摘要：
The gravitational field of a superconducting cosmic string in the context of Lyra geometry is investigated. It has been shown that such a string has only a repulsive gravitational effects on a free moving particle. It is dissimilar to the case of a superconducting cosmic string in general relativity and Brans-Dicke theory, which gives rise to an attractive effect.
