双语畅销书《艾伦图灵传》第7章:运转起来(7)
Although the British produced the first working high-speed four-wheel Bombe in June 1943, the Americans produced more and better Bombes after August.
By the end of 1943 they had taken over the U-boat work entirely, and had spare capacity for other Enigma problems.
到了1943年年底，他们已经能够完全掌控德国潜艇的行动，并且还有余力来研究其它型号的谜机。If they did not need Alan Turing on what had become a routine task.
这些工作都已经成为常规，不再需要艾伦了。
He had already been introduced to the job of inspecting speech cipher systems, and to the delicate work of Anglo-American liaison.
他被委以检验语音系统的任务，以及其它一些英美联络工作。The Allies now had the problem of recovering from the delays and narrow vision of 1942, at a time when communications were expanding enormously and growing towards their great climax.
现在盟军面对的问题，就是要从1942年的窄视症和拖延症中恢复过来，通信量正在迅速增加，The times had been out of joint, something they could not afford to allow in the intricate plans for 1944.
他们不允许在1944年再出现那种脱节。For Alan Turing this would be dull and dispiriting work compared with the excitement of the relay race; but it was the job crying out for expert attention.
对于艾伦·图灵来说，与解谜接力赛相比，这是一份抑郁的、让人打不起精神的工作。但是，这份工作迫切地需要他这样的专家。After June 1943 the Atlantic war turned dramatically in favour of the Allies, with ship sinkings reduced to tolerable levels.
1943年6月之后，盟军在大西洋战场戏剧性地占据了上风，该时期的击沉数量已经降低到了可以容忍的水平。In retrospect, March 1943 had seen 'the crisis' of the battle of the Atlantic, and thereafter it could be claimed that 'the U-boat was defeated'.
回想起来，1943年3月的大西洋战场是艰难而危险的，而在此之后则可以说，德国潜艇已经被打败了。But more truly, 1943 saw a continuing state of crisis, one in which it was not the boat but the system that was beaten from day to day by a superior system.
但事实上，1943年仍有危机在延续，不是船舰，而是整个体系每天都在被更高级的体系打败。At last they introduced long-range air patrols to cover the mid-Atlantic gap.
最终，他们引入了远程空中巡逻，覆盖整个中大西洋，And the logical advantage held by the U-boats in 1940 had been reversed.
德国潜艇1940年所拥有的逻辑优势才被彻底颠覆。
