只需要爱因斯坦的相对论的例子就可以证明，在一个“舒适的正常”世界之外，经典物理学几乎肯定会失败。它必须被更广泛和更普遍的概念所取代，这些概念是通过观察、理论化和测试的渐进过程获得的。高速基本粒子物理学是一门发展中的科学，困难、尝试性的，而且仍然不令人满意。它在很大程度上依赖于费曼图分析，本卷（从第一章开始）。11，是第二部分的工作，其中第一部分处理相对论量子力学）的目的是提出定性计算，分析和理解的费曼图，以更广泛的社会物理学家。规范量子化使过渡从经典的量子理论，产生粒子解释的电磁场。由正则量子化构造的散射振幅的微扰展开被证明与前面的工作量中给出的费曼规则相同。通过进一步的图形分析，阐述了色散关系法。最后，证明了重整化量子电动力学对每一级相互作用的有限性。虽然它不治疗温格的变分方法，也没有广泛处理的发展，公理场论和S矩阵，这本书（第一部分）将强烈兴趣物理学家的辛劳理论的高速粒子。
It needs no more than the example of Einstein's theory of relativity to demonstrate that, outside a'comfortable normal'world, classical physics is almost certain to fail. It has to be replaced by wider and more pervading concepts, acquired by a gradual process of observation, theorising and testing. The physics of high-speed elementary particles is such a developing science, difficult, tentative and still unsatisfactory. It relies heavily on a Feynman-graph analysis, This volume (which starts at chap. 11 and is the second part of a work of which the first part dealt with relativistic quantum mechanics) aims to present the qualitative calculation, analysis and understanding of Feynman graphs to a wider community of physicists.The canonical quantisation makes the transition from the classical to the quantum theory, yielding a particle interpretation of the electromagnetic field. The perturbation expansion of the scattering amplitude constructed by canonical quantisation is shown to be identical with the Feynman rules given in the preceding volume of the work. With further graph analysis, dispersion-relation methods are illustrated. Finally, the finiteness of renormalised quantum electrodynamics to each order of the interaction is proved. Although it does not treat Schwinger's variational approach, nor deal extensively with the developments in axiomatic field theory and the S matrix, the book (with its first part) will'strongly interest physicists in the toils of the theory of high-speed particles.
