摘　　要：利用投射方程法和变量分离法,得到了(3+1)维Burgers系统的变量分离解(包括孤波解、周期波解和有理函数解).根据孤波解和有理函数解,构造出Burgers系统新颖的局域结构,例如瞬内嵌孤子和瞬锥形孤子.With a projective equation method and a variable separation method,new families of variable separation solutions（including solitory wave solutions,periodic wave solutions,and rational function solutions） for（3 ＋ 1）-dimensional Burgers system is derived.Based on a derived solitory wave solution and a rational function solution,we obtain some novel localized structures such as instantaneous embed soliton and instantaneous taper-like soliton.
