美系的頭蓋的上線和吻部的上線平行，
英系則兩線不平行,吻部向上翹,呈碟形臉，
其實英系根本就不是碟形臉~反而和美系有著很接近的地方。
下面比較一下兩個系的標準要求：
英系標準原文：Viewed in profile, top of skull and top of muzzle lie in two parallel straight lines of equal length divided by a slight, but perceptible stop or break.
意思是：從側面看~頭蓋的上線和吻部的上線是兩條平行等長的直線~~這兩條線由一個輕微的能目測地額段分開來。
美系標準原文In profile view the top of the backskull and the top of the muzzle lie in two approximately parallel, straight planes of equal length, divided by a very slight but perceptible stop or break.
意思是：從側面看~頭蓋的上線和吻部的上線是兩條大至平行等長的直線~~這兩條線由一個非常輕微的能目測地額段分開來。
