Retrieval methods of using empirical orthogonal functon, optimal statistics, nonlinear iteration and Chahine iteration for solving the temperature remote sounding equation are discribed in this paper. The comparison between retrived temperature profiles from different methods and radiosonde shows: (1) The nonlinear iterative methods gives higher accuracy of retrived temperature and faster convergence. (2) While the error is larger in the lower atmosphere by the use of empirical orthogonal function method...

Retrieval methods of using empirical orthogonal functon, optimal statistics, nonlinear iteration and Chahine iteration for solving the temperature remote sounding equation are discribed in this paper. The comparison between retrived temperature profiles from different methods and radiosonde shows: (1) The nonlinear iterative methods gives higher accuracy of retrived temperature and faster convergence. (2) While the error is larger in the lower atmosphere by the use of empirical orthogonal function method and optimal statistics method, the error is larger in the upper atmosphere by use of iterative methods. (3) By matching the error distribution at 500 mb level with the radiosonde temperature field it shows that retrival error is larger in trough region, smaller in ridge region.

本文利用经验正交展开,最优统计,非线性迭代,Chahine迭代来求解气温遥测方程。通过对不同天气形势下进行反演计算并与实况相对比,结果表明:(1)利用非线性迭代方法来反演气温垂直分布其精度较高,收敛速度快。(2)利用经验正交展开法与最优统计法其反演误差在大气低层大,反之迭代反演法在高层误差大。(3)从500毫巴等压面反演误差的分布与常规观测所得到的温度场配置来看,往往在槽区反演误差较大,而脊区反演误差较小。

The SKGY is implemented by interpreter using system assemble language XHY, which is machine-independent. The primitive system is implemented on DJS-21 computer. As XHY is...

This paper describes the implementation algorithms of database management language SKGY, with special emphasis on the loading and retrieving of the structures for SKGY.SKGY is a self-contained language designed for minicomputers, its retrieval function is designed by query language, and its data structure is a hierarchical structure. The SKGY is implemented by interpreter using system assemble language XHY, which is machine-independent. The primitive system is implemented on DJS-21 computer. As XHY is transported to other computers, and so is this system.

本文描述数据库管理语言SKGY的实现算法,详细给出了构件的装配与检索的实现过程。SKGY是为小型计算机设计的一种自封语言系统,它的检索功能设计为询问式语言,数据结构是层阶式树型结构。本语言的实现采用解释系统,解释系统用独立于机器的系统汇编语言XHY来写,初始系统是在DJS-21机上实现的,随着XHY移植到其它计算机,本系统也将移植到其它计算机上去。

The present study outlines the general principles, basic features and relavent mathematical models of the information storage and retrieval system QJ-111. The system can he used to retrieve information from bibliographic and some other date bases. With some expansions, the system will become a simplified hierarchical data base management system. The co-operation of QJ-111 information retrieval system with JF-111 machine translation system will result in an operation of retrieving synchronous with translation so that a new perspective is seen in the field of machine translation. Information in Chinese is input in the form of Chinese phonetic alphabet and handled by a Chinese-character translation system. The results are output in the form of Chinese characters. In case Chinese character printer is not available, output will be given in Chinese phonetic alphabet thus achieving certain readability.

本文描述了情报检索QJ-111系统的基本原理、特点和它所依据的数学模型,讨论了各种可能的数据结构和实现方法。QJ-111系统可用来检索科技文献资料,也可用来作某些广义检索;经过改进后,可发展为一个层次结构型的简易数据库管理系统;对中文信息,采用汉语拼音输入,经过汉字翻译系统而以汉字形式输出检索结果。如果不具备汉字打印机,仍可以汉语拼音形式输出,从而具有一定的可读性。
