证明了具有循环边群的自由群有限图的Jrl是子群可分的，除非Jrl有一个非平凡元素g使得gn“Vgm，其中ni = ±m.从表象中很容易判断这种共轭性是否存在。
It is shown that Jrl of a finite graph of free groups with cyclic edge groups is subgroup separable unless Jrl has a non-trivial element g such that gn "V gm with n i= ±m. It is easy to decide from the presentation if such a conjugacy exists.
