归零实例

mileswei2018

0 三角形的中心，准备知识。

5发后的弹孔

弹孔的中心连线

三角形各边的长度中间点

三角形的顶点连接对边中间点，画出三条连线。交点就是该区域中心点。

区域中心到靶子中心（瞄准位置）的距离， 垂直方向：6.5 cm. 水平方向：2.4cm。

研究光瞄的说明书：

mileswei2018

垂直偏差：2.559 inches 。水平偏差：0.944 inches

射击点距离靶子的距离：6 yards。
1 inch的偏差，在6 yards 上需要X 的Knob修正值：

16/25=x/6 , x=16*6/25==4 Knobs。

所以，此例中垂直方向的修正量是 2.559*4==10 Knobs。水平方向的修正量是 1 Knobs.

请各位师兄指点。谢谢。

另外，计算错误，6 yd上 0.944"的偏差，需要调 4 x 0.944 x 100/6 = 63。

谢谢师兄。没看懂你的算式。能否解释一下，谢谢。

6 yard太近了，平感觉都可以归零。 air rifle 至少要10 yard。我刚开始也是在卧室里6yard归零，之后拿到后 ...

花猪，太猛了吧。

谢谢各位师兄。我好好研究一下。

又打了一组，水平偏差4.5cm, 垂直偏差1.9cm. 到靶纸距离6yard.

下周找gun smith去。

镜子每格调节是固定角度的，在100yds上是0.25，你现在靶子在6yds上，那么画个三角形算一下，在6yds上就是 ...

谢谢师兄，画了相似三角形，确实是你的算法正确。

感谢师兄耐心指点。回头我找gun smith先校准一下。后面考虑换家伙。

谢谢师兄。毕竟外弹道在垂直方向是抛物线。
