In practice, there appears to be little room for such a view, for reasons that I will discuss under type C, and there are few examples of such views in practice.12 So I will take it for granted that a type-A view is one that holds that explaining the functions explains everything, and will class other views that hold that there is no unclosable epistemic gap under type C.

但在实践中，似乎这类余地很小（理由我会在C类的讨论中说），也几乎没有这类观点的例子。[12]所以我将承认A类观点就是吃人&解释更能就是解释一切&的观点，而归诸如&没有不可闭合的认识鸿沟&这些观点为类C。

The Bengtsson-Jacobson conjecture that "degenerate phase boundaries are always null" is studied by the mapping language in Chapter 4. By distinguishing a "phase boundary" from its image in the "covariant approach", the nulless of the image is proved. Time-like and null hypersurfaces in the degenerate space-times in the Ashtekar theory are denned, and then the phase boundary obtained by the "covariant approach" is shown to be always null.

我们在第四章用映射的语言分析了Bengtsson和Jacobson关于&相边界为类光&的猜想；通过区分&协变方法&中的&相边界&和它的像，我们证明了像的类光性；在定义了Ashtekar退化时空中的类时和类光超曲面之后，我们证明了&协变方法&得到的相边界必定是类光的。
