| 摘 要： | 用可积系统方法给出了4维Minkowski空间R^3,1中具有平行平均曲率向量的正则类时曲面的表示。与类空曲面不同,这些类时曲面由Klein-Gordon方程ωxy＋｜H｜sinhω=0,ωxy-｜H｜coshω=0,ωxy＋1/2｜H｜eω/2=0所决定,表明这类曲面在R3,1中是丰富的。

| Abstract: | In this paper,the time-like surface with parallel mean curvature vector in 4-dimensional Minkowski space R3,1 is expressed by means of integrable system.Being different from space-like surface,the time-like surface is determined by a kind of Klein-Gordon equations：ωxy＋｜H｜sinhω=0,ωxy-｜H｜coshω=0,ωxy＋1/2｜H｜eω/2=0.It shows that the time-like surface is abundant in R3,1. |
