  1. Because blue and red are respectively near the frequency of high and low ends of the visible spectrum

    由於藍及紅為可見光譜中頻率最高及最低的兩端，所以在天文學中，我們稱恆星光的
  2. In many stellar disks, observers also have found the spectral signature of silicate emission, indicating that small dust grains on the disk surface have been strongly heated by the stellar radiation

    天文學家也發現了許多恆星氣盤具有矽的發射光譜，表示盤面上的微小塵埃顆粒已被恆星輻射強烈加熱。
  3. This paper describes a new method to select these parameters, including to determine the focus length, relative aperture and field of view of new optical system in design by means of making reference to previous star sensors and their optical systems ; to forecast the acquiring probobility of star sensor in accordance with selected param eters ; to determine the principal design wavelength and spectral coverage by means of integrat ing the spectrum of stars

    本文介紹一種確定光學系統參數的新方法，包括通過參考比較已有星敏感器及其光學系統特性來選取新光學系統焦距、相對孔徑和視場；根據所選取的參數預計星敏感器的捕獲概率；採用綜合恆星光譜方法確定光學系統中心波長和光譜范圍。
  4. Because the photospheric temperature of carbon stars are less than 3000k and the temperature of rich - dust envelope formed by the mass loss is lower, and therefore most of the energy from carbon stars are radiated between 1 to 60um range, in which the vibrational and ro - vibrational bands of many molecules also lies, the study of infrared spectra in this wavelength range is very important to reveal chemical compositions, dust formation process, the atmospheric structure and evolutionary status of stars

    碳星光球的有效溫度不超過3000k ，同時較大的質量損失率形成了富碳的塵埃殼層，以致於它的輻射能量主要集中在1 ? 60 m的紅外波段上，並且許多分子的轉動振動能譜也集中在紅外，因此在紅外波段的研究對揭示碳星化學成份及其分佈、塵埃形成過程、恆星大氣結構和演化狀態都有十分重要的意義。
  5. Stars are classified by their spectral lines well before we know that those lines are also related to the temperature. the classes of spectral lines are called the

    早在科學家了解顏色和溫度的關系之前，天文學家早已根據光譜的吸收線把恆星分類，這種分類方式稱為
