struct node 36 4.3501117E-4,92.00395 slave x y 24什么意思

struct node 36 4.3501117E-4,92.00395 slave x y 24
这个命令是什么意思？这里的slave是什么意思？
手册上这样讲的，
slave <x><y> m
This option sets the slave condition of node n to node m in the x- and/or y-direction. If
neither x nor y is specified, both directions are “slaved”; the rotational degree-of-freedom cannot be slaved. Note that the stiffness assigned to slaved nodes will still influence the critical timestep. Thus, the modulus may be reduced, to increase the timestep for slaved nodes.
但是看不懂，麻烦给讲解一下，
