主　　题：regularity random interactions sd bosons 

摘      要：Atomic nuclei are complex systems with gigantic configuration spaces, therefore truncations of model spaces are indispensable. Due to the short-range nature of the nuclear interactions, one may resort to a truncation by using coherent nucleon-pairs which are conveniently further simplified as bosons, such as sd bosons. The discovery of the spin-zero ground state dominance with random two-body interactions led to a series of studies on regular structure for sd bosons in the presence of random interactions, and this review article summarizes studies along this line in last two decades. We concentrate on various patterns exhibited in sd boson systems, and demonstrate that many random samples which were thought to be noisy exhibit very regular patterns, some of which are interpreted in terms of the V（5）, O（6）, O（6）, SU（3）, and SU（3） dynamical symmetries of the sd interacting boson model.
