雙語暢銷書《艾倫圖靈傳》第5章:解謎接力賽(91)

Some were even more ironic:

還有一些更諷刺的：

"22 April; deciphered 19 May"

"4月22日信息，5月19日破譯"

The U boat campaign makes it necessary to restrict severely the reading of signals by unauthorised persons.

因潛艇戰役，必須嚴禁未經許可的人員讀取通信信號。

Once again I forbid all authorities who have not express orders from the operations division or the Admiral commanding U boats to tune in on the operational U boat wave.

我再次重申，所有未接到行動部門或海軍潛艇指揮部的命令者，嚴禁接收潛艇行動頻道。

I shall in future consider all transgressions of this order as a criminal act endangering national security.

若違反此命令，將被視爲危害國家安全的犯罪行爲。

Weeks-old material still had value in building up a knowledge of the system, but of course it was of desperate importance that the time-lag be reduced.

雖然有幾個星期的滯後，但這些信息對於積累破解經驗而言，仍然是很有價值的。當然，減少滯後也是極爲重要的。

By the end of May 1941 they were able to bring down the time to as little as a day.

1941年5月末，他們已經能把滯後時間縮短到一天。

One message that was deciphered within a week read:

有一條信息在一週內被破譯：

"19 May; deciphered 25 May"

"5月19日信號，5月25日破譯"

From: Admiral commanding U boats

自：海軍潛艇指揮部

To: U 94 and U 556
