Abstract：The investigation into wave‐particle duality of the photons is still an important and at‐tracting subject in physics .By using the theory of probability and the statistical interpretation of the wave function ,a delayed‐choice experiment is analyzed here .The results show that the probability of the test photon being either horizontally or vertically polarized is 1/2 ,w hich is independent of the cor‐roborative photon measurement apparatus ;the behavior of the test photon is completely determined by its polarization state and is independent of the detection of the corroborative photon ;the coincidence de‐tection probability between the test photon and the corroborative photon varies with the state of the cor‐roborative photon measurement apparatus ,which means that the test photon’s wave behavior cannot be changed into particle behavior by morphing the state of the corroborative photon measurement apparatus .
