The attack angle is from where you let go to where it hits the water.

接触角度是从你松手的地方到它碰到水的地方。

The sensor sits in the knob of the company's so-called Smart Bat and uses two accelerometers and a three-axis gyroscope to measure bat speed, hand speed, attack angle and other factors.

该传感器位于这家公司智能球棒的把手处，其中的2个加速器及一个3轴陀螺仪能够对球棒速度、手速、打击角度等其他因素进行测量。

We use laser projection methods to understand how to create wings and the attack angles and the number of wings and the geometries and the weight distributions to fully optimise the way that these structures are flying.

约翰：我们使用激光投影方法来了解如何创建机翼和攻角以及机翼的数量和几何形状以及重量分布，以充分优化这些结构的飞行方式。
