雙語暢銷書《艾倫圖靈傳》第8章:水銀延時線(10)
But he considerably amplified this idea in a talk given a year later in February 1947, in words which explained the origin of the ACE as he himself perceived it:
Some years ago I was researching on what might now be described as an investigation of the theoretical possibilities and limitations of digital computing machines.
幾年前，我在研究數字計算機器的理論可能性和侷限性，I considered a type of machine which had a central mechanism and an infinite memory which was contained on an infinite tape.
我考慮了一種機器，有核心的機制和無限的存儲容量，也就是帶有無限長的紙帶，
This type of machine appeared to be sufficiently general.
這種機器是通用的。One of my conclusions was that the idea of a 'rule of thumb' process and a 'machine process' were synonymous.
我的一個結論是，"只基於記憶的過程"和"機械的過程"是同義的，The expression 'machine process' of course means one which could be carried out by the type of machine I was considering...
而"機械的過程"顯然可以由我考慮的這種機器來描述……Machines such as the ACE? may be regarded as practical versions of this same type of machine. There is at least a very close analogy.
像ACE這樣的機器，就是上述理論模型的一種實現，至少是一種非常接近的模擬。Digital computing machines all have a central mechanism or control and some very extensive form of memory.
數字計算機器，包括一組核心控制機制，和一組大容量的存儲機制。The memory does not have to be infinite, but it certainly needs to be very large.
存儲容量不一定要無限大，但肯定要非常大。In general the arrangement of the memory on an infinite tape is unsatisfactory in a practical machine,
像無限長的紙帶這樣的設計，在實際實現中是不可取的，because of the large amount of time which is liable to be spent in shifting up and down the tape to reach the point at which a particular piece of information required at the moment is stored.
因爲這需要浪費大量的時間來反覆移動紙帶，才能在每個時刻取出需要的信息。
