摘要：
在Einstein-Hilbert引力中，讨论了以高阶导数和代表物质的标量场为基础的不同版本的类张量量。改进与超势的概念有助于理解其构造与意义的细节。在此基础上，本文声称，为定义微扰理论中高阶项所必需的高阶导数，不会破坏模型的物理内容。
英文摘要：
Within Einstein-Hilbert gravity, higher derivatives and a scalar field as representative of matter different versions of tensorlike quantities are discussed.The concepts of improvement and superpotential help to understand the details of their construction and meaning. On this basis it is claimed that the higher derivatives which are necessary for defining higher orders in perturbation theory donot ruin the physical content of the model.
