您要查找的是不是：
- 也许最早被普遍认为是黑洞的物体，是发射X射线的双星天鹅座X－l。Perhaps the first object to be generally recognized as a black hole is the X-ray binary star Cygnus X- 1.
- 例如正电子发射X射线摄影技术和单光子发射计算机化成像都可更清晰一些。PET and SPECT images could be sharper, for example.
- 发射X射线分析emission X-ray analysis
- 与正电子发射X射线摄影技术密切相关的是单光子发射计算机化成像（SPECT）。Closely related to PET is single- photon emission computed tomography, or SPECT.
- 小角度X射线分析Glancing incidence X-ray analysis
- 发射X线分析emission X-ray analysis
- 薄膜、多层膜和一维超点阵材料的X射线分析新进展NEW PROGRESS IN X-RAY ANALYSIS OF THE THIN FILM, MULTILAYERS AND ONE-DIMENSIONAL SUPERLATTICE MATERIALS
- 计算机X射线断层造影术和核磁共振成像主要在检查人体内部结构时有价值，而正电子发射X射线摄影技术在跟踪人体的新陈代谢时也很有用。Where CT and MRI are mainly valuable in viewing the body's internal structures,PET is also useful in tracking its metabolism.
