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。

Flooding,as a kind of disturbance events,occurred with higher and higherfrequency over the world.To investigate the effects of flooding disturbance ongrassland vegetation and the soil,a comparatively thorough study was conducted onAneurolepidium chinense grassland in Songnen plain,Northeast China.The studysite was located in Sanjiadian National Rangeland in the territory of Da'an city,Jilirprovince,which was partly flooded in 1998.On the study site,Several transectssubjected to different flooding durations and intensities were designed for thecomparative study among them on such aspects as vegetation characteristics,seedbanks,vegetative propagation of rhizomatous plants,distribution patterns ofpopulations,interspecific relations,and physio-chemical properties of soil.Theresults were as follows:(1)Of the functional group composition of the vegetation,with the elongation of the flooding duration or the increase of flooding severity,theratio of hygric and hygro-mesic plants increase,while that of mesic and mesoxericplants decrease,of Therophytes changed unimodally,of Geophytes increased,whileof Hemicryptophytes decreased.
为弄清草地植被及其土壤环境对水淹干扰的响应,在松嫩平原羊草草地1998年部分遭受水淹的吉林省大安市三家甸子草场内设置了经历不同水淹干扰持续时间和不同水淹强度的样带,并在这些样带之间从植被特征、种子库特征、根茎植物的营养繁殖性能、种群分布格局、种间关系及土壤的理化性质等多个方面展开对比研究,主要结果如下:(1)在植被的功能群组成中,随干扰强度的增加和水淹干扰持续时间的延长,湿生、湿中生类植物功能群的优势度比例基本上是逐渐增加的,中生、中旱生类植物功能群的优势度比例则逐渐减小,而一年生植物的优势度比例呈单峰型变化,地下芽植物比例增加,地面芽植物比例减小。
