小金字塔

哈夫拉金字塔（图1d）比基奥普斯金字塔小不了多少，它现在的高度大约是450英尺，而排第三的门卡乌拉金字塔只有大概210英尺高。

There are several groups of pyramids, large and small at Gizeh and elsewhere, almost all of which belong to the Old Empire. The three great pyramids of Gizeh are among the earliest. They were built by three kings of the Fourth Dynasty, Cheops, Chephren, and Mycerinus They are gigantic sepulchral monuments in which the mummies of the kings who built them were deposited. The pyramid of Cheops Fig.

在吉萨和其他地方，有几组金字塔，或大或小，几乎所有金字塔都是旧王朝时期的遗物，吉萨的三座都属于最早的一批，它们由第四王朝的三个国王，基奥普斯、哈夫拉和门卡乌拉修建，是巨大的陵墓纪念物，修建金字塔的国王的尸体木乃伊被保存在其中。

Every Friday five crates of oranges and lemons arrived from a fruiterer in New York—every Monday these same oranges and lemons left his back door in a pyramid of pulpless halves.

The carved gable, the pointed roof, the turrets suspended at the angles of the walls;the stone pyramids of the eleventh century, the slate obelisks of the fifteenth; the round, bare tower of the ''.

石砌的山墙、尖角的屋顶、墙拐角悬空的小塔、石垒的金字塔、十五世纪石板方碑、城堡光秃秃的圆形主塔、教堂精细装饰的方形塔，大的，小的，粗大厚重的，小巧玲珑的，纷至沓来，叫人目不暇接。

Based on the traits of dyadic wavelet decomposition of signal and that of the distribution of wavelet image coefficients, PLVQ and ZR are conjoined by making use of D\-4 lattice. Firstly, Pyramidal lattice vector quantization is adopted to quantize wavelet image coefficients. Nonzero lattice vectors and zero lattice vectors are formed. Secondly, nonzero lattice vectors are dealt with by adopting complex entropy coding. Finally, in order to fix on the position of nonzero lattice vector effectively, that is, to deal with zero lattice vectors effectively, the concept of significant map is introduced into. The significant map is scanned two times from down to up and from up to down.

根据信号的二进小波分解特点和小波图象系数的分布特点，利用D\-4格将PLVQ和零树结合起来，提出了一种基于零树和金字塔格型矢量量化的小波图象编码方法，该方法首先采用金字塔格型矢量方法来量化小波图象系数，以得到非零格点和零格点；然后采用复合熵编码来处理非零格点；最后为了有效确定非零格点的位置，也就是为了有效地处理零格点，又引进了重要图的概念。

Based on analyzing wavelet analysis and digital elevation model, the paper presents the truth that multi-resolution wavelet can be used to simplify DEM data and to create the pyramidical image model.

首先分析了小波分析的特点和数字高程模型的特性，说明多进制率小波变换可以在DEM数据简化和影像金字塔模型构建中发挥重要作用。

The image pyramid is obtained by using the wavelet transform, and then we do the registering work at each level of the image pyramid. And the image grade method is applied at the coarsest level of the image pyramid, while Mutual information registration method can be performed at the rest of levels with the result at the pervious level serving as the initial condition.

通过小波变换构造图像金字塔，在每一层的平滑逼近分量上进行图像配准，并在金字塔最高层的近似图像上使用了梯度法进行图像配准，而在其余层上继续使用基于互信息的配准方法。

Source images with wavelet are decomposed, and corner information can be detected in the two approximate sub-images on the wavelet coarsest level. The initial registration parameters are achieved through affine transform model. The optical flow is iteratively refined to get the coarse registration parameters. The process will continue until the final and accurate matching parameters are obtained.

首先对源图像进行小波分解，在小波金字塔最顶层的低频近似子图像上进行角点检测，通过仿射变换模型得到初始配准参数；然后将这一参数逐层进行迭代精炼，直至达到金宇塔最底层，得到最终精确的配准参数。

This type of aromatherapy oil warmers is generally small and often they are shaped like pyramids.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
