  • energy : n. 1. 干勁，活力。2. （語言、行為等的）生動。3. 〈pl. 〉 （個人的）精力；能力。4. 【物理學】能，能量。
  • photon : n. 1. 【物理學】光子。2. 【醫學】見光度〈網膜照明單位〉。
  1. One of the key techniques is the detection of near infrared ( 1310nm and 1550nm ). because the quantum key is transmitted by one photon, and 1310nm and 1550nm infrared are the lost loss wavelength in fiber. we can detect the visible light now, but it is difficult to detect the near infrared because of its low energy

    量子通信的關鍵技術之一就是紅外（ 1310nm 、 1550nm ）單光子探測，這是因為光量子密鑰傳輸是採用單個光子來實現的， 1 . 3微米和1 . 5微米是現在所使用的光纖通信中損耗最小的波長，現有成熟的單光子探測器工作波長都是在可見光波段，而紅外光子因為能量小，信號非常微弱，極易被噪聲淹沒，因而非常難探測到。
  2. X and gamma reference radiation for calibrating dosemeters and doserate meters and for determining their response as a function of photon energy - part 4 : calibration of area and personal dosimeters in low energy x reference radiation fields

    校準劑量儀和劑量率儀及確定其光子能量響應的和參考輻射.第4部分:低能x參考輻射場中場所劑量計和個人劑量計的校準
  3. X and gamma reference radiation for calibrating dosemeters and doserate meters and for determining their response as a function of photon energy - calibration of area and personal dosemeters in low energy x reference radiation fields

    校準劑量儀和劑量率儀及確定其光子能量響應的和參考輻射.低能x參考輻射場中場所劑量計和個人劑量計的校準
  4. Low energy photon detector

    低能光子探測器
  5. It takes ten million years for the energy of the original photon to come to the outer part of the sun in the form of thousands of low energy photons in the form of mainly visible light

    ，一顆在核心內產生的光子，需要數千萬年才能以數千顆低能量主要是可見光的光子的形式到達太陽表面。
