| 摘 要： | 通过引入规范变换，消除了工程力学矢量数学表示上的物理缺陷，使规范化力学矢量与力学张量具有物理上的等价表示，从而奠定了不变性弹性力学的基础，为它在不同坐标下的具体应用提供了理论保障。

| Abstract: | By introducing the standard transformation, physical defects in the mathematical expression of engineering mechanical vectors are removed, and the standardized mechanical vectors that are equivalent to the mechanical tensors in physics are obtained, which lay the foundation of invariance of new type elastic mechanics, and provide a theoretical guarantee for using it in various coordinates. |
