摘要：
本文对由二次拉格朗日量生成的一类四阶引力理论框架下的守恒原理展开了详细分析。我们尤其聚焦于相关的能量概念，并启动了与之相关的研究计划。我们还展示了若干解的示例，为该能量概念提供直观认识以助于对其进行阐释，并介绍了数个分析起来看似易于处理的研究案例。最后，我们在受限情形下给出了正能定理。
英文摘要：
In this paper we make a detailed analysis of conservation principles in the context of a family of fourth-order gravitational theories generated via a quadratic Lagrangian. In particular, we focus on the associated notion of energy and start a program related to its study. We also exhibit examples of solutions which provide intuitions about this notion of energy which allows us to interpret it, and introduce several study cases where its analysis seems tractable. Finally, positive energy theorems are presented in restricted situations.
