Sealed first-price auction 首价密封拍卖

Sealed first-price auction, also known as a first-price sealed-bid auction (FPSB). In this type of auction all bidders simultaneously submit sealed bids so that no bidder knows the bid of any other participant. The highest bidder pays the price they submitted.
首价密封拍卖也叫首价密封投标拍卖。根据这种拍卖方式的要求，所有买家须同时提交密封好的报价，因而没有人知道其他竞买者的报价。出价最高者支付其报出的价格。

This type of auction is distinct from the English auction, in that bidders can only submit one bid each. Furthermore, as bidders cannot see the bids of other participants they cannot adjust their own bids accordingly. Sealed first-price auctions are commonly used in tendering, particularly for government contracts and auctions for mining leases.
这种拍卖方式与英式拍卖的不同在于，每个买家只能出一次价。不仅如此，由于买家无法得知其他竞买人的报价，他们也无法相应地调整自己的报价。首价密封方式常用于投标，尤其是在政府项目和矿产租赁权拍卖中。
