| 摘 要： | 现行的各种理论力学教材对惯量积的定义并不恰当，使得惯量张量的矩阵表示不符合数学中的表达习惯。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。章给出了惯量积的新定义。

| Abstract: | Because of the improper definition of the products of inertia in the books on theortical mechanics being used now, the matrix expression of the tensor of inertia does not conform with the convention in the mathematics.Therefore the unified expression for the components of a tensor of inertia in some textbooks is wrong. A new definition of the products of inertia is proposed in this paper. |
