The scheme is proved to preserve well the total energy  in  the  discrete  sense,  which  is  consistent  with  the  conservative  property  possessed  by  the  original   problem. Numerical results are reported to show the high accuracy of the numerical methods and confirm the energy conservation.   }, issn = {3080-180X}, doi = {https://doi.org/}, url = {http://global-sci.org/intro/article_detail/jics/22409.html} }
