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。

In the Sixth Chapter, the Wavelet analysis method is introduced in discussing some acoustic imaging problems related to the physical background of the ultrasonic detection. In the light of the solution of some theoretical problem in the 2D Wavelet transmission of two components form, the enhancement and identification of the spotty and fibriform faults of the acoutic image, along with two acoustic image deblurring methods based respectively on the acoustic physical feature analysis and the acoustic image's spatial feature analysis of the object, are realized. Therefore the image degeneration problem resulting from the acoustic beam diffusion or the acoustic focus diffusion in the ultrasonic detection are effectively improved. The software for this purpose has also been developed.

第六章首次应用小波分析的方法，研究了与超声检测的物理背景有关的一些声象处理问题，在解决了二分量形式的二维小波变换中的一些理论问题的基础上，建立起了对声象中点状和线状缺陷目标的增强与分离方法，以及分别基于目标的声学物理特征分析和基于目标声象空间特征分析的二种声象弥散消除方法，实验分析结果表明，这种方法较好地解决了超声检测中由于声束截面或声焦点扩散所造成的成象退化问题。

Fifthly, the conception and the method of image compress is dissertated, also discusses the conception of wavelet transformation、continuous wavelet、discrete wavelet and multi-resolution analyses、Mallat algorithm, and do further research on the characteristic of wavelet images、the choice of wavelet bases and the continuation of image border, and based on this work, the way of freight train images compression combined with the wavelet and JPEG is put forward.

第五，论述了图象压缩的概念、方法，对小波变换的概念、连续小波、离散小波以及多分辨率分析、Mallat算法进行了讨论，并对小波图象的特点、小波基的选择以及图象边界的拓延进行了深入研究，在此基础上提出了小波和JPEG相结合的货车图象压缩方案。

The baby elephant behind her held up his head, waving his trunk to sample the suspicious smell in the wind. suspicious s?

s 可疑的，怀疑的译文：身后的小象仰起头，摇晃着鼻子嗅着风里飘来的可疑的气味。

It's killing Asian elephant adults, and it's a leading cause of the species' infant mortality.

Mason说，它是导致这一种类小象死亡的原因。

The rare species of Asian elephant has only an estimated 34,000 animals left.

澳洲雪梨的一间动物园，周六诞生了一只120公斤重的小象，濒临绝种的亚洲象宝宝，目前全球只有三万四千只，还有另外两只亚洲象也怀孕了，一起去看可爱的亚洲象宝宝，感恩收看，再会。

The little white rat saw that,he said:Give the handkerchief to me!

小象捡起了手帕，不知该往哪儿扔了…。

Tall and short,the two brothers always dressed in clothes of similar colors and styles;hand in hand, the two of them walked through parks and fields, a small elephant, a flying bird, a 'music' mushroom, a guard standing booth, a shell picked up after the tides all became the great surprises and amusements of the day.

一高一矮兄弟两，经常穿着同色系的衣服，手牵手走过森林，踏过田野，一头小象、一只飞鸟、一朵音乐蘑菇、一个卫兵站岗的门厅、一只退潮后捡到的贝壳都是生活中极大的惊喜和收获。。。
