本文对三维Minkowski空间R2,1中具有性质K-2mH+m2-l2=0或H=constant的类时曲面定义了一个Darboux线汇,同时得到了相应的B(a)cklund变换.

In this paper, we define a Darboux line congruence about the time-like surfaces, and obtain corresponding B(a)cklund transformation on time-like surfaces with condition K - 2mH + m2-l2 = 0 or H = constant in R2.1.
