摘要 广义相对论中的场方程有时是通过在不变作用积分中使线性连接的分量和 2 价协变张量的分量服从独立变化来生成的。对这一过程的概念性反对意见以及其中固有的一些形式上的困难进行了详细讨论。与此同时，其他地方获得的某些结果得到加强并部分得到纠正。
ABSTRACT Field equations in general relativity theory have sometimes been generated by subjecting, in an invariant action integral, the components of linear connexion and the components of a covariant tensor of valence 2 to independent variation. The conceptual objections to this process, and some of the manifold formal difficulties inherent in it, are discussed in some detail. At the same time certain results obtained elsewhere are strengthened and in part corrected.
