这样就可以实现倒置结构的X射线成像方法、等角扇束的扫描方法，以及本文所提出的凹面源加点探测器的锥形束扫描方法，而且还避免了使用成组点探测器带来的性能不一致性。

Equivalently, you could say that Y is a descendant of X, or that there is a chain of parents leading from commit Y to commit X.

同样地，你可以说 Y 是 X 的一个后裔，或者说存在一个从 Y 追索到 X 的世系族谱。

X-ray ESCA and X-ray diffraction instrument are used to analyze elements and structure on EDMed surface.

采用X-射线能谱仪和X射线衍射仪对混粉电火花加工表面进行了成分和结构分析。

The existing points and lines would form a closed geometric shape. If we put the new point Z outside the closed geometric shape at first and later then found that the point Z has neighboring relationship with the existing point A which is inside the closed geometric shape, we could not link point Z and A directly because that would bring line crossing. If we rearrange the point Z into the closed geometric shape, that also would cause a lot of work to do. With the help of Exclave, all problems could be solved easily. We use point X outside the closed geometric shape as the Exclave of the point A. Then the line between point Z and X could demonstrate the neighboring relationship of the point Z and A.

原有的各点和相邻线段往往会形成一个封闭的几何图形，如果我们把新增点 Z 设在原有的封闭几何图形外部，后来又发现该点 Z 和位于封闭几何图形内部的点 A 存在相邻关系，这时不能直接将两点连接因为那将产生交叉，而如果将点 Z 重新设在封闭图形内部也将导致大量的调整工作；此时借助外飞地的概念，可以轻松地解决上述问题，即在封闭几何图形外部设置点 X 作为点 A 的外飞地，两点使用同样的颜色，用点 Z 和点 X 的相邻线段表示点 Z 和点 A 之间的相邻关系。

Where subscripts e and x signify exit and any point x along the nozzle axis, respectively.

凡标e和X意味着出口和任何X点沿喷嘴轴，分别。
