摘要：
The second-,fourth-and sixth-order fluctuations have been discussed by making use of SU(2)Lie algebra. On the basis of higher-order uncertainty relation,the definition of higher-order squeezing for the fluctuations of angular momentum has been put forward. In particular,the second-,fourth-and sixth-order squeezing in atomic coherent states are investigated. These methods and definition can be used for studying much higher-order squeezing. The higher-order squeezing can be generalized to the fluctuations of atomic variances thereby.
