查询词典 double star

Whenever a batter hits into a double play, the double play is constituted by a sequence of physical events. It does not follow, however, that we could redene "double play" in terms of precise sequences of physical motions. This is so despite the fact that, if a particular physical sequence constitutes a double play, any physically indiscernible sequence would constitute a double play as well. So being a double play "supervenes" on physical sequences.

无论何时，例如在散打中，一个击打得了两分，这个两分击打是被一连串物理事件所构成，它并不由此得到我们可以根据精确的连续的物理运动来重新定义&双分击打&，尽管事实是，如果一个特殊的物理连续构成了双分击打，但任何物理上难以区别的连续运动也会构成双分击打、（所以，是双分击打，附加在物理连续上。
