邻域内流场的空间特征，并以这些拓扑分析结果为指导，研制了一套显示计算结果的软件，这一软件能很好地帮助我们分析流场的计算结果和旋涡演变的特征。
