用法和例句

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

本文对三维Minkowski空间R~(2,1)中具有性质K-2mH+m~2-l~2=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Bcklund变换。

This paper generalizes the classical Backlund theorem on time like surfaces with constant Gaussian curvature (CGC) K=1 in R 2,1 to the surfaces with K=1 in R 2,1 by a time like line congruence, and shows how starting from a given K=1 surface to construct an entire hierarchy of new ones.

通过类时线汇把经典 Backlund理论推广到三维 Minkowski空间 R2 ,1中具有常高斯曲率 K =1的类时曲面的情形 ,并且从已知的具有常高斯曲率 K =1的类时曲面出发 ,利用 Backlund变换构造了一个新的具有常高斯曲率 K=1的类时曲面 。
