Meanwhile Donald Michie had been plucked from the Testery, and Jack Good from Hut 8, to work as Newman's first staff on a very exciting development of the Fish analysis.

在這個時期,唐納德·米奇離開了他的部門,傑克·古德也離開了8號營房,他們作爲紐曼的第一批員工,開始進行一項非常刺激的關於魚機的工作。

Donald Michie had continued to work on refinements of the Turingismus method, reporting informally to Alan on their progress—advances reflected in the fact that at the beginning of 1943 a proportion of the Fish signals were being read regularly and with little delay.

唐納德·米奇在研究改進"圖靈方法",他時常會向艾倫報告進展,在1943年初,他們已經能夠定期地、短滯後地破譯一部分魚機信號。

The Turing theory of statistics, with its formalisation of 'likeliness' and 'weight of evidence', and with its 'sequential analysis' idea, were also playing a general part in the Fish work, in which it found greater application than in the Enigma methods.

圖靈的統計理論,包括概率、證據權重以及序列分析,在魚機研究中起着全局性的、比在謎機研究中更深遠的作用。

But by the spring of 1943, Newman's ideas for mechanisation had begun to bear fruit.

到了1943年春天,紐曼的機械化想法也有了成果。

Here the new developments with electronic technology, in which the crucial steps had been taken while Alan was in America, were in themselves very significant.

當時艾倫還在美國,而這邊的電子科技也有了新的發展,這對他們來說,有着不一般的意義。

The Post Office engineers had been able to install a first electronic counting machine in Hut F, where Newman and his two assistants worked, in about April 1943. This and its successors were called the 'Robinsons'.

大約在1943年4月,在紐曼和兩位助手工作的F營房,郵政工程師們組裝了第一臺電子計數器。這臺機器和它的後續型號,被稱爲羅賓遜機注。

Although they had overcome some of the engineering problems associated with passing paper tape very rapidly through an electronic counter, these 'Robinsons' still suffered from many defects.

他們依靠一些早期論文,解決了一些工程上的困難,但是這些羅賓遜機仍有很多問題,

They were prone to catch fire; the paper tapes were always breaking; and the counts were unreliable.

比如說容易着火,紙帶經常撕壞,而且計數也不太穩定,

This was because the slower parts of the counting process were performed by the old relays, and these produced an electrical interference effect upon the electronic components.

因爲老式的繼電器會產生電子干擾。

But the fundamental technological problem was that of synchronising the ingestion of the two separate paper tapes demanded by the method.

最根本的技術問題是,這種方法要求兩條紙帶完美同步。

For all these reasons, the Robinsons proved too unreliable and too slow for effective cryptanalytic use. They were employed only for research purposes.

因爲這些問題,羅賓遜機對於實際的破譯工作來說,既不可靠又太慢了,所以它們只是用於研究目的。

There was also another fundamental difficulty, not so much physical as logical, which made the machine method too slow.

此外還有一個流程上的困難,如果把這種機器應用於密碼分析,

In using it for the cryptanalytic process, the operator would constantly have to produce fresh tapes, resorting for this purpose to an6 'auxiliary machine that was used to produce the tapes which formed one of the two inputs to the Heath Robinson.'

就需要源源不斷地給它供應紙帶,以至於必須專門再給它製造一臺輔助機器,以達到所需的紙帶生產速度。
