Then they brought the sample back to room temperature and exposed it to an X-ray beam from the facility while using a CCD detector to record the X-rays reflected from the surface of the sample.

然后他们将样品重置于室温状态，并使其接受X射线照射，同时使用CCD检测器来记录从样品表面反射回的X射线。

In X-ray crystallography, scientists turn large quantities of a protein or virus into crystal form, placing it in front of an X-ray beam.

运用X射线晶体学，科学家将大量的蛋白质或者病毒转换成了晶体形式，将其置于一束X射线光束之前。

The basis of applications is the output of X-ray laser with high brightness, high coherence, and good beam quality So it is a main aim and contents for studies to achieve X-ray laser.

应用研究的前提是获得能够满足应用要求的X射线激光输出，因此如何获得高亮度、高相干性、高光束质量的饱和X射线激光输出是X射线激光研究的首要内容。
