His fascination with these machines inspired him to design the difference engine with Ada Lovelace.

他对这些机器迷恋激发了他与 Ada Lovelace 一起设计引擎。

Like the Difference Engine, it was ahead of its time, and was never fully constructed.

像机一样，这台机器太超前了，并没有完全建成。

And without the difference engine, we wouldn't have computers like the one that you're watching me on today.

如果没有引擎，我们就不会有今天你们看到这台电脑。

But, in 1991, historians finished constructing a Difference Engine based on Babbage's drawings and writings - and it worked!

然而，1991年 历史学家根Charles Babbage稿建成了一个机 而且它能正常使用！

Charles Babbage proposed a new mechanical device called the Difference Engine, a much more complex machine that could approximate polynomials.

Charles Babbage提出了一种称为机新机械装置这是一个可以近似多项式更加复杂机器。

But more importantly, during construction of the Difference Engine, Babbage imagined an even more complex machine - the Analytical Engine.

但更重要是，机建造期间 Charles Babbage想象了一个更复杂机器 - 析机。

There's a professor, obviously, who gave you the bad grade.

很明显，有一位教授给你打了。

You know, I know why Dingwall gave me a bad grade.

知道吗 我知道丁沃尔老师为何会给我一个。

So, what makes an acceptable measurement system under the ANOVA method?

那么，方析法下测量系统是如何构成可接受呢？

The ANOVA table has the following basic form.

方析表具有以下基本形式。

To address the issue of discontinuous deformation at joints, the finite difference method is employed.

为了解决节理处不连续变形问题，采用了有限法。

And I think you get a sense of where this whole analysis of variance is coming from.

而且我认为您了解整个方析来源。

RG, and RG differential, essentially the moment of inertia and difference between maximum and minimum moments of inertia.

RG 和 RG ， 本质上是惯性矩和最大惯性矩与最小惯性矩之间。

Paper printers were so useful that even Babbage designed one for his Difference Engine, and that was in the 1820s!

纸质打印机非常有用，甚至 Babbage 也为他机设计了一台，那是 1820 年代！

Analysis of variance (ANOVA) is a technique that examines what sources of variation have a significant impact on the results.

方析 (ANOVA) 是一种检查哪些变异来源对结果有重大影响技术。

The sixth column is the % of total variance for each source from the ANOVA analysis (Table4).

第六列是方析中每个来源总方百比（表 4）。

The ANOVA method, however, allows you to estimate the variance of the components.

然而， 方析方法允许您估计量方。

Babbage started construction in 1823, and over the next two decades, tried to fabricate and assemble the 25,000 components, collectively weighing around 15 tons.

Charles Babbage于1823年开始建造机并接下来二十年里，试图制造和组装25000个零件 这些零件总重接近15吨。

It means that the more segments rings will suffer differential settlement.

这意味着 Segments 越多，环圈将遭受沉降。

Unlike the Difference Engine, Step Reckoner and all other computational devices before it - the Analytical Engine was a " general purpose computer" .

不像机，以及莱布尼茨乘法器和所有其他以前计算设备-析机是一台" 通用计算机" 。
