摘要：
It is shown that homogeneous plane symmetric string cosmological model for Takabayasi string i.e. rho=(1+omega)lambda does not exist in Barber's second self creation theory. Further it is found that the string cosmological model in this theory exist only when omega=0. Therefore model for rho=lambda (geometric string) is constructed. Some physical and geometrical properties of the model are discussed.
