摘      要：A simpler and improved utility approximate point scattered function for thin-film converters currently used in neutron photographic devices is proposed as a correction method to produce clearer,more realistic *** validity of the model was demonstrated through a simulation *** on the results,an error analysis was carried out,certain corrections were made to the original model,and the final model achieved a very low relative error in the simulation *** model can also be optimized for quantitative neutron photographic analysis using iterative algorithms to obtain realistic neutron photographic images more *** the end of the article,the model is extended to consider the case of energy spectrum hardening by introducing a temperature correction parameter.
