Example Sentences:

	1.	Thus , the apparent magnitude is not an intrinsic property of the star 因此，视星等并不足以显示出恒星的内在特质。
	2.	For example , the apparent magnitude of our sun is - 26 . 8 , but its absolute magnitude is just 4 . 8 . the absolute magnitude describes the 例如太阳的视星等为- 26 . 9等，但它的绝对星等只有4 . 8等。
	3.	This greatly simplifies the various analyses , for example , their relative apparent magnitudes are equal to their relative absolute magnitudes 当然，成员星和地球的距离亦会差不多，因此大大简化了对成员星的分析。
	4.	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 绝对星等是恒星距离为约32光年或10秒差距请参阅下一节时的星等。
	5.	Two stars have the same absolute magnitude . one is thousand times farther away than the other . what is the difference in apparent magnitudes ? which magnitude larger 两颗星具有相同的绝对星等，其中的一颗比另一颗距离远1000倍，它们的目视星等有何不同？哪一个的星等数值大？
	6.	The longer the period , the brighter the star is . thus , by measuring the period of a cepheid variable , we know its absolute magnitude , hence , we can tell how far it is away by comparing with its apparent magnitude 所以，只要知道某一造父变星的周期，我们便可得知它的绝对星等，只要和它的视星等作比较，便可以求得它和我们的距离。
	7.	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 要弄清这个关系，我们要知道不同造父变星的光度和光变周期数据，量度光变周期当然不是问题，但要得知一颗恒星的光度，我们首先要得知它的距离，这时便须借助好像视差法等其他量度天体距离的方法。
