英文摘要：
In order to improve effectively temperature compensation characteristic of sensor, the model fitting the temperature characteristic curve based on the neural network algorithm with Fourier basis functions was presented. The convergence performance of the algorithm was proposed. The theory gist to select learning rate is provided by the convergence theorem. The simulating example of the sensitivity-temperature characteristic curve of the SnO2 nanosensor mixed with benzene was given. The result shows that the temperature characteristic curve fitting of sensor using the neural network algorithm with Fourier basis function is both smooth and accurate. The fitting precision is up to 10.6. Therefore, the method of curve fitting based on the neural network algorithm is effective.
