COMPARATIVE ANALYSIS OF TWO KINDS OF GEOMETRICAL SCHEMES FOR DEFINITION OF BRIGHTNESS

Zhu Peiping1)\ \ Pei Yongxiang2)\ \ Liu Chuxiang2)\ \ Zhu Hengjiang2)( 1) SR Laboratory of Institute of High Energy Physics, Chinese Academy of Sciences, Beijing, 100039, China; 2) Department of Physics, Xinjiang Normal Univers  
The definition and expression of brightness in current textbooks are nearly the same, but there are two different kinds of geometrical schemes used. Through the comparative analysis between the two kinds of schemes, it is pointed out that one of them cannot express the brightness definition accurately and figuratively.
