摘要：
Superfluidity of q-deformed bosons with weak interaction is studied. Bogoliubov's method of approximate second quantization is applied to this case. Under the condition p(2)/m much greater than ([N]/V)U-0, the spectrum of elementary excitations is found to be of the roton-type, and hence superfluidity is predicted.
