摘要：
The entropy squeezing of a two-level atom in motion interacting with a quantized field is investigated. It is shown that the information entropy squeezing is more precise than the variance squeezing as-a measure of the atomic squeezing and the moving atom may exhibit long time entropy squeezing effect for some choiced system parameters.
