1.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。

2.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，传统‘对比相减'加工流程技术也能完成这些工作，比如切割，机钻等。

3.So the 1952 NC mill was subtractive.

- 所以 1952 控铣床是减材。机翻

4.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。
