日震推断可以在广泛的复杂范围内进行，从基于非常简单和高度理想化的模型问题（取决于数据的特定有限方面）的结果的论点到所有可用数据的各种正式数值反演。理想化的问题分析起来相对简单，并且提供了一种工具，可以对太阳结构的某些方面进行立即定性甚至定量的估计。如果选择得当，它们很可能大大增加我们对情况的理解;事实上，它们可以成为设计更正式的技术的极其有用的指南，这些技术虽然在数字上更精确，但往往也更不透明。因此，在整个光谱范围内使用方法通常是谨慎的。在这堂课中，我们将讨论一系列直接推理的技巧，并以一些热门话题为例加以说明。
Helioseismic inference can be made within a wide spectrum of sophistication, from arguments based on the results of very simple and highly idealized model problems which depend on specific limited aspects of the data to a variety of formal numerical inversions of all the data that are available. The idealized problems are relatively simple to analyze, and provide a tool for making immediate qualitative and sometimes even quantitative estimates of certain aspects of the structure of the sun. If well chosen, they are likely to add substantially to our understanding of the situation; indeed, they can be an extremely useful guide to designing the more formal techniques which, though numerically more precise, are frequently also more opaque. Therefore it is often prudent to utilize methods throughout the entire spectrum. In this lecture a selection of the techniques for making immediate inferences will be discussed, and illustrated with examples of topical interest.
