According to his rule of thumb, known as Moore’ s law, processing power doubles roughly every two years as smaller transistors are packed ever more tightly onto silicon wafers, boosting performance and reducing costs.

這句話是一個復(fù)合句，"According to his rule of thumb"可看做狀語，"known as Moore’ s law"從結(jié)構(gòu)上講更像是過去分詞做"his rule of thumb"的后置定語；句子主語是"processing power"，謂語"double"，"every two years"是時間狀語，副詞"roughly"也起到狀語的作用修飾前面的動作"double"；"as"引導(dǎo)時間狀語從句，從句主語是"smaller transistors"，謂語是被動語態(tài)"are packed"，"ever more tightly"作狀語，你可將"onto silicon wafers"也當(dāng)成狀語，"boosting performance and reducing costs"為現(xiàn)在分詞作狀語，你可以當(dāng)伴隨也可以當(dāng)因其后果的結(jié)果狀語。

 

 

根據(jù)他的經(jīng)驗法則,也就是著名的摩爾定律, 隨著更小的晶體管越來越緊密地被壓縮到桂片上, 芯片的處理能力大約每兩年可提升一倍, 提高了性能也降低了成本。
