And subtractive techniques from the silicon industry can't do that very well.

而硅产业消减技术无法胜任此工作。

At least, it does if you use traditional " subtractive" manufacturing techniques like cutting and drilling.

即使不考虑体积及成本情况下，传‘比相减式'加工流程技术也能完成这些工作，比如切割，机钻等。

So the 1952 NC mill was subtractive.

- 所以 1952 年数控床是减材。

It's a slow process of subtractive and additive sculpting until you start to create a bit of a character.

这是一个逐步减去和添加雕过程，直到你造出一些角色特征。

These are different colour models, where RGB is “additive” meaning the mixing of different lights of colour create new colours-while the other two are “subtractive” models and absorb different wavelengths of light.

这些是不同颜色模型，其中红绿蓝三原色是“相加模型”，它意味着不同颜色光混合创造新颜色，而另外两个是“相减模型”并且吸收不同波长光。

Most printers print in CMYK, cyan, magenta, yellow, and black, which is subtractive, meaning they start from white and layer colored ink on on a scale of 0 to 100, getting closer to black the more of each it lays down.

大多数打印机使用CMYK（青色、洋红色、黄色和黑色）进行打印，这是一种减法模式，意味着它们从白色，在0到100范围内逐层叠加彩色墨水，每种颜色叠加得越多，就越接近黑色。
