Soft measurement is a new technology which is come up in fields of detection and process control at recent years.Its basic principle is to use variable that is easy to measure to establish the model to deduce the measured one.The difficult problem that is temperature measurement of microwave sintering materials is discussed.Based on the research of microwave sintering field experiment

the theoretical method of simulation soft measurement is suggested.Through measuring the temperature of non-hot area

the practical temperature of sintering material can be deduced according to theories of heat conductivity and interface thermal resistance.In experiment

microwave oven is used to simulate microwave sintering cavity

then temperature data are gained and model is established.Result shows that the model established agrees with the assumptive exponential model based on the nerve network theory and the feasibility of the method is prove.
