The electronic nose for gas quantitative analysis is designed through combining gas sensor array with gray system theory. The gray prediction model GM(1, N)is set up according to experimental findings got from sensor array. The model is used to analyze the gas volume fraction. The experiment shows that the quantitative gas analysis based on gray system theory is feasible.%将气体传感器阵列与灰色系统理论相结合,设计出用于气体定量分析的电子鼻.根据传感器数列得到的实验数据为基础数据建立了气体定量分析的灰色预测模型GM(1,N),并通过该模型对气体的体积分数进行了分析.实验证明:灰色系统理论用于气体的定量分析是可行的.
