Cosmological constraints on the background dynamics of a two-field nonsingular bounce model
《Chinese Physics C》2024年第11期149-155,共7页Kang Song Ri Sin Chol Hwang Hyon Chol Ri 
In this study,we consider a nonsingular two-field bounce scenario with non-minimal kinetic coupling between two scalar fields.We derive constraints on the model parameters from the finiteness of the physical quantitie...

A range and depth estimation method using the time delay structure of bottom reflection in deep sea bottom bounce area
《Chinese Journal of Acoustics》2024年第3期275-289,共15页XIE Qichen CHI Cheng ZHANG Bo HUANG Haining 
supported by the National Natural Science Foundation of China(62001469).
When the source-receiver depth relationship is unknown,using the time delay differences for distance and depth estimation may result in a pseudo source.To address the issue,a method for directly estimating distance an...
