复数,实数及实对称数据下Bruun FFT算法的实现

本文在复数、实数以及实对称数据下研究和实现了Ｂｒｕｕｎ ＦＦＴ算法。文章分析和评价了各种数据下ＢｒｕｕｎＦＦＴ的运算量和特点，提出了算法的实现结构和方法。最后给了ＴＭＳ３２０Ｃ３０上的运算时间，我们实现的算法比基２ＦＦＴ速度提高３５％。     

西部农业信息化建设问题的探讨

西部农业信息化水平低下制约着西部农业的发展。物质基础薄弱、信息意识淡薄、信息人才及资金短缺是造成西部农业信息化水平低下的原因。为加快西部信息化农业建设，应该从更新观念、加大政府支持力度、利用有限资源进行信息化基础建设、重视人才资源的开发、培育信息产品市场、加强农业应用系统和信息化农业技术的研究、加强示范应用体系等方面入手。     

Plasma prostaglandin levels in fed and starved lean, normal and obese women.

The plasma obtained from fed and starved lean, normal and obese women was estimated, by a radio-immunoassay method, for prostaglandins, owing to their implication in the regulation of adipose tissue lipolysis and the development of obesity. No significant differences were found due to nutritional status or body-build. However, a significantly higher plasma concentration of prostaglandins of the E-type than of the F-type, was found consistently. The very low levels of prostaglandins observed (a range of 0.10--0.15 ng ml-1 for E-type and a range of 0.05--0.07 ng ml-1 for the F-type) may be due, in part, to the activity of a plasmatic prostaglandin metabolizing system.     

研究型大学图书馆的人力资源管理

引入研究型大学及其图书馆的定义，阐述了研究型大学图书馆进行人力资源管理的重要意义。进而提出了研究型大学图书馆人力资源管理的策略，包括改变人力资源管理理念，建立以人为本的人才管理机制，注重人才的使用和培养，充分调动馆员的积极性等。     

浅谈用人之道

人才是提高综合国力的关键要素。为用好人才，一是要辨证地把握好识别人才、起用人才的标准，既要选拔出德才兼备的人才，又不可求全责备；二是用人要讲究方法。做到公平竞争、择优录用、知人善用，同时鼓励人才合理流动；三是用人要遵循讲正气、讲民主、讲大度的原则，大胆使用人才。     

Plasma prostaglandin levels in fed and starved lean,normal and obese women

Summary The plasma obtained from fed and starved lean, normal and obese women was estimated, by a radio-immunoassay method, for prostaglandins, owing to their implication in the regulation of adipose tissue lipolysis and the development of obesity. No significant differences were found due to nutritional status or body-build. However, a significantly higher plasma concentration of prostaglandins of the E-type than of the F-type, was found consistently. The very low levels of prostaglandins observed (a range of 0.10–0.15 ng ml^–1 for E-type and a range of 0.05–0.07 ng ml^–1 for the F-type) may be due, in part, to the activity of a plasmatic prostaglandin metabolizing system.Acknowledgments.
