〜在过去的几年中积累了有关布雷姆 - 斯特拉隆过程的大量信息。此信息包括各种 1 横截面计算和测量，这有助于提供更准确的过程描述。不幸的是，尽管有一些关于该主题的一般评论 3 可用，但该材料从未以易于参考的形式组装和集成。本文对 4 个轫致辐射截面公式和相关 1 个数据进行了连贯的总结。理论公式及其具体限制以方便实际计算的形式呈现。对于可以与实验 2 心理结果进行比较的情况，给出了对其准确性的估计。修正系数以数字或分析形式表示 3 。还包括有关电子-电子和厚靶轫致辐射的 6 个其他数据的简要摘要。没有给出电子和光子极化效应的结果7。第 IIB 节简要讨论了进行精确横截面计算的问题，并指出了已完成的计算的一般类型。各种横截面公式的总结在第 2 节中给出。 IIC。 IID 部分给出了从 IIC 中的各种公式导出的有用的图形信息8。部分
~ CONSIDERABLE information about the brems-~ strahlung process has accumulated during the 1 past several years. This information includes various 1 cross-section calculations and measurements, which 1 have helped to provide a more accurate description of the process. Unfortunately this material has never been 2 assembled and integrated in an easily referenced form, although some general reviews' on thesubject are 3 available. This paper provides a coherent summary of 4 the bremsstrahlung cross-section formulas and related 1 data. The theoretical formulas and their speci6c limitations are presented in a form convenient for practical 2 calculations. Estimates of their accuracy are given for cases where comparisons can be made with experi-2 mentalresults. Correction factors are indicated in 3 either numerical or analytical form. A brief summary of 6 other data pertaining to electron-electron and to thick target bremsstrahlung is also included. No results are7 presented for electron and photon polarization eGects. Section IIB briefly discusses the problem of making7 exact cross-section calculations and indicates the gen-eral types of calculations that have been completed. A summary of the various cross-section formulas is given in Sec. IIC. Section IID gives useful graphical informa-8 tion derived from the various formulasin IIC. Section
