雙語暢銷書《艾倫圖靈傳》第8章:水銀延時線(4)
This was an attractively cheap solution within the existing technology, and had been provisionally adopted in the Draft Report on the EDVAC.
In this September 1945 period, they tried out the principle in the Hanslope hut.
1945年9月，圖靈他們在漢斯洛普對該原理進行了實驗。Don Bayley rigged up a cardboard tube, eight inches across and the whole ten feet of the hut in length.
唐·貝利用硬紙板做了一個管道，直徑8英寸，長度10英尺（他們的房間只能容下10英尺）。
They connected the amplifier to a microphone at one end of the tube and a loudspeaker at the other.
圖靈做了一個超級靈敏的擴音器，把擴音器的話筒連到管道的一端，把喇叭連到另一端。The idea was simply to get a feel for the problem by recycling a sound wave in air on the delay line principle, clapping at one end and hoping to set up a hundred artificial echoes thereafter.
然後他們在一端拍手，讓聲波在延線中循環，以此來探究這個原理。They did not get it to work before Alan left Hanslope to take up his NPL post, which officially began on 1 October 1945.
1945年10月1日，當圖靈離開漢斯洛普，去國家物理實驗室就職時，這項實驗仍然沒有成功。But it meant that he arrived full of ideas both logical and physical, and was far from being the pure mathematician of 1938.
但是這至少意味着，當圖靈到達新的崗位時，腦海中已經有了許多關於實踐的想法，他不再是1938年的那位純數學家了。In setting up the new Mathematics Division, Womersley had been able to recruit from the experts in the field of numerical computation, as it had been developed for the war effort.
在組建新的數學部門的過程中，沃默斯利招募了一些數字計算領域的專家，這個領域在戰爭中取得了巨大進展。His division took over the highly regarded Admiralty Computing Service as the nucleus of what was the most high-powered group in the western world, the rival being the American equivalent at the National Bureau of Standards.
他的部門，取代了聲望很高的海軍計算部，成爲西方世界最有力量的組織核心，競爭對手是美國國家標準局的相應部門。
