《物理学中的张量分析》主要内容:描述自然规律的物理定律和定理在坐标变换时,左右两边必须同样变换,才能保证这些定律和定理在任意坐标系中都成立。而如果左右两边都是张量,就能满足这一要求。因此,所有的物理定律和定理都具有张量等式的形式。
在经典物理学中,在不涉及各向异性连续介质时,还可以设法回避张量的概念,将一阶张量归结为矢量、二阶张量归结为并矢。到了相对论力学、电动力学和引力理论中,空间成为非欧氏的,甚至是弯曲的,运用张量分析就是不可避免的了。
但是,在现有的物理专业教学计划中,没有设立“张量”这门课,只在电动力学课中用到张量时略加说明。市面上也看不到适合物理专业用的张量教材,只是在一些电动力学教材中有关于张量的附录,而有一些关于张量的书则过于“数学化”,难度较大。这些对于从事物理学的教学和研究是非常不够和不便的,《物理学中的张量分析》的编写就是试图填补这一空缺。

很薄的小册子,对于张量及黎曼空间可以有初步的了解。就是书中符号陈旧了些。
