Element-specific X-ray fluorescence microscope and method of operation

An element-specific imaging technique utilizes the element-specific fluorescence X-rays that are induced by primary ionizing radiation. The fluorescence X-rays from an element of interest are then preferentially imaged onto a detector using an optical train. The preferential imaging of the optical train is achieved using a chromatic lens in a suitably configured imaging system. A zone plate is an example of such a chromatic lens; its focal length is inversely proportional to the X-ray wavelength. Enhancement of preferential imaging of a given element in the test sample can be obtained if the zone plate lens itself is made of a compound containing substantially the same element. For example, when imaging copper using the Cu La spectral line, a copper zone plate lens is used. This enhances the preferential imaging of the zone plate lens because its diffraction efficiency (percent of incident energy diffracted into the focus) changes rapidly near an absorption line and can be made to peak at the X-ray fluorescence line of the element from which it is fabricated. In another embodiment, a spectral filter, such as a multilayer optic or crystal, is used in the optical train to achieve preferential imaging in a fluorescence microscope employing either a chromatic or an achromatic lens.

Document type definition generating method and apparatus, and storage medium for storing program

There is disclosed a document type definition generating method comprising, in a structured document provided with a tag having an element name in each document element, judging a physical structure of each document element from indention, blank lines, and positional relation between tags, analyzing words and phrases in each document element, and judging a semantic structure of the document element based on words and phrases connection and word types. When the physical and semantic structures of document elements having tags different in element name are similar, the elements are regarded as being of the same type and one element name is excluded from a list for generating the document type definition. When the physical and semantic structures of document elements having tags with the same element name are different, the elements are regarded as being of the different types and one element name is changed. Furthermore, the words and phrases between a start tag and an end tag with the same title are analyzed, and the information to be included between the tags is obtained to generate the document type definition. Thereby, tag meaning is correctly treated, and the document type definition with tag redundancy removed therefrom is generated.
