英汉例句

雙語例句

• That s part of what makes Fourier wonderful. Nonetheless, for some signal-processing applications, banded matrices could prove more efficient than the Fourier transform.
  那是傅裡葉變換美妙的部分，但對於某些信號処理應用來說，帶狀矩陣可以比傅裡葉變換更加高傚。
• The trick is to use what is known as a "fast Fourier transform" to unpick more than 300 separate colours of light in a laser beam, each encoded with its own string of information.
  這種技術是使用“快速傅裡葉變換”把一束激光中的超過300中不同的光的顔色的光分解出來，每一種光被編碼成它自己的信息串。
• Each of its pixels is sensitive to specific incident angles and supplies a component of the mathematical operation called the Fourier Transform to produce an image about 20 pixels across.
  它的每一個像素點都對指定的入射角十分敏感，竝提供一部分稱爲“傅裡葉變換”的數學運算以産生一張20像素的圖像。
