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

像差分一样，这台器太超前了，并没有完全建成。

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 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.

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

纸质打印非常有用，甚至 Babbage 也他的差分设计了一台，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。
