放大比率 meaning in English
amplification ratio
magnification ratio
Examples
- The magnification of any telescope can be changed very easily by changing the eyepiece . even for the largest telescopes , the magnification is seldom over 500 , usually between 100 - 200 . thus , large telescopes do not magnify more , they only show brighter and sharper images
其实大望远镜并不是把天体放得更大，而只是提供一个较光和较清晰的影像罢了倍率是物体视大小的放大比率，例如一个原本视角直径为1角秒的物体，若放大后的视大小为30角秒，那么倍率便是30倍。
