sample beam的意思|示意

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。

This photomicrograph was obtained by scanning a beam of electrons across the sample while a detector kept track of electrons bouncing off its surface, betraying the specimen's outer shape.

这幅显微照片是通过扫描穿过样品的电子束而获得的，同时检测器对从样品表面反弹的电子进行追踪，这些电子显示了标本的外形。

TEMs work by firing a beam of electrons through the material and measuring how it absorbs and deflects the particles to build up an image of the sample.

TEMs 的工作原理是通过发射一束电子穿过某种物质，并测量它如何吸收和偏转粒子来建立样本的图像。
