本章为核反应理论领域提供路线图，阐述核谱相关物理要素、实验结果与核结构的联系，明确直接与复合核反应同属核反应范畴，为后续详细讨论奠定基础。
AI 中文摘要
本章作为导论，将简要阐述两方面内容：一是决定核谱及相关能标的基本物理要素；二是观测到的实验结果（通常以截面形式呈现）与前述核结构之间的联系。本章的性质与范围是为核反应理论领域提供一份路线图，并为后续章节的更详细讨论奠定基础。其目的是提供一个概念框架，使读者能够理解不同反应理论方法如何相互契合，以及它们如何与核反应的基础物理相关联。读者将在本卷其他章节中找到关于两种看似截然不同现象的详细讨论：直接核反应与复合核反应。我们希望这份简短的章节能帮助读者认识到，无论我们谈论这两种现象中的哪一种，我们谈论的都是同一个事物：核反应。
英文摘要
This introductory Chapter will try to briefly address 1. the basic physical ingredients that determine the nuclear spectrum and the associated energy scales; 2. the connection between the observed experimental results, typically in the form of cross sections, and the underlying nuclear structure presented in the previous point. The nature and scope of the present Chapter is to provide a roadmap of the field of nuclear reactions theory, and to set the stage for the more detailed discussions in the companion Chapters. The aim is to provide a conceptual framework that will allow the reader to understand how the different reaction theory approaches fit together, and how they relate to the underlying physics of nuclear reactions. The reader will find in other chapters in this volume detailed discussions about the methods addressing two seemingly quite distinct phenomena: direct and compound nuclear reactions. We hope that this brief Chapter will help them realize that whenever we are talking about either of these, we are talking about the same thing: nuclear reactions.
