As a result of BB's (Beckleman Beam) system deficiency, the data collected from BB are always very different from the actual ones, which can even affect the Normal Distribution sometimes.In this article a new method-wavelet transfonn is introduced to de-noise the data with errors and try to solve the problems mentioned above. After compared with the original data, the denoised data shows good consistency with the original ones in statistics, it can correct the distribution form of the data which has departed from the Normal Distribution It is proved that the wavelet transfonn is suitable for denoising the data with errors and disturbance.
