2、定位球定位球就是用球杆击打主球的中点,印在击球时,采用中杆击球,靠腕部抖动的力量,使主球与目标相撞,两球相撞之后,主球将前进的力量传给目标球,使其前进,由于主球失去了旋转力量,故停在原地不动。打出定位球并不困难,只要在击球时运用腕部的抖动力量就行,否则便会成了推进球。另外,当主球与目标球距离太远时,很难打出定位球。这种击球方法,不但能为下一击球创造有利条件或给对方制造障碍球(见图①②③④),而且当目标球在袋口附近,主球、目标球和袋口三者在一条直线上,将目标球击落袋内,主球停留在相撞的位置上,可避免同落犯规。
2, Positioning Ball Positioning ball is the club hit the ball midpoint, printed on the shot, the use of shot in the pole, the power of the wrist shake, so that the main ball and the target collision, after the collision of two balls , The main ball will move forward to the goal of the ball, make it forward, because the main ball lost the rotation force, it stopped in place. Playing the positioning ball is not difficult, as long as the use of the wrestling power of the wrist on the line, otherwise it will become the promotion of the ball. In addition, when the main ball and the target ball too far away, it is difficult to play the positioning ball. This hitting method, not only for the next hit create favorable conditions for each other or create obstacles to the ball (see Figure ① ② ③ ④), and when the target ball near the pocket, the main ball, the goal of the bag and the three in a straight line On the target ball shot bag, the main ball to stay in the collision position, to avoid the same foul.
