中文摘要：

利用李群方法,导出了一个非可积（3＋1）维YTSF方程的对称以及该方程的若干对称约化,结合（G′/G）展开法并借助符号计算软件,得到了该方程一些新的精确非行波解.

英文摘要：

By means of Lie group method,the symmetry of a non-integrable（3＋1）-dimensional YTSF equation can be easily derived and some kinds of symmetry reduction are given.Some new explicit non-traveling wave solutions are obtained using the（G′/G）-expansion method with the help of symbol computation software.
