According to three matching words, the forgetting mainly occurs in the first 30minutes, and after that, it turns even. After two retrieval processes dissociate, the contribution of automatic is much more than that of consciousness for all the subjects. In the retrieval of positive words, the automatic retrieval of Ss and Ns has great individual difference. The Is and Es towards extroversive words have great individual difference too.

Contrast to the image retrieval ,the research in the audio field lagged.This paper summaries the situation of audio retrieval ,combining with material of the MPEG standard and content based retrieval .And propose the protype of a Query by humming sytem based on the ICA,which can solve the cocktail problem very good.

The main results in this paper as follows: First, a prototype of a shape-based image database retrieval system is completed, it can receive the query mode both by giving an example image and by sketching the desired object on the screen, Second, five shape-based image retrieval methods are realized; Third, an algorithm based on triangulation for shape-based image retrieval is brought forward. In this algorithm, firstly, the edge of the original image is followed and the candidate corners in the original image are detected. Then the counterpoints of the candidate corners in the result of edge follow are found, and the boundary corners whose counterpoints have been found are queued in the order of their counterpoints in edge follow. After these steps, the boundary corners are triangulated and triangles are obtained which can show the true shape of the original image. Finally, shape feature is obtained by calculating the angle histogram of the triangles.

同时本文中主要完成了以下三方面的工作：完成了一个基于形状特征的图象检索的原型系统，可实现例子图象或徒手绘草图两种查询方式；实现了五种利用形状特征进行图象检索的具体方法，并对其进行了分析比较；并且在继承将三角剖分引入形状检索的思想基础上提出了利用三角剖分进行形状检索的一种新算法：先对原图象进行边界跟踪和角点检测；然后寻找初始角点在边界跟踪中的对应点，并对找到对应点的角点按其对应点在边界跟踪中的顺序进行排序；再对排序后的角点进行德洛内三角剖分，得到能表示目标真实形状的三角形序列；最后计算三角形序列的角度直方图作为形状特征，并进行相似性匹配。

In this paper,the storage forms of sound and image information are first discussed.Then,the authors study and analyse methods and technology that can be used in sound and image retrieval,and give classified expositions.Meanwhile,this paper makes comparative research on data models of the multimedia information retrieval system,proposes that the design of MIRS may base on a RDB system,and it can support storage and retrieval of sound and image information by expanding its ability of managing complex objects and multimedia data.

Transmissions at 0.75 and 1.65 μm can also be used to retrieve τ and re. 2. Study the impact of cloud inhomogeneity on the satellite retrieval simultaneously. Two 3D cloud fields, cumulus and stratocumulus fields are used in our study. The two cloud fields are generated with LES model and are adopted by the I3RC phase II. The BRDF at the wavelengths of 0.65 and 2.13 μm are calculated with SHDOM, and then the cloud optical thickness and effective particle radius are simultaneously retrieved using the MODIS algorithm. We studied the impact of cloud inhomogeneity on the satellite retrieval at high and medium resolutions. Some conclusions have been made, such as the BRDF abnormal phenomenon, the reverse relationship between τ and re, the clustering effect of over and under estimation in the retrieval of τ and re .
