差分机：休斯顿，我们有一个问题…
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 a 19th century mechanically drivenapparatus invented by Charles Babbage for his Difference Engine.
巴贝奇设想能有一种更精确、解放人力的方法来计算这些表，而他的差分机就是这个解决之道。
Babbage envisioned a more accurate, labor-saving way of making such tables, and his Difference Engine was the result.
虽然花了150年来完成，差分机2号工作得完全符合巴贝奇所料想，计算——甚至打印出一张一张超高精度的表。
Although it took 150 years to complete, the Difference Engine No. 2 works exactly as Babbage planned, computing - and even printing - table after table of super-accurate data.
最受装置收藏家推崇的设备之一，CURTA计算器是一台现代差分机——一台能进行高精度计算的全机械结构计算器。
One of the devices most prized by gadget collectors, the Curta Calculator is a modern Difference Engine - an entirely mechanical calculating machine capable of great precision.
Lovelace女士和Babbage先生确曾有过合作，但是他们不幸的由于缺乏内置排水管、猴子和差分机而未达建筑规格。
Lady Lovelace and Mr Babbage did collaborate, but their work together unfortunately fell short of incorporating sewers, monkeys and difference engines the size of buildings.
事实上，它工作原理与巴贝奇的差分机相似，不同之处在于它的数字排列在圆柱形的外表面上而不是向织布机架那样水平分布。
In fact, it works much like Babbage's Difference engine, except that its digits are arrayed along the outer surface of a cylinder instead of horizontally along a loom-like rack.
知不知道在上半19世纪，他试图发明一种叫做“差分机”的东西，这是一种机械计算器，可以进行多种不同系列的数字运算？
Who attempted to build something called a "Difference Engine" during the first half of the nineteenth-century, a kind of mechanical calculator designed to compute various sets of Numbers?
首先分析了热烧结矿筛分机(简称热矿筛)筛板使用寿命短的主要原因是由于筛板材质高温硬度低、高温耐磨性差。
It is analyzed the main reason that hot mineral screen plate has short service life, it is because that screen plate had low high temperature hardness and low high temperature wear-resistance.
