decline 作为婉拒的意思的名词形式是declining ，是动名词。例句：Her declining our offer of a job means we will have to find another person to fill the vacancy.The Lees' declining our invitation will result in the meeting being two short of the quorum. If, instead of declining our invitation, you have decided to accept it, then we hope that you will find much to enjoy in our annual get-together.另一方面，declination 的意思是 “拒绝“ （不是 ”婉拒“），语气比较”硬“，意思和 declining 有小小的区别，例：It's important to be polite when writing a letter of declination to a job offer.
