	近海环境中抗生素分析样品前处理技术的研究进展期刊论文 OAI收割色谱, 2020, 卷号: 38, 期号: 1, 页码: 95-103 作者: 吕敏; 陈令新 \| 收藏 \| 浏览/下载：117/0 \| 提交时间：2020/07/08 抗生素近海前处理技术综述 antibiotics coastal pretreatment techniques review The widespread and massive usage of antibiotics for the prevention and treatment of diseases in human and animals have resulted in their continuous discharge into the environment, and finally, into the coastal environment through various pathways. Accumulation of antibiotics in aquatic organisms poses a great threat to ecological and human health, especially because it facilitates the generation and spread of bacterial resistance. Given the diverse range of antibiotics with various features, as well as their presence at low concentrations in the environment, it is imperative to develop pretreatment techniques for antibiotics in various matrices. In this paper, the pretreatment methods proposed in recent decades for antibiotics in coastal water, sediment, and biota are summarized, with emphasis on commonly used methods such as solid-phase extraction, solid-liquid extraction, matrix solid-phase dispersion, and QuEChERS. Additionally, the potential factors influencing the extraction performance and clean-up efficiency are analyzed. The advantages and disadvantages of the methods and their development are finally discussed.
	Research on software defect prediction based on data mining (EI CONFERENCE) 会议论文 OAI收割 2nd International Conference on Computer and Automation Engineering, ICCAE 2010, February 26, 2010 - February 28, 2010, Singapore, Singapore 作者: Chen Y. 收藏 \| 浏览/下载：42/0 \| 提交时间：2013/03/25 As the development of computer technology software system becomes more and more complicated. Because of human's ability limit there must be a lot of defects generated in the software development life cycle. This paper reviewed the state of art in the field of software defect management and prediction and presented data mining technology briefly. Finally proposed an ideal software defect management and prediction system researched and analyzed several software defect prediction methods based on data mining techniques and specific models (Bayesian Network and PRM). With this system we can efficiently draw up some prevention and solution scheme to guide the development of new software. 2010 IEEE.
