规则 RULES： 27-2a

　　暂定球处置程序

　　如果球可能在水障碍区以外成为遗失球或可能界外时，为了节省时间，球员可以按照规则27-1打暂定的另一个球。球员必须向比洞赛中的对手、比杆赛中的记分员或同伴比赛者通报他要打暂定球的意向，并且必须在他或他的伙伴开始寻找初始球之前打球。如果他没有及时履行这一程序并且打了另一球，该球不是暂定球，在球员接受了加罚一杆和距离的处罚（规则27-1）之后，该球成为使用中球；初始球成为遗失球。（发球区上的打球顺序—见规则10-3）

　　注：如果按照规则27-2a打的暂定球可能在水障碍区外遗失或界外，该球员可以打另一个暂定球。如果打了另一个暂定球，则它与前一个暂定球的关系等同于第一个暂定球与初始球的关系。

Procedure For Provisional Ball

If a ball may be lost outside a water hazard or may be out of bounds, to save time the player may play another ball provisionally in accordance with Rule 27-1. The player must inform his opponent in match play or his marker or a fellow-competitor in stroke play that he intends to play a provisional ball, he must play it before he or his partner goes forward to search for the original ball. If he fails to do so plays another ball, that ball is not a provisional ball becomes the ball in play under penalty of stroke distance (Rule 27-1) the original ball is lost. (Order of play from teeing ground— see Rule 10-3.)

Note: If a provisional ball played under Rule 27-2a might be lost outside a water hazard or out of bounds, the player may play another provisional ball. If another provisional ball is played, it bears the same relationship to the previous provisional ball as the first provisional ball bears to the original.
