He discusses how biological cells perform reliable computation with unreliable components and noise (which refers to random variations in signals - whether electronic or genetic).
The advantages of this process, compared with biological ones, are reduction of noise, less space demand and suitable use in urban areas.
本工艺与生化法相比的最大特点是：占地面积小，耗电量小，减少了噪音污染，尤其适合市区内采用。
