For ammunition film drying stove temperature control is not ideal actual situation, in order to further improve the precision of temperature control, we according to the artificial intelligent adjusting instruments the characteristics of system improvement, from the structure, algorithm, parameter setting and actual inspection, etc are discussed in detail. The results show that the fuzzy PID with artificial intelligence technology of ammunition film drying stove temperature in the improvement of the system is feasible.

Abstract. In the paper based on diffusion theory the acid rain erosion-carbonization model was established. The model parameters were analyzed and the model was solved by MATLAB software. At same time the failure criteria of existing concrete structure in acid rain area was developed and the life prediction method was proposed. Finally, combined with the acid rain feature in Nanchang the multi-storey teaching building life was predicted to prove the validity of the model. The calculation showed the acid rain damage to the building in Nanchang is more serious. It should be taken seriously enough.
