镀金 dùjīn
(1) [water-gild]∶附金于[金属表面],其法是先用金汞薄薄地镀上一层,随后加热使汞挥发
(2) [gold-plate]∶用金来电镀
(3) [get gilded;formerly said of students who went abroad to study in order to enhance their social status]∶比喻为虚名而到某地进行所谓的深造或锻炼
以薄层的黄金镀在器物的表面上。
讥讽人到某种环境去深造或锻练后,洋洋得意,自恃高人一等,而实际上只有虚名,并无真才实学。
如:「出国后应脚踏实地的求学,否则即使拿了学位,空得镀金虚名,也是枉然。」
