Chapter 2 establishes a helicoid model of the 3D curved shock surface, which is a fundamental means for investigating the sweep of the 3D shock surface In chapter 3, the first step is to make definitions and detail concepts about various viewpoints of shock surface sweep. Secondly, those sweep angles of the 3D shock are calculated. After that, with the aid of the helicoid model, two general structure similarity variables are derived which are independent of any model, and their importance in shock structure investigations is discussed.

第三章首先给出激波曲面掠的各种基本概念，计算相应掠角；又借助螺面模型得到一般性的掠相似参数，并分析了它在激波结构研究中的意义，设想了激波气动掠参数的测量方法；第四章依据螺面模型探讨了前缘曲线掠与前缘激波曲面掠的关系，可能存在的均匀激波曲面、简单非均匀激波曲面和它们的运动学设计方法，其中得到一些很有用的概念。
