The behavior of the new model is investigated anaiytically and numerically. The stability, neutrai stability, and instability conditions of the uniform flow are obtained by the use of linear stability theory. The stability of the uniform flow is strengthened effectively by the introduction of the backward-looking effect. The numerical simulations are carried out to verify the validity of the new model. The outcomes of the simulation are corresponding to the linearly analyticai results. The analytical and numerical results show that the performance of the new model is better than that of the previous models.展开更多

Six to One represents the writer's early pastoral ideal with its traditional romantic plot of retiring form city life and living on a reclusive island for a while. In Looking Backward, however, Bellamy embraces machine and technology and even considers industrialism to be the panacea for social reform. In Equality, the sequel to Looking Backward, Bellamy tends to reconcile and balance between industrialism and pastoral ideal with his advocacy of decentralized suburbs rather than centralized metropolis in the prequel.展开更多
