For the coarsest scale there are fewer local minima and further apart from each other. 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.

大尺度上反问题的目标函数局部极小少而且互相分得很开，因而用常规的反演方法可以较容易地收敛到全局极小的邻域内；将大尺度的解当作次一级尺度反问题的初始模型，再进行反演。

sobel operator is one of common image fringe detection techniques, using image element's left and right, top and bottom neighborhood field's ash degree weighting algorithm, basing on the principle of reaching extremum at the fringe dot, we carry through fringe detection.

And then the designing process and method of the system are expatiated, including the analysis of the system performance, functional module partition, equipment selection and installation, dynamic real-time image acquisition, defect detection arithmetic, and so on. It is worth mentioning that, we have creatively achieve to capture the dynamic images of blood lancets automatically, and we have designed a simple but effective arithmetic for detecting defects according to the image features of blood lancets. Finally, we analyse the experimental results and evaluate the system performent.

本试验运用固定标准地观测的方法测定辽东山区几种主要林分类型的蒸发散量，根据布兰尼—尼里德尔模型推算的后楼水库集水区邻域范围内的年土壤和枯落物水分蒸发量分别为落叶松幼龄林720 mm/a、落叶松中龄林751 mm/a，红松幼龄林762 mm/a、红松中龄林826 mm/a、柞树林677 mm/a、杂木林741 mm/a。

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。

This form of speciation occurs where the speciating populations are contiguous but subject to different environmental e.g.

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.
