因此，有的教材给出的惯量张量各分量的统一表达式实际上是错误的。
Therefore the unified expression for the components of a tensor of inertia in some textbooks is wrong.
本文从物理学中转动惯量的传统定义出发，导出以并矢形式表示的惯量张量。
In the present paper, we derive the inertia tensor, expressed in a dyadic form, from the traditional definition of the moment of inertia in physics.
本交给出了惯量张量用其三个主要不变量表示的特征方程，为求特征值提供了一种代数方程解法；
This paper presents the eigen equation of inertial tensor expressed by the three principal invariants, which is an algebra-equation solution to calculate eigen value;
