  1. We have to use some other methods to measure the luminosity or equivalently the absolute magnitude of the cepheid variable. since we can readily measure the apparent magnitude of a cepheid variable, to measure the luminosity means measuring the distance. we use some distance measurement methods, for example, parallax, to determine the relation

    要弄清這個關系,我們要知道不同造父變星的光度和光變周期數據,量度光變周期當然不是問題,但要得知一顆恆星的光度,我們首先要得知它的距離,這時便須藉助好像視差法等其他量度天體距離的方法。
  2. This is the apparent magnitude of an object at some standard distance from us. this standard distance is chosen to be about 32 light years 10 parsecs, see below

    絕對星等是恆星距離為約32光年或10秒差距請參閱下一節時的星等。
  3. Apparent zenith distance

    視天頂距
  4. We found that the luminosities of type i supernovae are about the same. therefore, we can compute the distance to a galaxy by measuring the apparent brightness of a type i supernova in that galaxy, if we can find one

    科學家發現原來所有這種超新星爆發的光度都是差不多的,所以我們只要找到這種超新星,便可以由它的視亮度推算出它和地球的距離,從而得知它所處身星系的距離。
  5. The limitations of current video technology, however, mean that the quality of the visual experience of the real world is significantly decreased, essentially to the level of the synthesized graphics, with everything focusing at the same apparent distance

    然而,現有視訊技術仍有其限制,它所呈現的真實世界的視覺品質還相當差,甚至會降到合成圖像的水準,因為虛擬和實體的所有視覺焦點都在相同距離上。
  6. If its distance from the eye is halved, its apparent size is doubled.

    同一物體,與眼的距離減半,相對大小就大一倍。
  7. Despite continuous upgrading and modernization, it became apparent that hong kong needed a brand new airport, ideally, situated at some distance from built - up areas and served by a fast, efficient, public transport system

    盡管啟德機場不斷進行改善和更新工程,香港顯然需要一個全新的機場。理想的地點須離開市中心,並有快捷方便的公共交通接駁系統。
  8. Poor visibility to satellites may cause the calculated position to wonder around, increasing the apparent traveled distance

    較差收星信號可能引起計算位置的游離,從而增加了顯示的旅行距離。
  9. Objects look bigger when they are closer to us. if the distance between an object and the observer is halved, the apparent size of the object will be doubled

    物件離我們越近,看來便會越大當物體和我們的距離減半,物體看來便會大了一倍。
  10. But due to the existence of the fault resistance, the branch current, the zero sequence mutual coupling and so on, the apparent impedances and protection scope of distance protection will change, thereby affecting the performance of distance protection and the safety operation of power system

    然而,由於過渡電阻、分支電流和零序互感等因素的影響,會改變距離保護測量阻抗的大小,造成距離保護動作范圍的擴大與縮小,從而影響距離保護的性能,威脅電力系統的安全運行。
