雙語暢銷書《艾倫圖靈傳》第7章:運轉起來(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，他們已經能夠完全掌控德國潛艇的行動，並且還有餘力來研究其它型號的謎機。If they did not need Alan Turing on what had become a routine task.
這些工作都已經成爲常規，不再需要艾倫了。
He had already been introduced to the job of inspecting speech cipher systems, and to the delicate work of Anglo-American liaison.
他被委以檢驗語音系統的任務，以及其它一些英美聯絡工作。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.
現在盟軍面對的問題，就是要從1942年的窄視症和拖延症中恢復過來，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.
他們不允許在1944年再出現那種脫節。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.
對於艾倫·圖靈來說，與解謎接力賽相比，這是一份抑鬱的、讓人打不起精神的工作。但是，這份工作迫切地需要他這樣的專家。After June 1943 the Atlantic war turned dramatically in favour of the Allies, with ship sinkings reduced to tolerable levels.
1943年6月之後，盟軍在大西洋戰場戲劇性地佔據了上風，該時期的擊沉數量已經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'.
回想起來，1943年3月的大西洋戰場是艱難而危險的，而在此之後則可以說，德國潛艇已經被打敗了。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.
但事實上，1943年仍有危機在延續，不是船艦，而是整個體系每天都在被更高級的體系打敗。At last they introduced long-range air patrols to cover the mid-Atlantic gap.
最終，他們引入了遠程空中巡邏，覆蓋整個中大西洋，And the logical advantage held by the U-boats in 1940 had been reversed.
德國潛艇1940年所擁有的邏輯優勢才被徹底顛覆。
