摘      要：Non-static plane symmetric cosmological solutions are presented in the presence of cosmic strings in the scalar-tensor theory of gravitation formulated by Sen ＆ Dunn. It is shown that string cosmological models representing geometric strings （ρ = λ） and massive strings （ρ ＋λ = 0） do exist in this theory. Further, it is found that the Takabayasi string, i.e. ρ= （1 ＋ζ）λ, does not exist. Some physical and geometrical features of these models are discussed.
