摘要
本文利用向量函数和它的导函数所组成的零值混合积为工具统一刻画了向量函数具有某种特殊几何性质或向量函数所表示的曲线成为某种特殊曲线的条件,并给出了这些零值混合积的几何意义.
In this paper,the condition for a vector function to have the certain special geometric property or a curve represented by vector equation to be a certain special curve is given by using the tool of zero value mixed product which is formed by the vector function and their derivative functions. In addition,the geometric meanings of zero value mixed product which is mentioned above are given.
