矢量力学中所涉及到的物理量有矢量也有标量，部分矢量根据质点组的运动状态有线量和角量．如果质点组有转动运动，则在该质点组的运动方程中肯定要涉及到角量，但是角量较线量相对复杂，理解困难．鉴于此，浅谈线量和角量二者关系，提出二者之间的统一表达式，以加深理解和灵活应用．

Vector mechanics involves vectors and scalars. According to the particle group movement state, some vectors in- clude linear vector and angular vector. If the particle group is in rotational motion, then angular vector will certainly be in- volved in the particle group equations of motion. However, angular vector is relatively more complex than linear vector and dif- ficult to understand. In view of this, this paper discusses the relationship between linear vector and angular vector, proposes a unified expression and thus deepens understanding and flexible application.
