差分机

1991年英国科学家根据巴贝奇的设计说明书制造了差分机2（能进行三十一位数的精确运算）。

In 1991 British scientists Built Difference Engine No. 2 ( accurate to 31 digits ) to Babbage 's specifications .

世界上第一台计算机的打印机是一种19世纪的机械驱动装置发明的查尔斯巴贝奇的差分机。

Theworld 's first computer printer was a19th century mechanically drivenapparatus invented by Charles Babbage for his Difference Engine .

他坚持认为，相比于差分机项目，ACE应该拥有绝对的优先权。

He urged that the machine should have every priority over the existing proposal for the construction of a large differential analyser .

他们在和平时期也是这样，比如在30年代初就抢先研制模拟差分机。

just as they were ahead in the analogue differential analyser of the earlier 1930s .

第四组的工作是围绕哈特里差分机的，这是曼彻斯特那段时光的延续。

A fourth section consisted of the staff of the Hartree differential analyser , and remained for the time being at Manchester .

这并不是新思想，威廉姆斯已经为曼彻斯特差分机制造了这么一个东西。

This was not a new idea , for F.C. Williams had built just such a thing for the old Manchester differential analyser .

沃默斯利作为联合作者，在1937年与哈特里共同发表了一篇论文，关于差分机在偏微分方程中的应用。

Womersley had appeared as joint author with Hartree of a 1937 paper on the application of the differential analyser to partial differential equations .

其中一个是美国工程师范内瓦·布什1930年在麻省理工学院设计的差分机，

One of these was the ' differential analyser ' that the American engineer Vannevar Bush had designed at the Massachusetts Institute of Technology in 1930 .

碰巧的是，布莱克特在战争之前就认识威廉姆斯，当时他们一起为了差分机，合作研究自动曲线仪。

It so happened that Blackett knew F.C. Williams from before the war , when they had collaborated on an automatic curve-tracer for the differential analyser .

哈特里在曼彻斯特大学做过差分机，他对计算机很感兴趣，并且也参与了很多战时的科研项目。

Hartree , with his differential analyser at Manchester University , already had an interest in computing machinery , and had a finger in many wartime scientific projects .

他不但学习数学和逻辑，同时还学习神经学，并且将差分机看作实现思想机器的第一步。

he had studied neurology as well as mathematics and logic , and had seen his work on the differential analyser as a first step towards a thinking machine .

这些都反映在沃默斯利1944年12月的报告中。他的报告强调要建造一个大型差分机，他看到了电子技术的高速性，

Such knowledge was reflected in Womersley 's report in December 1944 , which , though it placed emphasis upon building a large differential analyser , remarked on the speed of electronics ,

紧接着，剑桥也建造了一个差分机，1937年，数学系还批准了一个新的实验室用来安置它，

This in turn had been followed by the commissioning of another differential analyser at Cambridge , where in 1937 the mathematical faculty had sanctioned a new Mathematical Laboratory to house it .

并且谈到了“分析引擎，差分机，以及其它现有的或今后将会发明的机器，必将有伟大的前景，但目前还无法预测它明确的发展方向”。

only made mention of ' analytical engines , including the differential analyser and other machines both existing and awaiting invention ... it is certain that this field is capable of great developments , but it is more difficult to predict in what directions they will lie . '
