摘要
给出一个新的向量恒等式,首先采用函数论方法严格证明了该恒等式,其次从向量分析角度指出该恒等式与向量加法的三角形法则之间的密切联系,最后从质量守恒的观点给出该恒等式的一种物理解释。
In this note,a new vector equality is proposed.By function approach,we firstly prove this vector equality strictly.Then we point out the relation between the vector equality and the rule of vector addition.According to the law of conservation of quality,and we interprets it physically.
