关于爱因斯坦理论中引力张量必须给出的解析表达式
On the analytic expression that must be given to the gravitational tensor in Einstein's theory
摘要：
前言。虽然大多数广义相对论的教科书和研究文章都详细讨论了爱因斯坦和其他作者提出的代表引力场能量的伪张量的相对优点，但列维·奇维塔对真正引力能量张量的定义已经屈服于爱因斯坦的权威，几乎被遗忘。然而，它似乎值得仔细重新检查，因为它毫无疑问的逻辑合理性和它所需要的引力能传播的独特方式。
英文摘要：
Foreword. While most textbooks of general relativity and research articles discuss at length the relative merits of the pseudo tensors proposed by Einstein and by other authors for representing the energy of the gravitational field, Levi Civita's definition of a true gravitational energy tensor has succumbed to the authority of Einstein and is nearly forgotten. It seems however worthy of a careful re-examination, due to its unquestionable logical soundness and to the unique manner of propagation for gravitational energy that it entails.
