Fatigue properties and intrinsic mechanism for the environmental-friendly piezoelectric materials for actuator applications

open access: yes上海师范大学学报. 自然科学版, 2015
We calculate the tensor-to-scalar ratio in a G-inflation in this paper.In our model,we can avoid the behavior that the contribution of higher order is too much to screen the lower order Lagrangian,or vice versa.Every order Lagrangian of Galileons ...
