在弹性力学的本科教学中，采用了矩阵形式来表达各物理量间的相互关系。文中主要讨论了以应力、应变、位移为基本量的各物理量间的矩阵表达形式，包括基本方程、边界条件以及不同坐标间的基本物理量的转换关系。采用矩阵表达形式不仅书写简洁、记忆容易，而且表现直观、便于理解。

In undergraduate teaching of elasticity, matrix representations of basic quantities and equations were used. We gave matrix representations of relationships between basic physical quantities, such as stress, strain and displacement, including basic equations, boundary conditions, and coordinate transformations of basic physical quantities. Matrix representations are simply written, easy to be memorized, and easy to be understood.
