缓释技术的研究现状与展望

摘要

Slow release technology was that in a particular system took certain measures to slow the release rate of a particular substance.Thus, in a certain period, the concentration of the substance can maintain to improve the utilization efficiency.The mechanism of low-release and evaluation methods was summarized , and the widely applications of slow -release technology in many aspects were described , such as pharmay , agriculture , chemical industry and other areas.According to the analysis , the future development trend was prospected.%缓释技术是指在特定的体系内，采取某些措施来减缓某种特定物质的释放速度，因而可以在一段时间内使该物质保持一定的浓度，提高利用率。本文介绍了缓释技术的机理和性能的评价方法，综述了缓释技术在医药、农业、化工等领域的广泛应用，并对缓释技术进行了展望。
