Abstract: In order to investigate the agreement and difference between adjoint and forward calculations with Monte Carlo method， three models have been simulated， and the calculated results are compared and analyzed. First， the comparison shows that the calculated results of the adjoint calculation are basically consistent with those of the forward calculation in modelⅠ. The FOM value of adjoint calculation is about two times of the value of forward calculation. Second， it is investigated with modelⅡ that the applicability of the adjoint calculation for the different materials， and the results show that the difference is about 20% for the case of strong scattering between the adjoint calculation and forward calculation. The FOM value of the forward calculation is larger than that of the adjoint calculation. Finally， the important function is generated by the adjoint calculation in model Ⅲ， and the results are compared with ones of the weight window game. Although their important functions are produced by different mechanisms， the values of functions are in agreement with each other， and the FOM value of ajoint calculation is about 1.5 times of the value from the weight windows.
