B、是消费者从消费商品中所获得的总的满足程度
C、边际效用的概念是序数效用论提出来的
D、边际效用可以用符号TU代表
B、边际效用递减规律要求其他商品的消费数量保持不变,如果突破这个限制条件边际效用也一定递减
C、正是因为边际效用递减,所以人们往往希望消费的商品种类是多样化的
D、正是因为边际效用递减,所以人们往往希望消费的商品种类是单一的
A.边际效用是递减的
B.从数学的意义上看,边际效用就是总效用函数的斜率
C.一般来说,总效用(TU)取决于消费数量的多少

A、They understood that many things in the world are "fixed," but in art, we can make things alive by giving them some movement and by providing several perspectives.
B、Traditionally in China everyone is against monotony and routine, and in art one expresses this rebellious attitude towards monotony and routine by having more than one perspective.
C、They believed that Dao gave life to ten thousand things, so to understand Dao we need to analyze those many things and in art we can do that by having several perspectives.
D、Chinese seek to find dynamic Dao in the movements. Thus an artist tries to express Dao dynamics by constantly changing the point of perspective in the painting.
