感恩!
今天考完出來放狗 鑑定畫的那篇跟JJ裡的英文參考資料相似度非常高 A new study shows how sound waves can detect adozen different inorganic pigments using Fourier-transform photoacousticinfrared (PAIR) spectroscopy (which makes use of signal processing functionsdeveloped by French physicist Joseph Fourier). The process is based in part onan 1880 discovery by Alexander Graham Bell, who demonstrated that shining amodulated beam of light onto an object could create a subtle acoustic wave.
Q: 有關Alexander Graham Bell 這個人何者正確? 1.他是第一個用microphone檢測還是怎樣acoustic wave的(文章內有提到microphone) 2.noted a phenomenon 後來被 PAIR 所應用 (見上面) 其他失意... 小糾結選2...
Q:關於pigment何者正確? 我選新方法對pigment cause little or no damage 但其他選項看起來也很對...上考場仔細看看 |
