difference of level meaning in Chinese

电平差
落差

And since the difference of levels of commitment and obligations between pacs ( a form of civil unions ) and marriage has been reduced by the law , marriage becomes more and more like a religious agreement or something you should try once before you die , no age limit
法国法律的改动使得pacs (共同民事协定)和婚姻的区别越来越小，婚姻越来越只像是一项宗教协议，一件在离开人世前要做的没有年龄限制的事情。
