厚薄与瞄球点当母球碰到第一副球后,要准确无误地滚往第二副球,这是得分的依据,否则就没有得分的希望。因此撞球时,必须掌握好母球与副球碰撞时的厚薄比例,从图例1中我们可以看出,球撞到中央,以及撞到左右二分之一、三分之一与四分之一的不同厚薄。对于初学者而言,应以中心上的撞点为主要撞法,用不同力道试试不同厚度所产生的母球分离角。另外值得注意的是,接触点与瞄球点是不同的,这一点可参考图例1来仔细体会。入射角与反射角当母球碰到靠身时,母球往靠身前进的角度便称为入射角,而碰到靠身后被反弹继续前进的角度就叫做反射角。这些角度因撞点、力道及旋转的不同而有所不同,对此大家要多练习才能了解清楚。如果撞母球中心碰到靠身时,反射角等于入
Thickness and aiming point When the cue ball hits the first pair of balls, it is necessary to roll the ball exactly to the second pair of balls. This is the basis for scoring, otherwise there is no hope of scoring. Therefore, when a billiard ball, must master the thickness of the cue ball when the collision rate, from Figure 1 we can see that the ball hit the center, and hit the left and right half, one third and one quarter Different thickness. For beginners, the center should hit the collision point as the main method of collision, with different strength try different thickness of the parent ball separation angle. Also worth noting is that the contact point and the aiming point are different, which can be seen with reference to Figure 1 to carefully understand. Angle of incidence and reflection angle When the cue ball hit the body, the cue to the body forward angle is called the angle of incidence, and hit the body by the bounce to continue to move forward angle is called the reflection angle. These angles are different due to impact points, strength and rotation, and we need more practice to understand clearly. If you hit the club center by the body, the reflection angle equal to into
