雙語暢銷書《艾倫圖靈傳》第8章:水銀延時線(95)
At the same time, Alan managed to make a few experiments of his own in the cellar of Teddington Hall, the Mathematics Division building, and explained some electronics to Mike Woodger.
He had devised circuits to transmit and receive pulses along a delay line, and a system to probe the circuit so as to examine the shape of the pulse on an oscilloscope.
圖靈設計了一個電路，用來傳輸和接收延遲線上的脈衝，還設計一個系統，用來檢測示波器上的脈衝形狀。The NPL had nothing in the way of a machine to do this elementary engineering task, so, as at Hanslope, he had made one for himself.
國家物理實驗室沒有做這種實驗的設備，於是就像在漢斯洛普一樣，圖靈自己造出了這些設備。
The whole thing involved mounting four or five valves on a breadboard, and no more. He had no delay line to work with.
他在麪包板上焊了四、五個真空管，然後就扔在那裏，因爲他沒有延遲線可以用。A little later, coming back from lunch, he spotted a drainpipe lying in the long grass, and had someone help carry it back for him to try out as an air delay line.
過了一會，吃完午飯後，圖靈在草地裏找了一根排水管，並叫人幫忙把它扛回來，他準備用這個當成空氣延遲線，以完成他的實驗。Don Bayley and 'Jumbo' Lee came and saw this 'dog's breakfast' of an outfit in March or April 1947.
1947年3月或4月，唐·貝利與"大個兒"李來看望圖靈，Alan took Don for a walk round the grounds and complained bitterly of how he had been thwarted.
圖靈帶着唐圍着草地散步，並愁眉苦臉地抱怨他遇到的挫折和打擊。Alister Watson, philosopher now turned radar expert, visited the NPL on business and heard Alan complain that 'they say I don't understand magnetism!'
哲學家艾利斯特·沃森，後來成了雷達專家，他有一次訪問國家物理實驗室時，聽到圖靈抱怨說"那些人竟然說我不懂磁學！"。Francis Price from Princeton days, whose family lived at Teddington, heard out his acrid comments on how the administration denied him the most standard pieces of equipment for experiment.
圖靈在普林斯頓認識的弗蘭西斯·普萊斯，則聽他說過行政部門拒絕爲他提供最基本的實驗設備。
