We introduced the existing domestic and foreign pictures retrieval system and compared with the merit, the system structure and the general processing method which had based on the content picture retrieval system.

本文介绍了现有的国内外图像检索系统，比较了基于内容的图像检索系统所具有的优点、系统结构及一般的处理方法。

The Search engine is not perfect because of the low retrieval efficiency, the high rate of mistakable or missing outcome, the large amount of returned information and the unsolved non-text document retrieval. The mode of "one search for all user", can't meet the user's individualized message requirements.

搜索引擎检索效率不甚理想，漏检误检率较高；返回信息量太大，非文本文件检索困难；"一个搜索适用所有用户"的模式，不能满足用户个性化信息需求。

Its directed graph structure and mixed contents consist of correct candidates and wrong candidates, not only result in very low retrieval accuary for traditional retrieval methods, but also need much more index space and searching time.

其中的一个核心问题就在于，Lattice并不是一个易于索引的数据形式，它的有向图结构，以及正确信息与错误信息相混杂的特点，不但直接导致了传统的检索方法性能不佳，而且也需要较大的存储开销和搜索时间。

The core features of this search engine can make it true for a company to finish a fulltext retrieval from different monogenesis or format datas, which enables the company to get an efficient, correct and safe solution during a data retrieval.

本搜索引擎的核心功能是实现对企业不同源、不同格式数据的全文检索，为企业数据的检索提供高效、准确和安全的解决方案。

Thirdly, phase retrieval by use of Gerchberg-Saxton algorithm based algorithm and phase retrieval by use of a Green's function under Neumann boundary conditions is applied to DGWFS.

第三章分别对基于Gesrchberg-Saxton法的迭代法和Neumann边界条件的Green函数法的波前恢复进行了计算机模拟，并给出了具体程序框图。

However, the state-of-the-art performance of web image retrieval is still far from satisfaction. The main difficulty resides in the fact that the Web is a huge distributed database and on-line users would not like to wait overlong for results of retrieval.

但同时它又是一个极为困难的问题，困难主要来源于Web图像检索环境是一个规模惊人的分布式图像数据库，而且互联网用户一般不愿意花过长的时间等待检索结果。

At the same time, the retrieval method of sun photometer data, including the calibration and retrieval of aerosol optical depth and the quality control of data, is introduced.

同时，针对光度计原始观测资料直接应用的瓶颈问题--资料解读方案进行了讨论，包括定标、气溶胶光学厚度的计算、光度计数据质量控制方法等。

Since the traditional retrieval performance measures, such as precision and recall, are not appropriate for retrieval with multilevel relevance measurement, a new performance measure is introduced, which is based on the preference relation between images.

由于传统的检索性能度量不适合多级相关度量的情况，采用了一种建立在图像间偏好关系上的检索性能度量。

First, in order to verify the correct of this retrieval month, by using the data of three-dimensional wind field, raininess field and temperature field that are output by MM5 numerical simulation, we climate the radial velocity field and echo intention field in the in-phase observation area of Dual-Doppler radar, then, on the base of the upwards retrieval theory and using the radial velocity field and echo intention field in the in-phase observation area of Dual-Doppler radar, we retrieve the atmospheric three-dimensional wind field.

首先，为检验此种反演方法的可靠性，我们使用MM5数值模式输出的三维风场、雨强场、温度场等数据，分别模拟生成两部雷达同步观测区的径向速度场和回波强度场，然后根据以上的反演理论利用模拟的双多普勒天气雷达观测到的径向速度场和回波强度场反演出大气三维风场。

We experimentally evaluate the effect of the proposed method using our emotion retrieval algorithm and random algorithm. Four kinds of emotion images, thick fashion images, succinct fashion images, passional scenery images and wide view scenery images are retrieved and compared. The experimental results show that our retrieval algorithm is better than random algorithm.

文中将本实验室实现的情感检索算法检索出的"厚重的"、"简洁的"服装图像以及"热情的"、"视野宽广的"风景图像与随机检索出的图像进行了比较，验证了基于心理量表的情感图像检索性能评价方法的有效性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
