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

像差分机一样，机器太超前了，并没有完全建成。

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

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

如果没有差分引擎，我们就不会有今天你们看到的脑。

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

然而，在1991年 历史学家根据Charles Babbage的草稿建成了一个差分机 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提出了一种称差分机的新型机械装置是一个可以近似多项式的更加复杂的机器。

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

很，有一位教授给你打了差分。

The ANOVA table has the following basic form.

方差分析表具有以下基本形式。

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

但更重要的是，在差分机的建造期间 Charles Babbage想象了一个更复杂的机器 - 分析机。

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

知道吗 我知道丁沃尔老师何会给我一个差分。

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

了解决节理处不连续变形的问题，采用了有限差分法。

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

而且我认您了解整个方差分析的来源。

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

那么，方差分析法下的测量系统是如何构成可接受的呢？

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

RG 和 RG 差分， 本质上是惯性矩和最大惯性矩与最小惯性矩之间的差。

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 也他的差分机设计了一，那是在 1820 年代！

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

方差分析 (ANOVA) 是一种检查哪些变异来源对结果有重大影响的技术。

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

然而， 方差分析方法允许您估计分量的方差。

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

第六列是方差分析中每个来源的总方差百分比（表 4）。
