In this work, starting from a Painlev?-B?cklund transformation and a multilinear variable separation approach, a general variable separation excitation of the three-dimensional Boiti-Leon-Pempinelli system is derived first.

• 借助于Painlev B cklund变换和多线性变量分离方法 ；求得了 (2 +1)维非线性Boiti Leon Pempinelle系统的一般变量分离解 .
