The influences of decay coefficient of the cavity and the intensity of the field on the phase distribution as well as its fluctuation are discussed.The results show:if there is absence of the phase damping,the phase distribution oscillates with the period π/λ.It presents single leaf at t=nπ/λ,but it splits into multi-leaf construction during the evolution period due to the interaction between the field and the atoms.

Both of the ESD were proportional to kVp 2.2 to kVp 2.5 and were linear proportion to mAs. Inverse square law exists in the relationship of focus-film distance, FFD, and ESD. The impacts of field size and patient thickness to ESD are negligible. Optimized operating condition is chosen to improve the diagnosis rate and to reduce the patient dose. The ESD, 0.12±0.06 mGy, performing the optimized operating condition of chest x-ray examinations, is less than both values of reference doses recommended by NRPB and IAEA.
