英文摘要：

Dynamic Bayesian error function of temperature field is founded on the first time in this paper. Dynamic Bayesian estimation theory is applied for the stochastic estimation problem of concrete temperature field parameters. The corresponding formulas of dynamic Bayesian expectation and variance are deduced. The optimization estimation computing formulas are also deduced by adapting gradient method and the computing steps of dynamic Bayesian estimation are given in detail. Though a practical example, some important conclusions about dynamic Bayesian estimation of temperature field parameters are drawn.
