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

像一样，这台器太超前了，并没有完全建成。

In fact, before computers were even built, she made mathematical proofs that can be characterized as the earliest computer programs for a machine called the difference engine and then the analytical engine.

实际上 早在计算发明出来之前，她就先后为和析做了数学证明，这个可以说是最早计算程序了。

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

如果没有擎，我们就不会有今天你们看到这台电脑。

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

他对这些器迷恋激发了他与 Ada Lovelace 一起设计擎。

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

但更重要是，在建造期间 Charles Babbage想象了一个更复杂器 - 析。

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

不像，以及莱布尼茨乘法器和所有其他以前计算设备-析是一台" 通用计算" 。

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草稿建成了一个 而且它能正常使用！

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年开始建造并在接下来二十年里，试图制造和组装25000个零件 这些零件总重接近15吨。

English mathematician Ada Lovelace wrote hypothetical programs for the Analytical Engine, saying, " A new, a vast, and a powerful language is developed for the future use of analysis" . For her work, Ada is often considered the world's first programmer.

英国数学家Ada Lovelace为编写了假想程序，这被称作，" 这是一门为未来析之用一个全新庞大强有效语言" 因为她成果，Ada经常被认为是世界上第一位程序员。

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

很明显，有一位教授给你打了。

The results are processed by another PET called differential privacy.

结果由另一种称为隐私隐私增强术进行处理。

That's why Chronosphere is on a mission to help you take back control with Differential Diagnosis, a new distributed tracing feature that takes the guesswork out of troubleshooting.

这就是为什么Chronosphere致力于通过诊断（Differential Diagnosis）帮助您重新掌控全局。诊断是一项全新布式追踪功能，它消除了故障排除中猜测环节。

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。

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。

The ANOVA table has the following basic form.

方析表具有以下基本形式。

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

我想你应该明白了方析整个来源。

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

Charles Babbage提出了一种称为新型械装置这是一个可以近似多项式更加复杂器。

The results are then analyzed using one of several methods, e.g., the basic EMP (Evaluating the Measurement Process) study or ANOVA.

然后使用多种方法之一对结果进行析，例如基本 EMP（评估测量过程）研究或方析。

And hopefully, just going through those calculations will give you an intuitive sense of what the analysis of variance is all about.

希望这些计算能让你直观地理解方析到底是什么。

First, as shown in Figure 6, the finite difference method is carried out for tunnels and other elements.

首先，如图 6 所示，对隧道和其他单元进行有限法。
