- Based on the conception of velocity of rotation around a fixed point of rigid body, this paper rigidly proves that angular velocity is second-order anti-symmetrical tensor, and velocity vector is vector product of angular velocity and position vector.
从刚体定点转动的速度概念出发，利用张量变换的性质严格地证明了瞬时角速度矢量是二阶反对称张量，而速度恰是角速度矢量与位矢的矢积。 - The paper deduces the general formulae of the sweet point about the rotation around a fixed point of rigid body, from the kinetic equation of it, and puts formulae to use for special rigid bodies.
从刚体定点转动的动力学方程出发，推导定点转动刚体打击中心位置的普遍表达式，并通过特例加以应用。
