摘要
目的概述空气负离子(NAI)应用研究的新进展,为其广泛应用提供参考。方法对近50年来的研究进行统计分析,并对一些重点应用进行简要概述。结果简要回顾了NAI的历史,根据SCIrus数据库的统计结果,自1960年以来的近50年的文献变化呈现出指数增长态势,同时对其应用从7个方面进行了概述。结论NAI对生物的生长发育具有良好的促进作用,有益于农作物生长和人类健康,但是需要达到一定量的浓度。世界卫生组织对于新鲜空气中的负离子浓度界定为1 000～1 500 ions/cm3。
Aim The new progress in the research and development of negative air ions （NAI） is reviewed to provide a reference for their application. Methods Document rnetrology was used to analyze the papers published since 1960 in SCIrus database and some important applications of NAI will be introduced. Results The history of NAI is looked back, Since 1960 the publications on NAI have been increased in exponential by SCIrus database statistical analysis, and the 7 differential application fields of NAI are summarized. Conclusion NAI has good role for growth and development of biological, such as promoting the growth of crops and are beneficial to health by their inhalation and absorption, but it needs to reach a certain amount of concentration. World Health Organization advises that the concentration of negative ion in fresh air shouldn＇t be below 1 000- 1 500 ions/cm3.
