雙語暢銷書《艾倫圖靈傳》第6章:連接兩個世界(6)
Most of his time, however, was spent in one particular 'cell' which had the responsibility of trying to crack speech encipherment systems which had been proposed.
He made an impression from the start, for within an hour of arrival he had solved a problem.
艾倫剛坐下來一個小時，就解決了一個問題，因此讓同行們大爲驚歎。It involved a scrambling system in which time segments were permuted, by means of nine magnetic heads simultaneously reading a magnetic tape.
這是一個擾亂式的加密系統，它用9個磁頭同時對磁帶進行讀寫，從而將時間片段打亂順序。
'That ought to give you 945 codes,' said Alan when this was explained, 'It's only 9x7x5x3.'
當他們向艾倫解釋這套系統時，艾倫立刻說："應該有945種組合，就是9×7×5×3而已。"It had taken one of their technicians a week to work it out.
而他們的一位技術人員，花了一週纔算出這個數。For his first week, Alan acquainted himself with all the projects on which they were working, and became particularly keen on taking up one of them himself.
在第一週，艾倫熟悉了他們正在進行的所有項目，並打算承接其中一個項目。This was the challenge presented by an RCA engineer, who had devised a system in which a speech signal would be multiplied by a key signal.
一位工程師提出了一個想法，將語音信號乘上一個密鑰信號。It presented quite an unusual problem.
這是一個很不尋常的問題。On 23 January, Alan announced he had begun to think of a way of attacking it, and then he came in after the weekend convinced of its possibilities.
1月23日，艾倫開始思考解決方案，隨後他在週末來到辦公室，確定了該方案的可行性。His idea involved the use of the Vocoder.
他的想法是使用聲碼器。
