雙語暢銷書《艾倫圖靈傳》第8章:水銀延時線(32)
He had learnt from the mushrooming of Bletchley.
He proposed a total of 1400 square feet for the machine and its accessory equipment, and estimated the total capital cost of a machine with two hundred delay lines at 11,200 pounds.
建議使用1400平方英尺的空間來部署該機器及其輔助設備，預計配置200條延遲線，預算成本共計11, 200英磅。Changes would have to be made as they went along, but his plans allowed for that: the main thing was to get started.
實際建造時肯定會有一些變化，但他的計劃已經爲此留出了餘地。這項大工程，現在正式準備啓動了。
His February 1947 talk would expand on how the machine would 'prove its worth', by giving a picture of the operation of the machine.
1947年2月，圖靈在報告中詳述了這臺機器將如何"證明自己的價值"，他描繪了一幅機器運行的場景Let us begin with some problem which has been brought in by a customer.
我們來看看這臺機器如何解決客戶提出的問題。It will first go to the problems preparation section where it is examined to see whether it is in a suitable form and self-consistent, and a very rough computing procedure made out.
首先是任務準備階段，此時要檢查所解問題是否相容，是否具有合適的形式，然後爲其設計一個大概的計算過程。He gave a specific example of a problem, namely the numerical solution of a differential equation involving Bessel functions.
圖靈給出了一個具體問題作爲例子，即貝塞爾函數的差分方程的數值解(This would be a very typical problem arising in applied mathematics and engineering.)
（這是數學和工程中非常典型的問題）。He explained how the instruction table for the Bessel function would be already 'on the shelf', and so would one for the general procedure for solving a differential equation. So
接下來他假設貝塞爾函數的指令表已經"在架子上"準備好了，求解差分方程的一般過程也準備好了，然後：The instructions for the job would therefore consist of a considerable number taken off the shelf together with a few made up specially for the job in question.
計算任務所需的指令，有一些是"架子上"的標準指令，還有一些是爲了該問題而編寫的專用指令。The instruction cards for the standard processes would have already been punched, but the new ones would have to be done separately.
標準指令卡片是現成的，專用指令卡片則需要專門打孔製作。When these had all been assembled and checked they would be taken to the input mechanism, which is simply a Hollerith card feed.
將這些都準備好並檢查過之後，我們把這些卡片輸入機器，這隻需要一個簡單的霍勒瑞斯卡片進給裝置。They would be put into the card hopper and a button pressed to start the cards moving through.
將這些卡片放在進給槽裏，按一個鍵，就可以將其輸入機器。
