French-English translations for concentrique

concentricIt was then that concentric circles were being spoken of for the first time. C' est à ce moment-là qu' on a parlé pour la première fois de cercles concentriques. Too many parallel concentric circles create a system which is difficult to supervise. L'accumulation de cercles concentriques finit par rendre le système difficilement intelligible. We must therefore see the Union as a ring of concentric circles which are interconnected. Nous devons donc penser à une Union en anneaux concentriques, non imperméables entre eux.
