中文摘要:根据物理张量逆变和协变的性质,对张量角标位置的物理意义作了统一规定,给出了分量矩阵的具体形式,从而使得矩阵的运算性质能完全适用于张量运算,为定量讨论物理张量提供了可靠的数学依据。

PHYSICAL TENSOR AND ITS COMPONENT MATRICES
Abstract:According to the contravariance and covariance characteristics of physical tensors, the author has made a uniform regulation on the physical meaning of subscript and superscript in the expression of a tensor. Thus, a clear display of tensor matrix is given, the operational rule of matrix is made completely suitable for tensor calculus, and a reliable mathematic base is provided for quantitative analysis of the physical tensor.
