Wutoumen refers to a type of elaborate gateway used in high ranking buildings through the Song dynasty, after which it declines in use. As we can tell from paintings and extant examples, the shape, size, and structure of wutoumen vary considerably. However, all wutoumen employ tall pillars flanking the gate. The name is likely derived from the black ceramic tube-shaped finials on the top of these tall gate posts (Cefu yuangui 冊府元龜, 1013). Detailed records of wutoumen exist in the Song dynasty Yingzao fashi (1103, Li 2009, 6.2a-4a).

X-ray absorption spectroscopy technique that analyzes the modelling of the dominant edge feature, and its pre-edge, that occur at the frequencies that correspond to transitions between atomic levels.

X-ray spectroscopy technique in which an intense, tunable X-ray beam of variable frequency from a synchrotron radiation source is directed at a sample and the absorption of the X-rays is measured as a function of frequency.

Radiography by secondary electron emission, an imaging technique. An example is for technical examination of painting, that records differences in intensity of electron emissions from adjacent pigments.

Computerized axial tomography in which the pixel sizes of the cross-sections of the 3-D object examined by radiography are in the micrometer range.

A form of spectroscopy in which photoelectrons excited by a beam of monochromatic x-rays are measured in order to find the characteristic binding energies of electrons at particular levels of the sample, thus identifying elements present there.

Technique applying x-ray diffraction to crystalline or powder samples in order to ascertain their structure.

Having the form or plan of two intersecting bars or lines of equal length, in which the intersection does not necessarily form right angles, and where the bars run diagonally across the vertical plane, that is, the base of the form rests on two arms that are not at right angles with the horizontal base plane. Resembling the letter "X." Use "cruciform" for forms or plans having two intersecting lines or bars at right angles, whether or not the bars are of equal length, and where the base of the form is perpendicular to the horizontal plane.
