| 摘 要： | 随着计量学等学科的深入发展,量的含义及其分类,得到了进一步的明确.结合计量学、物理学和逻辑学的有关知识,通过分析指出,现行教材中,将向量定义为既有大小又有方向的量是值得商榷的.向量的确切定义应该是既有大小又有方向且遵循平行四边形法则求和的量.

| Abstract: | With the development of the discipline of measurement, the definition and classification of quantity are more accurate. Based on the knowledge of measurement, physics and logics, the author points out it deserves further discussion to define vector as quantity which boasts both size & direction in the current textbooks. Vector is quantity which not only boasts size & direction but also observes the law of the sum of parallelogram. |
