It is showed that the surface roughness is mainly related with the average grain size and feed per wheel revolution for the brittle materials such as single crystal silicon.

研究结果表明，对于微晶玻璃等脆性材料，其表面粗糙度主要与砂轮的平均磨粒尺寸、砂轮速度、进给量及磨削深度等因素有关。

Thus to survive and prosper in the silicon revolution, it wasn't enough to shun stagnant industries and identify growth ones.

FORBES: Steel Versus Silicon

The silicon revolution that started back then with the personal computer, led to the Internet in the 1990s and broadband in the 2000s.

FORBES: Stocks Edging Closer To Financial Cliff

But software is what differentiated Apple from the get-go, software built on a silicon computing revolution developed by others.
