重复构造 meaning in Chinese

repeat construct
repetition construct
repetitive construct

In this paper , we give the backlund transformations and discuss its structures to some extent for the integrable discretization of the nls1 " equation : the transformation gives a way to construct solutions to the system ( 1 . 3 ) , and it also does to the equation ( 3 . 1 ) , which contribute to reconstruct solutions to the system ( 1 . 3 )
贝克朗变换给出了一种构造方程( 1 . 3 )解的方法，同时也给出了构造其拉克斯对方程( 3 . 1 )解的方法，这就给我们对方程( 1 . 3 )的解进行重复构造创造了条件。
