The online measurement of Dioxins in the waste incineration is difficult and could only be analyzed with small samples offline. Aimed at the problem, a novel soft sensing methodology with good generalization is studied. Firstly, the small samples are increased with diversity by injecting noise and using the bootstrap resampling approach. Then, the neural network with maximum entropy is presented by introducing information entropy to error rule function for the unknown distributing of original samples. Finally, a soft sensing model of dioxins is built with this entropy neural network. Simulations show that the model has good generalization and precision. The mean and maxim values of relative error between true and prediction of dioxins is 0.167% and 1.21%, respectively. It provides a referenced method for detecting dioxins online in the waste to energy. À¬»ø·ÙÉÕ¹ý³ÌÖеĶþ¶ñÓ¢ÄÑÒÔÔÚÏß²âÁ¿, Ö»ÄÜͨ¹ýÀëÏß·ÖÎö»ñµÃÉÙÁ¿Ñù±¾.
