提出了一种快速 X 射线衍射方法，用于原位观察液固界面上的表面中间结构。 It used a combination of higher-energy monochromatic synchrotron X-rays in grazing incidence and an X-ray two-dimensional detector.整体图案是通过一次曝光原位拍摄固定在一定角度位置的 Au (111) 电极表面的倒易晶格空间。我们通过观察从重建表面到本体终止表面的表面结构相变期间重建表面棒的图像，推断出表面中间体的晶域形状的变化及其较小的晶格畸变。还观察到表面晶域的各向异性形状。
A rapid X-ray diffraction method was proposed for in situ observation of a surface-intermediate structure on a liquid–solid interface. It used a combination of higher-energy monochromatic synchrotron X-rays in grazing incidence and an X-ray two-dimensional detector. Overall patterns were in situ taken, with one-time exposure, of the reciprocal-lattice space of a Au (111) electrode surface which was fixed at an angular position. We deduced change in crystal domain shapes of surface intermediates as well as its smaller lattice distortion by observing images of reconstructed surface rods during a surface-structural phase transition from the reconstructed surface to the bulk terminated surface. An anisotropic shape of surface-crystal domains was also observed.
