In order to complete the segmentation of the color image,the system is divided into the color quantization phase,color cluster feature phase and the region-growing phase.

本文针对真彩色图像以系统的形式给出了一种彩色图像分割算法，分为颜色量化、颜色聚类、区域生长三个阶段来完成一幅彩色图像完整的分割过程。

There are rich phase structures in QCD at finite temperature and baryon chemical density, for instance, from hadron gas to quark-gluon plasma, chiral symmetry breaking phase and its restoration phase, the color superconductivity at low temperature and baryon chemical density.

在有限温度和重子数密度下，QCD包含了丰富的相结构，从强子气体到夸克-胶子等离子体，从手征对称性的破缺相到恢复相，在低温高重子数密度下的色超导等等。

The fundament of flat terrain phase effect and its removal are stated. The interferogram consists, for each pixel, of the complex conjugate product of two SAS images directly, which cant reflect the actual terrain change. The general phase trend in range can be considered as the phase generated by an ideally flat terrain and is often subtracted from the interferogram before further processing.

论述了水平地形效应产生原理及其消除方法，由于水平地形效应的存在使得两幅SAS复图像直接复共轭相乘得到的相位图不能直观地反映出实际地形的拓扑变化，所以在对干涉相位图进行滤波及相位展开处理前应当消除干涉相位图像的水平地形效应。

Chapter 1 reviews recent investigation in Bose-Einstein condensation, and analyzes critical point and condition of phase transition. Chapter 2 introduces the experiment of Mott insulator and superfluid phase transition in dilute atomic gases, theoretic mode and some studying. In chapter 3, we study the influence of dipole-dipole interaction of two component BEC in optical lattice, by Green function technique and mean-field approach. The results show that long range interaction and dipole-dipole interaction can be strongly influence the phase transition of two component.

本文内容分为四章，第一章对BEC近几年的研究回顾，分析了理想情况下凝聚的临界行为和凝聚条件；第二章我们介绍了光格子中绝缘-超流相变和理论模型及其描述；第三章我们利用格林函数和平均场近似的方法，对偶极-偶极相互作用在光格子中两分量BEC原子的超流-绝缘相变的作用进行了分析，结果表明偶极-偶极相互作用和长程相互作用对绝缘-超流相变有很大的影响。

This contour phase correlation method is superior to the conventional phase correlation in two aspects. Firstly, the contours of images are extracted, and the phase correlation is applied to the contours of images instead of the whole original images, which is more efficient and robust. Secondly, when there are multiple peak values approximate to the maximum peak value in the δ function array, the corresponding translations can be regarded as candidate translations and calculated separately, and the best translation should be determined by the optimization of conformability of two images in the overlapping area.

本轮廓相位相关算法对常规的相位相关算法作了两点改进：(1)提取出图像的轮廓，只对二值化的轮廓图像进行相位相关计算，效率和鲁棒性提高；(2)当相位相关的δ函数阵列中存在多个和最大峰值比较接近的峰值时，将其对应的平移量都作为候选平移量，然后根据重叠区图像的一致性选取其中的最佳值。

从利用图像信息的角度，系统分析了图像特征检测问题的研究文献，将图像特征检测方法分为两大类，即基于梯度信息的方法和基于相位信息的方法。

The phase-shifts caused by reflection and transmission of the beam splitter were investigated by its eigen-martix.The general relationship between these phase-shifts of two splitted beams used for coherent combining was obtained,then the fact that when constructive interference occurs in one side of the beam splitter and the destructive interference has to occur in the other side was explained in the point of phase-shift.

利用分束器的特征矩阵研究了分束时产生的反射与透射相移，得到了两束相干光经过分束器分束后进行相干叠加时相移满足的普适关系，从相移的角度解释了分束器一侧发生相长干涉时另一侧必然发生相消干涉这一现象。

The three-phase AC power phase sequence to identify and phase sequence control in industrial and agricultural production is of great significance.

三相交流电源的相序识别与相序控制在工农业生产中具有重要的意义。

The course of conventionalization is very complex, and between the phase of unset phrases and idioms, there is a mid-phase, that is, the phase of quasi-set phrases.

非固定短语演化为熟语的过程是及其复杂的，并非一步到位，一般来说，中间都要经历一个过渡阶段，即准固定语阶段。

The local ordered CoPt〓 Ll〓 phase with good FCC (111) crystalline orientation, which exists at the interfaces of multilayers and in alloy films, was considered to contribute to the PMA in Co/Pt multilayer and Co-Pt alloy films. But the appearance of large amount of ordered CoPt〓 Ll〓 phase or completely disordered Co-Pt phase will result in the decrease in PMA.

Co/Pt多层膜界面处或Co-Pt合金膜中具有FCC（111）织构特征的局部有序CoPt〓 Ll〓合金相的形成被认为可能会对多层膜和合金膜中的垂直磁各向异性作出贡献，但大量CoPt〓 Ll〓有序相或大量完全无序Co-Pt合金相的生成都会导致垂直各向异性的下降。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
