“against“”在外贸英语中译做“凭借，依靠“”的意思，对吗？请看例句： For payment,we require 100% value,confirmed and irrevocable letter of credit with partial shipment and transhipment allowed clause,available by draft at sight,payable against surrendering the full set of shipping documents to the negotiating bank here. 我们要求用100%金额的、保兑的、不可撤销的信用证，并规定允许转船和分批装运，凭汇票向议付行交单即期付款。 谢谢各位~~ :D
