Abstract：
The contraction of an isolated gas group in the expanding universe has been discussed.It is found that in addition to the contracted conditions of the statical isolated gas group,the initial gas group is straticulate statistical uniform and the initial radius is larger than a critical value D^－1_r,the contracted conditions of expanding case also include that the Hubble constant H is smaller than a constant D_t.
