我们讨论了激发高阶引力理论及其宇宙学分析的问题，并介绍了一条规则，该规则指出，这些理论可以被视为测试某些性质是否与量子理论相关的工具。我们讨论的物理性问题所产生的后果的共形变换定理，制定一个一致的一阶形式主义等理论的问题，也是各向同性问题的一类广义宇宙学。我们指出，这一领域可能有一个重要的作用，在澄清问题也出现在广义相对论。
We discuss the issue of motivating the analysis of higher order gravity theories and their cosmologies and introduce a rule which states that these theories may be considered as a vehicle for testing whether certain properties may be of relevance to quantum theory. We discuss the physicality issue arising as a consequence of the conformal transformation theorem, the question of formulating a consistent first order formalism of such theories and also the isotropization problem for a class of generalized cosmologies. We point out that this field may have an important role to play in clarifying issues arising also in general relativity.
