--------an increase of this order of magnitude-------
order是顺序、次数的意思,引申出等级的意思,在数学上表示次、级、阶的意思,(one/an 2, 3, ...) order(s) of magnitude 是几个数量级的意思,但是在非数学的语境中,an increase of this (=so) order of magnitude 的意思是 如此巨大的增长
------- The star varies in brightness by about three magnitudes. --------- 这颗恒星的亮度是变化的,变化的幅度可达三个星等(表示天体亮度的单位)
vary in ... 在某方面的变化,这是介词in的一个用法; 介词by 后接数量短语用来表示数量的大小、变化的比例、幅度等等
