摘　　要：传统的电子鼻实验方法仅凭经验设定操作参数,难以保证实验的可重复性和最大有效性。将实验设计(DOE)方法引入电子鼻的实验研究中,利用中心复合设计快速确定实验点,以模糊修正综合响应最大为目标,对预富集—电子鼻系统的关键参数进行优化。理论分析与实验结果表明:该优化方法有利于电子鼻实验的可重复性开展,并能以最小的实验代价获取最大的实验信息。Operational parameters are decided only by experience in traditional electronic nose experiment methods, which can＇t make sure the experiments＇ repetition and the maximum efficiency. So the design of experiment is introduced to experiment of electronic nose. Central composite design is used to ascertain the experimental point quickly,and for the target of the biggest fuzzy corrected synthetic response, key parameters of preeoncentration-electronic nose system is optimized. Theory analysis and experimental result show that the optimization method conductes to repetitious experiment of electronic nose, and which can obtain the maximum experimental information for the minimal experimental cost.
