关于相对论质速关系推导方法的商榷

A DISCUSSION ON THE METHOD OF DERIVATION OF THE RELATIVISTIC MASS-VELOCITY RELATION

本文指出：不论用完全弹性碰撞还是完全非弹性碰撞推导相对论质速关系或相对论动量公式，两个守恒定律［ 即动量守恒和能量（ 或质量） 守恒］

To derive the relativistic mass-velocity relation, or relativistic momentum formula, both momentum conservation and energy (or mass) conservation must be used, no matter through perfectly elastic or perfectly inelastic collision.\;
